How to fix Failed to execute Goal org.codehaus.mojo:exec-Maven-plugin:1.2.1:exec error?

Question

I’m making that mistake:

------------------------------------------------------------------------ BUILD FAILURE ------------------------------------------------------------------------ Total time: 3.454s Finished at: Sat Jul 23 11:47:20 BRT 2016 Final Memory: 11M/172M ------------------------------------------------------------------------ Failed to execute goal org.codehaus.mojo:exec-maven-plugin:1.2.1:exec (default-cli) on project csv-to-rdf: Command Execution failed. Process exited with an error: 1 (Exit value: 1) -> [Help 1]

To see the full stack trace of the errors, re-run Maven with the -e switch. Re-run Maven using the -X switch to enable full debug logging.
