Since version 2.0, the Mattermost Plugin no longer has a field showCommitList.
This leads to Jenkins finding "unreadable data":
MissingFieldException: No field 'showCommitList' found in class 'jenkins.plugins.mattermost.MattermostNotifier'
Instead, there's now a field commitInfoChoice, which is an enum with (currently) three possible values NONE, AUTHORS, or AUTHORS_AND_TITLES.
I've also looked at the new generic DSL version, but going from
mattermost {
	endpoint(MATTERMOST_HOOK_URL)
	notifyFailure()
}
to
mattermostNotifier {
	endpoint(MATTERMOST_HOOK_URL)
	room(null)
	icon(null)
	buildServerUrl(null)
	sendAs(null)
	startNotification(false)
	notifyAborted(false)
	notifyFailure(true)
	notifyNotBuilt(false)
	notifySuccess(false)
	notifyUnstable(false)
	notifyBackToNormal(false)
	notifyRepeatedFailure(false)
	includeTestSummary(false)
	commitInfoChoice('NONE')
	includeCustomMessage(false)
	customMessage(null)
}
is not exactly an attractive proposition (undocumented, no IDE support, can't leave out default valued fields, very little advantage over a configure block).
