Could not load Logmanager

It’s suspicious that the Gradle wrapper gets installed into ‘opt/tomcat’. I don’t know why that would be happening, but I do know that the Jenkins Gradle plugin used to set strange Gradle user homes. From what I’ve heard, this has been solved in recent versions of the plugin. So first thing I’d do is to upgrade to the latest Jenkins Gradle plugin.

Peter,

I’ve been doing some more research and I think the problem might have more to do with Tomcat than with the gradle wrapper. Non-gradle users are having this same problem. Apparently, setting the JAVA_HOME environment variable correctly for our Tomcat server might fix the problem. FWIW, “/opt/tomcat” is the home-directory of our Tomcat installation.

I’m using the wrapper from gradle 1.6.

I understand what ‘/opt/tomcat/’ is, I just don’t understand why the Gradle wrapper’s Gradle distribution gets installed there.
