to reproduce :

• create a maven project using default archetype.
• setup maven to build it
• change test to fail : `assertTrue(false)`
• jenkins detects test failure

• add build extension co.leantechniques:maven-buildtime-extension:1.0 to pom.xml
• confirm on command line maven still detect test failures :

  -------------------------------------------------------
   T E S T S
  -------------------------------------------------------
  Running foo.AppTest
  Tests run: 1, Failures: 1, Errors: 0, Skipped: 0, Time elapsed: 0.01 sec <<< FAILURE!
  testApp(foo.AppTest)  Time elapsed: 0.008 sec  <<< FAILURE!

      at junit.framework.Assert.assertTrue(Assert.java:27)
      at foo.AppTest.testApp(AppTest.java:36)
  

• run same project on jenkins :

  -------------------------------------------------------
   T E S T S
  -------------------------------------------------------
  Running foo.AppTest
  Tests run: 1, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 0.004 sec
