Here’s a very weird Maven/Java issue. The error message (below) occurs in my build phase where JaxB is called to produce some Java objects from XML. JaxB calls HyperJaxB, and on some systems it crashes.
[ERROR] XJC while compiling schema(s): org.apache.commons.logging.LogConfigurationException: org.apache.commons.logging.LogConfigurationException: org.apache.commons.logging.LogConfigurationException: Class org.apache.commons.logging.impl.Log4JLogger does not implement Log Caused by: org.apache.commons.logging.LogConfigurationException: org.apache.commons.logging.LogConfigurationException: org.apache.commons.logging.LogConfigurationException: Class org.apache.commons.logging.impl.Log4JLogger does not implement Log Caused by: org.apache.commons.logging.LogConfigurationException: org.apache.commons.logging.LogConfigurationException: Class org.apache.commons.logging.impl.Log4JLogger does not implement Log Caused by: org.apache.commons.logging.LogConfigurationException: Class org.apache.commons.logging.impl.Log4JLogger does not implement Log
But not all. My main dev machine works, my deployment machine doesn’t. My other deployment machine also works, but dave’s machine doesn’t. All of us are using the same Maven version (2.0.8), mostly the same Java versions (1.5.0_xx), and some are amd64, other are x86. However, the crash/work divide does not fall on this line. In fact, on the deployment machine both local users can compile OK, but the LDAP users can’t.
On Dave’s machine if we move the local repo to /tmp (-Dmaven.repo.local=/tmp/repository) it starts working. I did capture the class path on a few occasions, and it seems to be in quite a random order. I noticed that commons-logging is far closer to the start of the class path when the compile works, but I don’t have enough samples to confirm this.
Another curiosity I saw was that if your home directory is in a non-standard place, like /var/home/, then maven puts your repository in a directory called ? in the current working directory. Thats right, question mark. Oh dear.
