When I try to start Eclipse Luna in CentOS 7, I get the following dialog box:
How can I resolve this and get eclipse to start?
I removed .metada from workspace and reimported the maven projects as quick and dirty solution. You loose your Eclipse settings, you can try to play with metadata.
Instead of deleting the whole .metadata folder, just delete the file .metadata/.plugins/org.eclipse.e4.workbench/workbench.xmi" You need to make sure to quit eclipse first, then remove this file and start eclipse again.
Error will be gone.
For me it was enough just to remove the whole <persistedState /> tag in
<workspace folder>/.metadata/.plugins/org.eclipse.e4.workbench/workbench.xmi 来源：https://stackoverflow.com/questions/31080665/eclipse-wont-launch-because-reload-maven-project-has-encountered-a-proble
