Jenkins permission problem.

[Brian Jakovich]

I seem to be having a permissions problem with Jenkins.


## Background

I am running Jenkins ontop of Tomcat 6.
I set my JENKINS_HOME using JAVA_OPTS="-DJENKINS_HOME=/var/lib/jenkins -Xmx512m -Djava.awt.headless=true"
Both my jenkins/ folder in my tomcat webapp directory and my jenkins_home folder are owned by the tomcat6 user and the tomcat6 group. They are both chmoded to 0644 aswell

## Error

hudson.util.IOException2: Failed to create a temporary file in /var/lib/jenkins

Any help would be appreciated

You need execute permission to cd into a subdirectory:

chmod -R the dirs to 755 and you should be OK.
