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?
Project -> Maven -> Update Configuration. RELEASE. Open a brand new project, put only (like this) <dependency><groupId>org. springframework</groupId><artifactId>spring-core</artifactId><version>3.2. 2.
If you for example change important plugin settings, such as the output java version, you will find that Eclipse will ask you to update the project and afterwards the configured Java runtime in the project will have changed to reflect what your Maven pom indicates.
Right click your project and Run as -> Run Configurations... Add the -e (or other switches for eg. -X, etc.) in the Goals input box.
You can usually resolve these errors by updating Maven dependencies as follows: Right-click on your top-level project (not on the pom. xml file) in the Project Explorer view. From the menu, choose Maven > Update project.
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.
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.
For me it was enough just to remove the whole <persistedState />
tag in
<workspace folder>/.metadata/.plugins/org.eclipse.e4.workbench/workbench.xmi
