Your project contains error(s), please fix it befo

Answer 1

I had similar problem where I couldn't run my project yet didn't see any problems in the code. In Error Log panel it said something like "Cannot add P/ to the list of segments P/ in as a parent". Restarting Eclipse solved the problem.

Answer 2

I saw this with an existing project. I had made a few edits, but hadn't imported anything new. Restarting Eclipse didn't help.

Project->Clean did solve the problem.

Answer 3

I come across this error often when I import a new project in my workspace.

Reason: Some necessary files (Like R.Java) is not generated in its respective packages.

Cure: Clean and build projects, All the files that needs to be auto generated will be there on place after building the project.

Best Luck.

Answer 4

This happened to me when I was experimenting with Maven.

Right click project -> Maven -> disable maven nature corrected the problem for me.

Answer 5

Simulate your self some error in class. Then save it and it would show more errors than you simulated. For me it was incorrect import and this helped.

Answer 6

Try changing your workspace. I am not sure this is the exact solution . I did face the same issue for sometime untill i changed my workspace.
