I am trying to export an Xtext project as an Eclipse Product. The launch configuration works flawlessly if launched from within Eclipse, but I am unable to export it to make a self-contained product. I get:
An error occurred while collecting items to be installed session context was:(profile=profile, phase=org.eclipse.equinox.internal.p2.engine.phases.Collect, operand=, action=). Problems downloading artifact: osgi.bundle,org.eclipse.sdk,4.2.0.v201206081400.
org.eclipse.sdk-4.2.0.v201206081400 is already imported as project in the workspace. I'm trying to export using "all workspace and enabled target plugin" rather than selecting the plugins one by one.
I'm on Linux 64bit (Sabayon).
