I'm having major issues with getting Hudson up and running on a gentoo server with Tomcat 6. I'm able to deploy Hudson just fine, and I can browse the web-application, configure it and set up builds etc.
However, when I try to run a build (in example "clean test" on a Maven2 project) I get this error
ERROR: Failed to create /dev/null/.m2
I've google'd and for some it seems to be helping to put -DHUDSON_HOME=/home/hudson and -DMAVEN_HOME=/home/hudson in /etc/init.d/tomcat-6's JAVA_OPTS. However, I've tried that and by doing the same in /etc/conf.d/tomcat-6 , but I'm still getting this error.
Has any of you had to deal with this before?
You are likely running Hudson under a special user. Try setting the home directory of that user to /home/hudson in /etc/passwd using the vipw
command.
Another way would be to disable user level config with your $M2_HOME/conf/settings.xml
but Jouni's solution is the better choice.
