why hudson failes the maven test build

I have one TestNG test in my project. When I run it from command line with mvn integration-test it says:

Running TestSuite Testing ... Tests run: 1, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 0.29 sec

Results :

Tests run: 1, Failures: 0, Errors: 0, Skipped: 0

After I create a build in Hudson of type Build a Maven 2/3 project (Legacy). In goals I say integration-test. In the end I do Build now and then what I see in Hudson console output is:

Did anybody counter the problem and could write how it was solved. Thank you in advance.

Are you using multiple threads? There is a Fixed issue on Jenkins that was causing this failure regarding multi threads:

https://issues.jenkins-ci.org/browse/JENKINS-9183

Also, are you using Jenkins or Hudson? Have you consider migrating to Jenkins?

Please refer to:

https://wiki.jenkins-ci.org/display/JENKINS/Upgrading+from+Hudson+to+Jenkins

That will solve many issues that are fixed on Jenkins. Maybe you can try doing a POC for this and then propose moving Hudson into Jenkins.
