checkExit
public void checkExit(int status) Always throws aSystemExitException
whenSystem.exit(int)
is called, instead of terminating the JVM.The exception is meant to be handled in the
exec:java
goal. On the one hand, this avoids that Java code called in process can terminate the JVM and the whole Maven build process with it. On the other hand, the exception handler can also differentiate between exit status 0 (OK) and non-0 (error) by inspectingSystemExitException.getExitCode()
:-
Exit status 0 (OK): Just log the fact that
System.exit(int)
was called. - Exit status non-0 (error): In addition to logging, the exception is also passed on, failing the mojo execution as if the called Java code had terminated with an exception instead of trying to terminate the JVM with an error code.
