Answer 1

This solution worked for me.

Close Eclipse and delete all .markers inside your workspace folder.

Restart Eclipse (once I had to restart it twice, it hang on the first but worked on the second for no aparent reason).

Of course, it's always safe to back them up first.

Answer 2

This is just weired. In my case when I took a subversion update, I was getting this problem. The reason was the corruption of my project.properties file (due to subversion conflict). I just corrected the file and problem got solved.

Answer 3

Do not delete all the full .metadata

• Backup .metadata
• delete only .metadata/.plugins/org.eclipse.core.resources/.project
• restart eclipse

Observation : the projects folders are created

Further - if you are using svn/git/hg have code repository links it would be destroyed, so to reinstate

• close eclipse
• copy relevant projects from backup to merge with current projects in .metadata/.plugins/org.eclipse.core.resources/.project
• restart eclipse

Downfall - sporadic fail error may occur (sync or something) - harmless

backagain

Answer 4

For me, the source of the NullPointerException problem was a host-side Junit test project that references (and tests) code from an Android project. It didn't have a project.properties file. It's not an Android project, but for some reason the newer versions of the SDK somehow expects the file there. To fix the problem, I just copied a project.properties file from an Android project to the host unit test project.
