I have a GMF editor and an Acceleo UI project that I would like to bundle in a single plugin. That's not the matter though.
You see, when executed in the runtime (Run as > Eclipse Application), both the GMF editor and the Acceleo UI project work fine and dandy.
However, when exported as plugins and installed into Eclipse, only the GMF editor will work. The Acceleo UI item WILL show up in the context menu, and it will create the target folder for the files. But this folder will be empty.
Is there a reason why one plugin would work properly while the other does not? Is there any additional configuring that must be done in the Acceleo UI for it to work outside the runtime?
Searching the Eclipse Forums, I found something about adding a line 'outputFolder="${target.folder}"' to a file "acceleo.build", but I can't find neither the file nor the line anywhere.
Any help would be greatly appreciated. I'm working on Eclipse Mars with version 3.6.3.201602090916 of Acceleo.
So, I know nobody ever replied to me, but I found out the problem so I might as well post it in case someone runs into the same issue in the future.
The issue was that Acceleo needs a file with extension .emtl to work. This file wasn't showing up anywhere when exporting the plugin, though. I thought it was failing to compile it (as the .etml is actually a compiled form of the .mtl file).
After some digging, I found out Acceleo does actually create said file, but it doesn't put it in the same place where the .mtl is - it actually places it in a folder called "bin", which isn't created by default when exporting the plugin. In order to see this "bin" folder, I had to mark it in "Build Configuration", in the build.properties file.
Then, I manually copied the .etml in "bin" to the plugin's "main" folder (where the .mtl file resides) and that was it, it worked like a charm.
I hope it's OK to ask this here. Netbeans forums isn't responding. If not, I'll delete this or ask for it to be deleted. I'm desperate so I'll face the wrath, if any.
I moved my Netbeans projects folder from one directory node to another to make backing up all my stuff easier. BAD MOVE.
Now when I open a project using Files | Open project (ctrl-shift-O) NO source files appear because there is no "+Source Packages" node to expand.
It looks like this for all projects, e.g. one named GBL:
Projects
-GBL
+Libraries
It doesn't look like this anymore:
Projects
-GBL
+Source Packages (How do I get this back?)
+Libraries
The Netbeans Properties for each project shows me the path it's using. Windows 7 Explorer shows me that the src, build, and nbproject folders contain files and ALL the source files are in the src folder for that path.
What have I done and more importantly what should I do to get back to being able to open a project normally?
(I've tried recreating the original Netbeans folder and using Windows Explorer to copy an entire project folder into it but: same result--all I see is the Libraries node under the project's name node.)
I just tried to Clean (and also Build) to see what would happen. Error:
ant -f C:\\Users\\Dov\\Documents\\NetBeansProjects\\BasicShirt -Dnb.internal.action.name=build jar
C:\Users\Dov\Documents\NetBeansProjects\BasicShirt\nbproject\build-impl.xml:[u]231[/u]:
Must set src.dir
I just Set Configuration by right-clicking the project's name and provided a path to the src folder.
NOW I SEE MY SOURCE FILES BUT NOW THIS line in the .xml file is flagged with similar message:
<fail unless="[u][b]test[/b][/u].src.dir">Must set test.src.dir</fail>
NOW what do I do? (Netbeans 7.4.)
If I could get rid of the 7.4 automatic creation of +Test Packages, I might be OK.
If you can help, I'd be very happy.
(I'm considering re-installing 7.3 if available or removing and reinstalling 7.4 and try to avoid the "testing" requirement, but there goes all my many tweaks of 7.4.)
Well, after considerable frustration with the problem, I solved it, essentially.
It's here, in total. My synopsis plus how it helped me follows. In short, I had to set up a new java project based on existing sources using the New Project Wiz and simply direct Netbeans to the sources.
File > New Project
Choose Java Project with Existing Sources.
Type a (new) project name and ...
... make the Project Folder contains the path to where you want the new project to be stored. (For me, this is the folder where Netbeans has been able to find my sources.)
Click Next for the Existing Sources page of the wizard and ...
5a. ... in the Source Packages Folder pane, click Add Folder and ...
5b. ... navigate to your sources and select the source root folder.
Clicking Next goes to the Includes/Excludes pane, which I didn't need to use.
I have lost files mysteriously a few times from my Eclipse workspace folder, and previously I assumed that I must have deleted them, but this time I know for sure that I didn't.
I entered a folder for a Java project. I listed the files. There were several text files. I then opened one in gedit to look at it. As far as I remember, I then did something in libreoffice Calc (to a spreadsheet file in a completely separate location), then I made some changes to the Java file in Eclipse. It would then have been automatically compiled. I then went back to the terminal to execute the program, but it wouldn't run. Listing the files shows that the reason it wouldn't run is that all the text files have disappeared and so has one of the .jar files (called stanford-parser.jar) but not another. I've searched my computer for these files and I can confirm they've gone.
A screenshot from my terminal illustrates this.
Can anyone help me to understand how this is happened, so I can avoid it happening again? Could compilation delete the files?
You seem to be storing source files in the bin directory of your Eclipse project, which is probably the target directory used by Eclipse to put the compiled classes. Store your sources in the source folder. The target folder is completeley deleted by Eclipse each time the project is cleaned up.
Note that non .java files stored in the source directory are automatically copied to the target directory by Eclipse. They're considered as resources that must be available at runtime in the compiled application.
I am using Eclipse IDE to write code in PHP, but I used NetBeans, which is also a very good editor!, However, I came across a doubt, NetBeans, when I created a new project, it generated an nbproject folder, with figures from the netbeans, of course, are the project settings, since the eclipse, generates files in the root directory of the project, I wonder if I would do this with eclipse, when I create a project in eclipse, create it creates a directory named 'ecproject' and play the files '. buildpath', '. project', '. settings' inside this directory, so it looks organized application folder. Thank you all!
You can't. This has been discussed quite a long time ago at Eclipse (see https://bugs.eclipse.org/bugs/show_bug.cgi?id=76695, https://bugs.eclipse.org/bugs/show_bug.cgi?id=42875 and https://bugs.eclipse.org/bugs/show_bug.cgi?id=72301)
The last one contains an interesting suggestion, though: Create another project for the .project-Files and just link your sources into that one.
I've installed NetBeans 6.9.1 and installed few updates for it.
Then I've created a new project from existing sources. After a few changes I've closed it. And now I am having an error, when trying to open a new project from existing sources (the same files):
Sources directory is already netbeans project (maybe only in memory).
After Googling it, I noticed it happened not only with me. But I didn't find the correct solution. I've tried to restart the IDE, I've tried to restart the PC, I've tried to reinstall NetBeans. Nothing helped.
Thank you!
I was having the same problem:
Sources directory is already NetBeans project (maybe only in memory).
Netbeans creates a folder in your project named "nbproject". Once you delete that, restart the IDE and you're good to go.
When you create a NetBeans project from existing sources, NetBeans uses the same directory to add its own files: a netbeans folder with .proj files.
Solution: delete the netbeans folder and restart the IDE. Opening a new project should now work.
Go to the folder containing your project
Delete the folder named nbproject
Restart Netbeans
Try creating your project again from the original folder
This means the project folder is already a netbeans project. So instead of adding it as a new project open it as
This happens(i believe) because netbeans tries to version control the files created or edited.
Under the project folder netbeans create a netbeans directory just delete it . This has been tested in Ubuntu. Then you can import your project if php then php using existing sources.
Click File >> Recent Projects > and you should be able to use edit it again. Hope it helps :)
On Windows at least none of these answers work (for me anyway!). I have found the only way is to copy an existing netbeans project folder in to your new project and manually edit the xml project name.
I also opened the private/private.xml and removed the open files xml just incase these caused problems.
Once I'd done this the project works as normal.
I checked the "Put NetBeans metadata in separate directory" tick and it works fine.
This is in 2. Name and Location after you choose PHP from existing source
In my case my project root directory consists ".project". This contain the XML reference of the project name.
By removing this, i am able to create a project.
Usually this happened when we copy source code of a already created project and copied in different folder and try to create a project from it. as netBeans create its folder nbproject in our project folder this folder also get copied with our source code and it give error "Sources directory is already NetBeans project (maybe only in memory)" remove this folder from you newly copied folder and voila you can create a new project.
If this is your own source code and you already have a Netbeans project folder with your source files you should just start with:
File | Open Project...
not
File | New Project ...
because the project is not new.
If it helps anyone else, I had the same problem and the solution was to reinstall NetBeans.
I had tried all sorts of fixes: Deleting the NetBeansProjects folders, checking/unchecking "Put Netbeans metadata in a separate directory", killing/restarting NetBeans, restarting the system, etc. Nothing cleared the message...except the reinstall.
The advice here about removing the nbproject directory is not quite the whole story.
What Netbeans seems to do (and we are guessing at reverse engineering here) is to look for an xml file which has opening and closing project tags in it. This it concludes is evidence of an already existing project. Now if your files have an nbproject directory there, that will contain a project.xml file which contains the said tags. So removing that will do what you want.
But, my files don't have a nbproject directory but still NetBeans tells me there is an existing project maybe in memory. The reason is: my files include a file called pom.xml and that contains the said project tags in the xml (it was created by an entirely different system). Once that xml file is removed, then NetBeans will create an html project for me importing my code.
In sum: look through any xml files in you existing code, and be wary of project tags.
This happened to me when I tried to import an Eclipse project in a brand new NetBeans 7.2.1 install on Ubuntu 12.04LTS.
I mistakenly selected the import projects from workspace (the first option in the import wizard's opening pane) on the first attempt, and it opened the project in the original Eclipse workspace path (which was on a usb stick).
From this, I then realized that I actually need the second option - import project ignoring project dependencies, which lets you specifically choose source and destination folders. After closing the project, I tried to import again with the proper option, but it didn't work.
From then on nothing I did helped - restart the IDE, move the source folder, nothing. There was no nbproject folder in the project or /var/cache in the user folder to delete (in-fact there was no nbproject folder in the whole file-system).
Since restart didn't work, I'm guessing that there is a garbage project entry somewhere which Nb reads (See Martin Frické answer above).
After googling along the lines of 'netbeans clear memory project cache' with no success, I opted to reinstall NetBeans -
sudo /usr/local/netbeans-7.2.1/uninstall
sudo ./netbeans-7.2.1-ml-javase-linux.sh
which solved it.
If you are on a Mac, press command shift G and in the box type /users and then go, next click on your user name and navigate to netbeansprojects and open it. Then delete the ones in there that are causing problems. You can then create your project.
Note: I had moved my wordpress folder to my desktop trying to figure this out, so I dropped it back into the origional location and it works fine. So if you did this, just replace the wordpress folder after deleting the problem projects from the netbeansprojects folder and its contents back to the original installation folder.
Hope this helps...:)
This is what I did to solve this error:
1) I copied a folder named "folder1" (and I called the new folder "folder2"). "folder1" was a Netbeans project so it had a folder called "nbproject" inside it.
2) When I tried to create a project out of the "folder2", Netbeans threw an error "Sources directory is already netbeans project (maybe only in memory)."
3) Inside Netbeans delete the project of "folder1". Then, delete the two folders named "nbproject" (one is inside "folder1" and the other is inside "folder2").
4) Inside Netbeans, create two new projects: one for "folder1" and another for "folder2". The error should not appear anymore.
copy an existing netbeans project folder in to your new project and manually edit the xml project name.
reinstall netbeans
copy/move all files/folders (except nbproject/ folder) to a new folder for your project, with a new name.
Try to create a new empty project; then you can copy the public_html to the new project folder and it will appear .
I faced the same issue:
Sources directory is already NetBeans project (maybe only in memory).
The solution is:
Netbeans creates a folder in your project named "nbproject". Once you
delete that, restart the IDE and you're good to go.
