[JENKINS-11739] Cannot compile a plugin with a Plugin subclass in the same package as a package-info.java.
(Not quite FIXED yet since org.kohsuke.stapler.jsr269 seems to suffer from a similar bug, currently printing ugly warnings.)

[FIXED JENKINS-13916] Text parameters are now defined and shown in a textarea instead of a one line textbox.

Update transient action after config submit, as trantient action may change due to change of view properties.

Seems to be due to hetero-list.jelly importing repeatableDeleteButton.jelly but nothing on the page loads repeatable.js.
(Presumably worked for /configure just by accident because someone else included repeatable.jelly on the same page.)

Not yet clear to me exactly what went wrong, but debugging shows that the init(...) function
is called twice: once with legitimate arguments, then again with a bogus 'master' argument.
Seems to suffice to ignore redundant initializations of the same element.

When selecting one plugin, find all other of the same type, and make sure that check box is toggled too.

Add @Exported annotation to the executor of a Run to have more information on a running Job via the remote API

This is based on https://github.com/jenkinsci/jenkins/pull/521

I'm not entirely sure if the reparse point should be considered the same as symlinks, but I'm merging this anyway.

If the user has an earlier Jenkins installation,
we should probably change the jenkins user shell
during the upgrade.

If the user has already changed jenkins user shell
to something else, we do not touch it.

notify user some results have been truncated
provide link to get more results

Uninstall.command is dropped to /Library/Application Support/Jenkins

Used xmllint --format

Noticed via failure in BuildCommandTest.testConsoleOutput.
