Version: Mars.1 Release (4.5.1) Build id: 20150924-1200 Team->Share Project causes null pointer exception. Project itself is located on a Remote system (created via "Create Remote Project" on Remote system Explorer). I suspect this is the cause of the bug. Error log below: !ENTRY org.eclipse.jface 4 2 2015-11-13 12:37:45.417 !MESSAGE Problems occurred when invoking code from plug-in: "org.eclipse.jface". !STACK 0 java.lang.NullPointerException at

(In reply to Ed Darnell from comment #0) > Team->Share Project causes null pointer exception. > > Project itself is located on a Remote system (created via "Create Remote > Project" on Remote system Explorer). I suspect this is the cause of the bug. The immediate cause of the NPE is that EGit uses the location of project, not the locationURI. So if a project is located on an EFS, we'll get that NPE. AFAIK, the RSE uses an EFS to map the remote system. However, the problem goes deeper: to "share a project", EGit moves it into the git working directory of the git repository. The javadoc of IResource.move() states that it'll raise a CoreException if the resource or one of its descendants is non-local. So I suspect even if the immediate issue was corrected, we'd just run into a CoreException during the actual move. @Ed: is it possible to move that remote project to the local file system at all? Perhaps the whole operation should not be offered by EGit for non-local projects. See also http://help.eclipse.org/mars/index.jsp?topic=%2Forg.eclipse.rse.doc.user%2Ftasks%2Ftusingefs.html: "Pure RSE/EFS projects (i.e. where the .project file is on the remote system) are currently not supported due to low-level interactions between EFS, the Eclipse platform, and the RSE caching mechanism. Purely remote projects will not open automatically on Eclipse startup. However, one can link lower-level folders of a project to an EFS provider, allowing a project to contain a mix of remote and local resources. Note that team support (such as that provided by CVS) will not synchronize resources linked through an EFS provider at this time."
