Question

I need to run a java application, if its output is “Passed” then I will run mvn site command. I have gone through several forums and got to know this can be done using pre-site goal but how will i validate the “Passed” state. The Java Application is a command that is used to invoke a Python script. If it runs successfully then output is passed. If i run from Hudson I can put the command in Pre-Build Step. But How will I validate if the output is passed or failed. Please help

From Jenkins’s ‘Execute Shell’ help:

the build is considered a failure if any of the commands exits with a
non-zero exit code.

So you should make the Java application return 0 if passed, and something else otherwise. You can use System.exit(0) for that.

If you have no control over the java application, you can use tail -1 | grep Passed to see if the command had “Passed” in its final line.
