Permission denied when using mvn cobertura plugin

Question

I'm using maven to build my project and cobertura for UT code coverage collection. My problem is when I try to build the project, I met the error below, finally I found the failure is caused by cobertura plugin when I was issuing the command : mvn cobertura:instrument.

[INFO] Unable to obtain CommandsFile location.
Embedded error: Permission denied

I tried to go through the directories and I think I have the permission. Have anyone ever seen the failure before? How to debug it?

I think your current user doesn't have write permissions to the temporary folder (check java.io.tmpdir system property value):

The error said the user of java process has no write permission on temp directory (/tmp).

Java process will write pid to a file on the temp directory.

Jps/jstat can use this pid file to get jvm informations.
