I recently updated Eclipse, I have a project in RTC (Rational Team Concert).
When I open my workspace it says all my files are missing.
When I double click on a project I get: No file system is defined for scheme: sourcecontrol
The kind of error message is typical of a faulty installation/update of RTC on top of an Eclipse Distribution:
Could not create the view: com.ibm.team.process.rcp.ui.teamArtifactsNavigator
This thread only offers one solution:
I finally got it fixed by doing a fresh install of RSA 7.5.4 and installing RTC 220.127.116.11 client on top of it.
In your case, one way would be to make a new installation of your Eclipse Distribution, and try installing RTC on top of it, to see if the issue persists.
