I have a new Jenkins installation (deployed in Tomcat), and I defined the Jenkins home directory to:

/srv/webapps/jenkins

Maven Jobs seem to not be able to deal with this (even though it is the home directory defined in the configuration).

They also don't respect the <localRepository> definition in the global settings.xml file.

Below  is a Test case that I ran.

Would you be able to help me confirm if this is a bug (so it can be reported), or point me in the right direction if it's not?




1. Create Maven Job 
2. Goal: verify 
3. Global settings file: Provided Global Settings: MySettings (which has <localRepository>/srv/maven/.m2</localRepository>)
4. Run Job. Result:
