The fix for
WAGON-465 unfortunately broke backwards compatibility with version 2.10 when using maven-site-plugin together with wagon-ssh. The first commit had correct code for backwards compatibility, but that commit was reverted. The next commit did not include the correct code for backwards compatibility.
When using wagon-ssh with maven-site-plugin the call to AbstractJschWagon.executeCommand() is done with the one-parameter version of the method. That method sets the new parameter ignoreNoneZeroExitCode to false, which results in the exit code being checked. Before
WAGON-465 the exit code was never checked, it was only written to the log if there was an error message.
For us the site-deploy succeeds with wagon 2.10 but fails with 2.12 and 3.0.0. It seems that the last chmod command returns 1 for reasons yet unknown, but it outputs no message to stderr.
I will try to investigate why chmod returns 1 and I'll create a patch that restores the compatibility with version 2.10.
