I have created a couple of java working sets for a project in my workspace and want to share them with other people (using different workspaces). Is there a way to export them?
You can try and export (as in "copy to another people workspace metadata directory"):
</path/to/.metadata>\.plugins\org.eclipse.ui.workbench\workingsets.xml
This is the file referencing your working sets.
z0r adds in the comments:
my team mate replaced his
workingsets.xml
with my version of the file, and it worked well.
However, you must exit Eclipse before replacing the file, because Eclipse will overwrite it with the old version when it exits.
I think you only need to do this once.
