well, why do you want to have a trailing space here? the text block you current have produces the following multeline sting, which has a trailing space at 4th line:

   - To only run the failed tests use -DTest, -DExclude,
     and/or -DScenarios.

     -DReportStdout=true or for even more fine-grained logging
     use -DVerbose=true.
