And every log file found on workspace ends the same way.

But running

../../../tools/maven/bin/mvn install

from a prompt, inside

/var/lib/jenkins/jobs/visualligence/workspace

outputs a full error trace with the compilation errors that can help to solve the problem:

How can I tell jenkins I do want that error trace?

Answer 1

for this there are two possible ways to find out where your problem is:

1. add -Xdebug to your MAVEN_OPTS set MAVEN_OPTS=-Xmx1024m -Xms1024m -Xdebug call mvn clean install
2. Or look for the failure via remote debugging. For this add the "maven-compiler-plugin" to one of your eclipse projects and start the maven build on your broken project with set MAVEN_OPTS=-Xmx1024m -Xms1024m -Xdebug -XX:PermSize=256m -Xrunjdwp:transport=dt_socket,address=4000,server=y,suspend=y call mvn install Than start a remote debug session in eclipse and add a "error" brake point to "CompilationFailureException" this will figure out your problem immediately.

Wish you much luck for it

Answer 2

mvn --help lists down options you can use with mvn command.

-e,--errors     Produce execution error messages
-X,--debug      Produce execution debug output 
-q,--quiet      Quiet output - only show errors

Should you not be using maven with -e option to track down errors in jenkins job configuration.
