When run via Jenkins pipeline, if a Gradle task fails or Gradle exits with a non-zero exit code, this line swallows the error message:

https://github.com/jenkinsci/artifactory-plugin/blob/master/src/main/java/org/jfrog/hudson/pipeline/steps/ArtifactoryGradleBuild.java#L184

This makes it extremely difficult to troubleshoot failed builds, especially as you start to mix in other things like the Docker plugin, etc. Reproducing the build is not trivial.

The full error details should be displayed in the Jenkins console log.
