In Eclipse I have two maven projects A and B, where A is a parent for B. The directory structure is the following:
A/pom.xml
A/B/pom.xml
A/B/...
Then I use File search (Ctrl+H) to find any file in the project B. The search result window shows the file two times with different relative paths:
A/B/<my_file>
B/<my_file>
So, the same file is shown twice. Obviously, the first search result is reduntant. Is there a way to exclude these duplicate search results?
What I personally do to avoid this is marking each module in the parent project as derived (right-click on the folder > properties > Attributes: Derived).
Then when you perform a file search, uncheck "Consider derived resources" (I don't think it is checked by default) and you won't get the A/B/<my_file>.
The only inconvenience is that you must do this for each module, and each time a new module is added.
In an open resource window (cntrl+shift+R), click on the arrow on top-right and check "Filter Duplicated Resources". This worked for me.
Checking Window -> Preferences -> Maven -> Hide folders of physically nested modules (experimental) worked for me in Mars.1 Release (4.5.1).
After checking it I closed all projects within eclipse, deleted eclipse project files (.project, .classpath and .settings) and reimported my maven projects.
I had similar problem.
My solution for this problem was
Create eclipse "working set" of projects to search
Set this working set as option into search dialog
Search in it
Windows - Preferences - Maven - Hide folders of physically nested modules
I agree with Damon Horrell.
Go to Windows - Preferences - Maven - Hide folders of physically nested modules (make sure the checkbox is checked).
Note: Make sure to re-import the maven project into eclipse to see the changes.
Within the parent project, child ones were already visually hidden in my case, but still found through search and Ctrl-click links.
I solved this by using Resource filters:
Right-click (parent) project > Properties > Resource > Resource Filters
Click Add Filter..., select Applies to -> Folders and enter one child project's folder name, click OK
Repeat 2. for all child project folders
By the end, you should have something like this:
There is an ancient bug which requests Eclipse to support nested projects. Opened 2008, won't happen soon, I guess.
Since Eclipse doesn't support Maven's default nested module layout, you have to import each module individually which doesn't confuse Eclipse but it can confuse you as you can see in the search results. Similar things happen when you start to save launch configs in a module.
There are several possible solutions:
Get used to ignoring half the search results. Takes some discipline but no magic.
Make sure your root project doesn't contain anything important that you might want to open from Eclipse (i.e. move the parent POM to a new module which must be a child of the root project). Now you can close the root project.
Takes some discipline where to put things in your project and it's clumsy when you have to add new modules.
Use the flat multi-module approach. This is an extension to #2, it looks odd and there might be plugins that are offended by that. So if you use a lot of nonstandard plugins, you should check whether they like the new layout.
As a new joiner, still couldn't comment but I'd really like to add something to the best answer. It works! It not only removed the duplicate files for me (one from child module and one from parent module), it also removed the class files from parent module).
But it added the folder to my .gitignore which will cause problem for new files/directories added later. I just reverted the change to .gitignore and it still works in eclipse.
Find this answer to disable auto change of .gitignore
EGit and Eclipse modifies .gitignore file but it should not
You can solve this problem using a flat multi-module approach.
Caveats may apply if you're using the maven-release-plugin with a version control system other than Subversion.
In addition to "Hide folders of physically nested modules" mentioned, you could uncheck parent modules when importing Maven project:
It seems like all my projects (except one) disappeared from the view Project Explorer.
I'm using Eclipse Java EE IDE for Web Developers.
Version: Helios Service Release 2
Build id: 20110218-0911
Note: all the projects are present on the file system.
How to bring them back? Any ideas?
This happened to me. I'm still not sure how, but the reason was that my workspace meta data had become corrupted, probably due to Eclipse being improperly shutdown. The solution, as explained here, is to:
Note, steps 2 & 3 are optional if Eclipse isn't crashing, but just not showing any projects.
Close Eclipse.
cd /home/user/workspace/.metadata/.plugins
mv org.eclipse.core.resources org.eclipse.core.resources_bak
Start Eclipse
Do File->Import
General->Existing Projects into Workspace
Click the "Select root directory" field and browse to each subfolder in your workspace folder, and import.
For me, this was very tedious, since I had several dozen projects in my workspace, but it's the only solution I found short of restoring my entire workspace from a backup.
Edit: This answer is now quite old, and better solutions may now exist. Although I haven't had need to try it, I recommend attempting #antonagestam's solution first, as others have suggested it may be faster and more effective.
Edit: Since it's fairly simple, I'd recommend trying antonagestam's solution first. However, this problem recently re-occurred for me, and that solution did not work in my case. But neither did it interfere with this solution.
I had the same problem in Aptana, all of a sudden my projects were gone. Solved it by going to the drop-down menu in Project Explorer and going Top Level Elements -> Projects.
Go to
File --> Import --> General --> Existing Project into Workspace
Then,
In Root Directory Enter the workspace path where all your projects saved & click refresh as below
And Click Finish
I was having the same problem for Android projects in Eclipse. This link was very helpful in restoring the missing projects.
Go to 'File->Import->General->From Existing Project'.
Select the root folder to the Workspace.
Click on the 'Refresh' button.
Select the required projects and click 'Finish' button.
I had the same problem in Luna, Suddenly my projects were gone in start-up.
I solved this by select Deselect working set option in the drop-down menu in Project Explorer.
Note: I post this answer even this is not a right answer for this question.
Since I search for Luna and came here,while trying with discussed things I was find this solution. This may help others.
Click on Windows > Open Perspectives > java
, Press Ok. Project Explore will come back on screen..
My solution is
open view menu and select "Top Level Elements" and set "Projects"
If any of the previous methods don't work for you then delete your old workspace, create a new workspace and put it by default. You can do this by launching Eclipse twice - the second time it asks you for the workspace ;). Then re-import all your projects there and say "problem, goodbye".
Mona is correct - Make sure that you have the task list set to show ALL as the image shows. Click the arrow to the left of the project if you want to re-factor your filter. Reset your perspective if you do not see the task list.
Today 22-03-2016, I check again this question and using ECLIPSE MARS I solved with:
Having Eclipse opened, go on FILE -> RESTART
Go on same workspace and I have all project on "PROJECT EXPLORER"
Sometime also this operation, will solve (Clicking on Projects dor see all project!!)
So Other solution is:
if you use the "Task List" view of Eclipse, it will sometimes try to hide files or projects that it thinks are not associated with a given task (i.e. any file that was not opened while you had a certain task selected as the current task). If you want Eclipse to stop hiding files
in that case, you can just delete all tasks.
Or you may also restart your eclipse and by just closing the project and then opening it again (from the right mouse click context menu) the files will be restored.
If that doesnt get your projects back then check the "filters option" (Click on right corner of Project Explorer tab and open context menu. Select Filters option from menu) and make sure that your projects type isnt checked.
you should check the active Working Set - make sure it is off.
When this happened to me I had somehow set the Project Explorer to only display Working Sets. I had none, so nothing was displayed.
To fix it, I went to the Project Explorer View Menu (next to the Minimize and Maximize icons in the Project Explorer), Top Level Elements -> Projects.
Thanks to #antonagestam for pointing me in the right direction.
It seems it happens to us all. I was happily hacking away at javascript, nowhere near all the nasty hibernate java stuff, and boom, "cant find org.jboss.logging.BasicLoging".
I havent touched anything!.
After an hour or so of trying to make that appear, restarting servers, mysql, eclipse, adding jars that weren't needed before,I deployed the fix all solution, the off button.
Then zap, no project.
(I am still none the wiser as to why calling Configuration() should now require jboss-logging...jar, maybe I needed it all along for when bad things happen)
My input is
use git, keep as little of your stuff in the eclipse workspace area as possible. Then just import project from existing git repo when eclipse loses it's marbles.
I also lost my server config. it's there but eclipse insists there no server config stuff and bombs. So make another one, I've expressed my feelings about eclipse in my new server name, and copy your apache xml configs (workspace/Servers/I_Love_Eclipse) over from the original perfectly good directory.
Not sure how/why, but this happened to me once when I added a task to Mylyn. Seemed that mylyn was filtering my projects. When I deleted the task they all came back.
None of the answers provided here worked for me. My Enterprise Explorer was completely grey and I couldn't even import or reimport projects.
In my .metadata.log I saw this error:
assertion failed: working set with same name already registered
So I deleted these file:
.metadata.plugins\org.eclipse.ui.workbench\workingsets.xml
Now I can see all my projects. I didn't have to add them back again.
I found a solution that worked better for me. Under my home folder I found a workspace/.metadata folder. I copied this folder into my eclipse workspace, replacing the .metadata folder that had been there. When I started Eclipse everything was back to the way I had left it - all projects present, all open files were still open, etc. Just like nothing had happened! I'm using Neon.
As a preliminary (before reimporting everything), here is a solution to recover working sets in which project were (if any).
I had more than 100 projects and each was in one of 14 working sets.
If your top level elements changes (accidentaly or not if it is a bug) from "Working set" to "Projects", you only see projects that are NOT in a working set, and if, as I do, you don't have any projects outside a working set, you think all is lost because you cannot see anything (blank package explorer).
So the solution is now obvious: click on the top left small white triangle MENU, than select "Top level elements", than select "Working sets".
You also have the possibility to rearrange the working sets list items.
Hope it helps
Unfortunatly the working sets were empty after the recovery, but at least I
recovered their names.
Config: Eclipse Oxygen.2 Release (4.7.2) with Java 1.8 on Windows 10.
Got this issue on returning to an Eclipse project on a VM after leaving it untouched for maybe a couple of weeks.
I started to apply the accepted answer, but when I got to the step of renaming the folder and had exited Eclipse, I saw there was an instance of Eclipse still running. I realized Windows had for some reason started a second instance of Eclipse when I hit the taskbar button. The second instance had been unable to access the workspace while the first instance was using it.
Once I undid my folder rename, and closed and restarted the original instance of Eclipse, I was able to use File->Switch Workspace to get my normal workspace back.
Solution that Cerin provide, importing each time that this problem happens, could be boring.
So I've implemented a script that control if workspace setting exits: if not, restore it to default.
I have an eclipse shortcut icon on the top panel that execute:
/opt/eclipse/checkWorkspace && /opt/eclipse/eclipse
Script checkWorkspace is the seguent:
#!/bin/bash
ECLIPSE_CONFIG_PATH="/opt/eclipse/configuration"
ECLIPSE_CONFIG_FILE="config.ini"
ECLIPSE_CONFIG_SETTING="osgi.instance.area.default"
DEFAULT_WORKSPACE_PATH="#user.home/workspace"
ECLIPSE_LOG="/var/log/eclipse.log"
cd ${ECLIPSE_CONFIG_PATH}
function sedeasy {
sed -i "s/$(echo $1 | sed -e 's/\([[\/.*]\|\]\)/\\&/g')/$(echo $2 | sed -e 's/[\/&]/\\&/g')/g" $3
}
WORKSPACE_EXISTS=$(cat ${ECLIPSE_CONFIG_FILE} | grep ${ECLIPSE_CONFIG_SETTING})
# If workspace setting doesn't exists
if [ -z "$WORKSPACE_EXISTS" ]; then
echo "worskspace setting not exists, resetting to default." >> ${ECLIPSE_LOG}
newConf=${ECLIPSE_CONFIG_SETTING}"="${DEFAULT_WORKSPACE_PATH}
echo ${newConf} >> ${ECLIPSE_CONFIG_FILE}
else
# if setting exist but it is empty
vals=(${WORKSPACE_EXISTS//=/ })
length=$(echo ${#vals[#]})
if [ "${length}" -lt 2 ]; then
newConf=${ECLIPSE_CONFIG_SETTING}"="${DEFAULT_WORKSPACE_PATH}
confToReplace=$(echo ${vals[0]})
sedeasy ${confToReplace} ${newConf} ${ECLIPSE_CONFIG_FILE}
echo "worskspace exists but is empty, resetting to default." >> ${ECLIPSE_LOG}
else
echo "Worskspace already set:" "${vals[1]}"
fi
fi
Maybe could be semplified, but works.
I tried many solutions. I found mine in the drop down menu of the Entreprise Explorer:
- Deleting org.eclipse.core.resources has no effect.
- "Top Level Elements -> Projects" was already checked for me; swtiching with Documents has no effect.
- Selecting all extensions in the filter option of the drop down menu has no effect at first sight, maybe it solve part of the problem.
The solution come from "Unselecting documents" (third choice in the Entreprise Explorer drop down menu). I think that choice reset the filtering of documents displayed in the Explorer.
Hope it'll helps

Tedious but it worked for me (Kepler):
Using the OS zip utility, zip everything below the project workspace folder to a zip file, to be placed in a separate directory (will use c:\tmp\workspace.zip as an example).
Unzip workspace.zip to the c:\tmp directory. Assume there's a project folder called Project1
a. Ensure all the files in Project1 have Full Control permissions for Everyone or at least 777 permissions.
Remove all the project folders in the Eclipse workspace.
Recreate each project one by one according to its original type (Java, Dynamic Web, etc.). (Will use Project1 as an example.) Do not add anything.
In Eclipse, do File -> Import -> File System. Then select c:\tmp\Project1 as a source
Select the workspace Project1 as a destination. Do not overwrite any file.
In Eclipse, refresh the project and test it. It should work.
Also had this Problem.
My Solution was to uncheck the Box PyDev: Closed Projects, even if those hidden Projects are PHP and NOT Python Projects. (Strange BUG in Eclipse/Aptana???)
Be aware that even "Closed Projects" (a Topic above Pydev closed projects) is also unchecked. So you have to uncheck both Settings.
this: eclipse shows only "open projects" in project explorer
All of my projects were closed and I had hid the closed projects in the settings.
So to open projects go to top right view menu, and uncheck Closed Projects option. Assuming it is checked already.
Do the following steps
File --> Import --> Existing Projects into Workspace
Select the root directory as ur old root folder
Finish.
Yahoo.. There is ur old projects again in ur project explorer
1) File > import > Existing projects into workspace
2) Choose your workspace folder
3) select all of your projects
4) finish
All are OK with above way !!!
File - Import - Existing projects into workspace - browse - choose your workspase - done!
If Eclipse was killed during a shutdown, the projects database may become corrupted (the project database is normally located in: workspace/.metadata/org.eclipse.core.resources/.root/1.tree).
A message like this will be logged in Workspace/.metadata/.log:
!MESSAGE Could not read metadata for '.../.metadata/.plugins/org.eclipse.core.resources/.root/.markers'.
The data is lost. You need to import your projects again (File->Import ->
General->Existing Projects into Workspace).
The list of projects that were in the workspace can still be seen in .metadata/org.eclipse.core.resources/.projects/.
Projects located outside the workspace will have a .location file with the path to the project.
I also had the same problem.
file>restart.
Projects and modules appeared after restarting the eclipse, but faced new error;
An internal error occurred during: "AppXray Indexing...". java.lang.NullPointerException.
So it's good to be on safe side, import the project again in a new workspace.
if you go to Quick Access and type in Projects you will get it your projects back.
I've discovered a curious thing on my Mac. At some point I apparently created two different Eclipse workspaces, one in /Users/username/workspace and the other in /Users/username/Documents/workspace (this may have happened as a result of some troubleshooting a while ago). I never knew until now that anything was amiss because the contents of both workspace folders are visible in the Eclipse Package Explorer.
I only just noticed because I'm trying to use Mercurial from the command line and couldn't find the project folder to create a repository. After some cursing I found the other workspace. The other strange thing is that from Eclipse's perspective, projects from both workspaces appear to be housed in /Users/username/Documents/workspace, even though some projects are only in /Users/username/workspace.
I believe the problem itself is easily solved (import things from one workspace into the other) but I want to understand why it is happening, and haven't been able to find anything about it elsewhere. My suspicion is that this is being caused by metadata that is telling Eclipse about the workspaces in both locations, and / or some Mac file system magic. However, I'm not sure where to start looking. Where I should begin? What might be causing this?
First, I personally prefer Eclipse to present me with a combo-box allowing me to select the workspace to be opened. You can set it in the preferences, under General -> Startup and Shutdown -> Workspace.
If you prefer not to be asked, you can specify the workspace explicitly in the eclipse.ini file (inside the Eclipse.app package) by using the -data switch (more about Eclipse.ini: http://wiki.eclipse.org/Eclipse.ini#Mac_OS_X_Example, all the switch options are in the Eclipse help).
Projects are not required to be inside the workspace. I like storing my work outside the workspace, since I usually share projects between workspaces. When creating a project, you can specify a location which is different than the default location. You can see the location of the project by right clicking it in the Project Explorer and selecting Properties.
I know it's possible in eclipse to open file browsers from your project's resource browser, but is it possible for files that aren't part of your project ? Typically external includes are not found in your resource browser...
If there is the equivalent of $(resource_loc) for the editor, it would work.. But I wasn't able to find it. Can anyone help me on this ?
Thanks!
EDIT : I Found StartExplorer, but it doesn't work for me. It is hardcoded to use WINDOWS explorer or cmd.exe. Also, it still requires you to use the resource browser. Other than that it can open paths selected in the editor, but they must be full paths.
EDIT 2 : StartExplorer seems to have been upgraded. I no longer use eclipse, but if someone else is still looking for this, I'd look again at their stuff!
For eclipse Luna (4.4) and later, You can use: Right Click->Show In->System Explorer
"Window" -> "Open Perspectives" -> "Remote Systems", then a view with root 'Local' node will be displayed.
While in Project Explorer pane, to browse files of any node, right click and select Show in Remote Systems view to get there.
From StartExplorer website:
This plug-in is inherently not platform-independent. Currently, the following operating systems/desktop environments are supported out of the box: Windows, Mac OS, Linux with Gnome, Linux with KDE, Linux with Xfce, Linux with LXDE.
As far as I know you have to create a linked folder for your external includes to achieve your goal. After that you can use StartExplorer for you externals as well. If you do not like that plugin you could try another similar one called EasyShell which is a similar one but you can configure all of its commands.
EasyShell seems quite descent to me (used in Ubuntu). It gives you the choices to open the Nautilus, to open the shell, to run a file and to copy the selected path. All of them appear with a right click on the package explorer of Eclipse. The installation was with no problems. Therefore, I would suggest it.
Hope I helped!
You might want to try eExplorer, see my answer on https://stackoverflow.com/a/24149472/612123
If you are using git, you can open Window > Show View > Other > Git Repositories. That will give you a Git Repositories explorer, which shows the Working Tree. The Working Tree will show all files in the filesystem, even temporary ones you created that are not added to git yet.
Another way is to open Window > Perspective > Other > Git.
Shortcut key can also be created in Eclipse>Help>Preferences>General>Keys
I enjoy using NetBeans, especially for development with Maven, however, I've found recently that I've been working with three different branches of the same code base in different parts of the development cycle.
One of the things that Eclipse can do is separate the projects into different workspaces, so I can simply start Eclipse with the workspace containing my Maven projects in the production patch branch or the trunk depending upon what I need to be working on.
I'd love to accomplish this in NetBeans, but haven't found a way to do so. Any ideas?
I am using Mac OS with version 6.7.1.
There is the option of project group.
In File > Project group.
In here you can create a project group based on a folder location, so any projects underneath this folder will be considered within this project group.
When switching between project groups only projects within are displayed, and it maintains the current status of opened files, etc.
Switching between project groups doesn't require closing the IDE.
Given those options I believe this would be equivalent to the workspace switching in Eclipse.
I've found two things:
First there is a "similar" feature. It involves using the userdir switch on the command line. The downside being you would need to restart your IDE rather than switching while open. I think I can live with that for the time being. I found the technique here for Windows:
Create a shortcut on your desktop to the Netbeans executable: C:\Program Files\NetBeans x.x\bin\netbeans.exe
Right-click on the shortcut and click "Properties".
In the "Target" textbox, add the extra parameter to the very end: --userdir C:\path\to\new_workspace
Click "OK" to exit the Properties window and double click the shortcut. Netbeans will launch and create/load the workspace at that location
Secondly, someone has submitted a feature to allow for workspace switching (or in this case userdir switching) from the IDE itself. Perhaps this will be rolled into 7.0.
Well Netbeans has a group so you can create a group of projects which you want to say put in a eclipse workspace otherwise.
So when you switch a group it's like switching workpsace in eclipse
I know, that this question is old, but I found it on google, while I was searching for a tool like the following:
http://plugins.netbeans.org/plugin/20677/project-group-toolbar
With that plugin, you can load different projects in your projects overview.
So you can have two or more projects open and change to another "set" of projects.
Neither projects or project groups do not work in a similar way as an Eclipse workspace (yet) as far as I know. When switching workspaces in Eclipse, all the files opened will be closed and the ones in the new project will be opened. In this way, all projects work as one entity. The netbeans project/project groups do not work in that way. I hope there will be such a feature soon cause that really helps if you have many windows open and you switch between projects
I'm looking for solution and finally use Project Group solution, this feature has been improved and easy to use.
Userdir is a good solution at first (i tried to use it first), but "workspace switching" feature doesn't exists, so I have to use different shortcut for different workspace. Finally I used Project Group
NetBeans' equivalent is the "Project". In your project explorer you can right click on the current project and close it. Then go to File > Open Project and select a different branch. You will have to create a new project from each branch of your code.
