configure logback to trace level in junit tests

[Jean-Claude Cote]

I'm trying to output trace information in my junit test cases. I'm using
the ClusterFixture

startCluster(ClusterFixture.builder(dirTestWatcher).maxParallelization(1));

I've put my logback.xml in src/test/resources

and feed in these environment variables at the command mvn launch.

mvn --offline clean install -Dlog.path=/tmp/sqlline.log
-Dlog.query.path=/tmp/sqlline_queries.json

But no output files are created. How can I accomplish this?

Thank you
