After update, everything got messed up in eclipse-java(on linux manjaro). I get errors every time i try to create a java project or import from SVN. The error mostly is:

"An error has occurred. See error log for more details.
java.lang.NullPointerException"

Any ideas what to do?

Is this a package of your distro? Better just download eclipse manually.

Try this:

- Open the error log view. (Window->Show View->Error Log)
- Clean the log (there is double x in its toolbar)
- Create the project
- Double click on the error that should appear in the log
- Copy the contents of the stack trace dialog and paste here.
