Today I was fighting some really annoying behaviour of Eclipse in combination with refactored multi module maven projects.
Whenever I tried to import the projects, I recieved the error
An internal error occurred during: "Updating Maven Project". java.lang.NullPointerException
I tried to solve the problem by removing my eclipse projects and cleaning all eclipse related files, but that didn’t work. For some reason mvn eclipse:clean refused to delete my files. Thus I had to find a way to recursively delete all eclipse related information from my project. So here it is:
find . -name .classpath -exec rm -rf {} \; find . -name .project -exec rm -rf {} \; find . -type d -name .settings -exec rm -rf {} \;
