eclipse: Managing projects - eclipse

I have tried to find these out, but could not.
Can eclipse open all dependent projects? I have a maven project with dependencies. Can eclipse open dependent projects also? (or at least try to, as some of the dependencies are external and would have no sources/project)
As a workaround to the above possible limitation in eclipse, i have created working sets and added projects to them. But could not see an option to open all projects in a working set one one shot. Is there such an option?
(Using eclipse Kepler)

Selecting this option should do it for you.
mark all project, right click and select open project

maven integration in eclipse new project checked out but can't navigate

I am struggling with maven in Eclipse even though I have m2e.
I checked out a maven project from CVS and cannot navigate anywhere. If I try References > Project, I get a pop up saying:
"Problems opening an editor Reason: services does not exist".
services is the name of the main project, which has sub projects within it. It all builds successfully so I am not sure why Eclipse does not work.
I suspect something related to classpath but have no idea how to edit it since it is not available from the project's properties. I actually tried to manually create a .classpath file but it did not help.
I also converted the project to a maven project but that did not help either.
Any ideas? I am using Eclipse JUNO.
I figured out my issue. I had to check out the project from CVS. Then (that's the important part), perform a maven import of an existing project within eclipse. That created maven "ready" projects where I could use all of the IDE's functionality.
Yes, you're right. If you import directly from a repository, hovering, linking and opening declarations isn't gonna work. Your solution is right, although another one more direct is use the "File->New->Other->Maven->Checkout Maven Projects from SCM". If then, you have problems because you can't select any SCM type, check Checkout Maven project from SCM - no connectors. If with connectors installed you still have problems: http://forum.springsource.org/showthread.php?102665-SCM-types-not-available-in-Checkout-Maven-Projects-from-SCM.
If you have checked out project from svn, project checked out is not generally a eclipse project thats why general functionality of eclipse does not work for the same.
To achieve the same functionality of eclipse like eclipse reader and all other shortcuts,we have to convert the checked out project to eclipse project.
Steps to Convert checked out project to eclipse project:
Right Click on Checked-out Project.
Point to Configure.
Click on Convert to Maven Project.(if checked out project is maven project)
These steps will convert the project to Maven project.
All the eclipse functionality will work for the same.
In addition to ensuring that the projects are configured as Maven projects, you may also go to Project Properties (right-click on the project in Package explorer) > Project References, and add projects in the workspace that the selected project may have references to.
I had this problem, too.
It looks like after a search-in-workspace Eclipse opened a wrong file.
I pressed Strl+Shift+H (Open Type in Hierarchy), typed in the class name, and opened it. The file opened in a new tab, and everything was navigable again.
The difference in icons is:

question from Eclipse

always when I open some project(which already exists) in eclipse I get this question
should referenced projects also be opened where applicable
what does it mean, thanks in advance
You can define dependencies between projects in your workspace. Go to a project's properties and then to "Project references".
Using this feature only makes sense if projects are connected to each other. For example if you have different Django sites and you have one project for each installed app. When opening the site project, you could have Eclipse automatically open the apps projects, too. (For want of a better example...)

What happened to the "Enable Nested Modules" option in m2-eclipse?

I contribute to and implement some open source projects that use a Maven2 build system organized into several sub-modules. I've also been an Eclipse user for several years. With these projects, I have historically leveraged the maven-eclipse plugin so that Eclipse can correctly recognise library dependencies in my project.
It used to be the case that -- when I set up a new workspace or project -- I would have to right-click select "Enable Dependency Management" followed by right-click "Enable Nested Modules." Once I did these things, maven & eclipse would find dependent libraries properly in my .m2 local repo.
But in my most recent install of Eclipse/m2-eclipse -- Eclipse Build 20100218-1602, m2-eclipse 0.10.0.20100209-0800 (sorry, the "About" dialog doesn't provide anything better than that) -- the "Enable Nested Modules" option is missing. Nor does the project seem willing to find my nested modules without it.
After much digging and some trial & error, I got the IDE to recognize my sub-modules by setting...
includeModules=true
In my org.maven.ide.eclipse.pref file manually.
But my question is: what gives? Why did this option disappear? Is there some newer, better way that I should be using m2-eclipse to find nested modules? How are other Maven & Eclipse users dealing with this issue?
The thing here is the option to enable nested modules was moved to the Window >Preferences > Maven. Set the Support multiple Maven modules mapped to single Eclipse Workspace project checkbox, right click your project, navigate to Maven menu item you can find the 'Enable nested modules' option.
Looks like support for this feature was recently removed:
https://issues.sonatype.org/browse/MNGECLIPSE-2291
Why did this option disappear? Is there some newer, better way that I should be using m2-eclipse to find nested modules?
Could this be somehow related to the option below (accessible via Windows > Preferences > Maven):
To be honest, I'm not 100% sure because I don't create my projects under Eclipse, I create them on the command line outside Eclipse and import them as Existing Maven Projects (and this works with nested modules).

Is there a NetBeans equivalent to Eclipse's Workspace

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.

How do I configure Eclipse to work on Qt-based applications in a subversion tree?

Most of the work being done at my company is Qt-based C++, and it's all checked into a Subversion repository. Until now, all work on the codebase has been done purely with nano, or perhaps Kate. Being new here, I would like to take advantage of setting up Eclipse -properly- to edit my local copy of the tree. I have the CDT "version" of Eclipse, and the Qt integration, and the Subclipse module. At this point, though, I don't know what to do. Do I "import" the projects into an Eclipse-controlled workspace? Do I edit them in place? Nothing I've tried to do gets Eclipse to recognize that the "project" is a Qt application, so that I can get the integration working.
I would create a new QT project in eclipse, then switch perspectives to subclipse and simply do a SVN checkout into the new eclipse project. You should be good to go.
OK, I've been playing around with this idea, and it has some merit. I can switch to the "SVN Project Exploring" perspective (which I hadn't noticed before), and do a checkout from the head of the sub-project I want. I get a nice SVN-linked copy of the tree in my Eclipse workspace for editing. Eclipse even "understands" the classes, and can do completion on methods and such. However, I still can't get Eclipse to understand that the project is a "QT Gui" project, such that I could view the properties, and control the linking of the various Qt libraries and the like. By extension, it also doesn't understand how to build my project, like it would be able to do if I had created an empty Qt Gui project from scratch. How do I get this part working?
I have exactly the same situation at work (with CVS instead of subversion and the rest of the team using KDevelop but that's no big deal). Just start a new Qt Gui project using the Qt - Eclipse integration features and then remove all the auto generated files. Now using the "Team" features of eclipse and choose to share your project, enter the path to the repository and you 're good to go.
Checkout the project. It will ask you some options like if you want to start with a blank project, or want to use the tree to make a new project. Choose the latter and you should be ok :). It seems to work for me with Ganymed and subversive(not sure about subclipse and i don't remember.) :)
The only way I could get this to work was to check out the project with eclipse and then copy over the .project and .cdtproject files from another Qt-project. Then do a refresh on the project. This is a horrible hack but it gets you started.
You might need to define another builder for 'make'.
Second nikolavp - Checkout, and mark the option to use the new project wizard, then select Qt project. I've done this (with ganymede) and it successfully finds everything and builds correctly.
My solution:
go to the svn-view and add the repository location for your project
check out the project some temporary location with svn or any client you like
choose 'File->Import...' and say 'Qt->Qt project'
browse to the location of the *.pro file, select and hit the OK-Button
you are in the game with an appropriate Qt-project and Subversion Access for that project
I would say the same as the last one,
but instead of the two first steps I would set up the Qt-Eclipse integration:
Qt-Eclipse integration before looking for the *.pro file.
