Bamboo shows a failed Maven2 build as a successful one. It is probably something to do with how many lines is read from the Maven log to recognise the failed build. Whenever there are some missing dependencies and "cannot resolve symbol" errors, they are shown after "[ERROR] BUILD FAILURE" line and that may cause the incorrect behaviour.

This problem should be easy to reproduce by creating a few objects in Java code but leaving all the necessary dependencies out of pom.xml.

Notice also that "The build will produce test results." flag must be turned OFF to show off this bug.

When "The build will produce test results." flag is turned on the build fails as it should.

A used Maven command was:
mvn clean install --batch-mode

Here is the log:
