Tip for running Maven2 using Apache Harmony

Just set JAVA_HOME as usual and run “mvn clean install”. But there’s a gotcha. You may see the following issue when surefire tries to run the tests.


[INFO] [resources:testResources]
[INFO] Using default encoding to copy filtered resources.
[INFO] [compiler:testCompile]

If you do, then just set your MAVEN_OPTS as follows and run “mvn clean install” again.


set MAVEN_OPTS=-Dsurefire.useSystemClassLoader=false
