-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Ole,
In one instance (have to check your mail again) there were no files to compile, so nothing bad happened. If you run mvn clean test, then the target directory will be removed and Maven will be forced to recompile everything. You should get the command line failure consistently then. - From your log that you posted: Warning: JAVA_HOME environment variable is not set. Also, can you run the following from the command line and see if it works? javac -version You should get the version of javac echoed. If not, you have a path problem. If you do, run the following command: which javac This should tell you where javac is installed. I don't know how alternatives / OpenJDK gets installed on Ubuntu (I use Fedora and Oracle's JDK), so I don't know if setting JAVA_HOME to javac's parent directory is appropriate. For example, on my system 'which javac' results in: /usr/java/bin/javac This means that javac is in /usr/java/bin, and the parent directory (/usr/java) is the value that JAVA_HOME is set to on my system. This is actually a link to where the current version of Java is installed on my system. One of these days I'll walk through alternatives and figure out if it meets my needs (or if I should file bug reports). . . . just my two cents /mde/ On 12/31/2014 9:52 AM, Ole Ersoy wrote: > Hi Mark, > > I do have Open JDK installed.
