Hit this as well on 2.176.3. Downgraded to 1.20 (the downgrade version offered on the Plugins page) and things work again.

Re: NPE when trying to use claim plugin after upgrading to jenkins 2.191

It seems to be a kind of compatibility-missmatch between claim- and bfa-plugin.

The claim plugin checks uses following code (see ClaimBuildFailureAnalyzer.java #44):

public static boolean isBFAEnabled() {
return (Jenkins.getInstance().getPlugin("build-failure-analyzer") != null
&& Jenkins.getInstance().getPlugin(PluginImpl.class).isGlobalEnabled());
{{ }}}

With release 1.23.0 of the plugin Build Failure Analyzer the class PluginImpl does no longer extends the interface hudson.Plugin, it was changed to jenkins.model.GlobalConfiguration.
I guess, that the core-method getPlugin returns null and therefore, another GlobalConfiguration-compatible implementation has to be used (for this newer bfa-release).
