Expecting JavaExec to fail when an exception is thrown by command line application

Help/Discuss

I am using the JavaExec task type to execute a command line application.

When the application throws a Runtime Exception, I am expecting the task to fail, but it passes as successful. Is this the expected behavior?

The output was

.\gradlew validate
Configuration on demand is an incubating feature.
Calculating task graph as configuration cache cannot be reused because file ‘build.gradle’ has changed.

Task :validate
There was 1 error validating the JSON Schema

Ok, after posting I found the problem. With the Picocli library the application does not return a non-zero exit status when an exception occurs. I have overridden that now and the task fails when it should.
