When you configure a maven build you can check the option "The build will produce test results.".

If you enable this options and you have failing integration tests in your project, the project will build without displaying test errors.

The standard test directory is

"*/target/surefire-reports/.xml"

The default setting should be changed to

**/target/surefire-reports/*.xml,**/target/failsafe-reports/*.xml

to include results from integration tests too, or another option should be added to include this test results too.
