• Batch Mode

  (from Maven Continuous Integration Best Practices (see above):

  Enable -B (batch) mode on the build. This will make the logs shorter since it avoids the dependency download progress logging.

• Local Repository

  (from Maven Continuous Integration Best Practices (see above):

  Use -Dmaven.repo.local=xxxx to define the unique local repositories for each build.

• Snapshots

  Enable -U to cause Maven to always check for new snapshots.

• Stack Trace

  (from Maven Continuous Integration Best Practices (see above):

  Enable -e to cause Maven to produce the full stack trace if there’s a build exception.

• Test Output

  Enable -Dsurefire.useFile=false. This is a favorite of mine since this causes surefire to print test failures to standard out, where it will get included in the build failure log and email. This saves you from having to dig back onto the machine to find the surefire report just to see a simple stack trace.
