“A configuration with this name already exists” er

问题:

I synced mercurial project, and tried to setup run configurations.

I found the name has (1) attached, and I tried to remove it.

However, I got A configuration with this name already exists error. I checked other configurations, but there was no duplication of Name Equivalence Checker.

How can I find the existing configuration to remove it?

回答1:

uncheck the filter: Filter Deleted/Unavailable Projects

回答2:

There is a chance you have a launch configuration stored in your workspace as file. Use CtrlShiftR to open the "Open Resource" dialog. Start typing "EquivalenceChecker" and see whether it finds a .launch file with that name in your workspace.

Uncheck all filters under dropdown for "Filter launch configuration"; it is there. If a project is renamed the launch configuration is updated. But when a project is deleted the launch configuration is not deleted. Appear to be a useful feature.
