looks to me https://github.com/jenkinsci/release-plugin/commit/54a13e3f7af9035eb091a0f6880ccf677523899c the last commit breaks it

Yup, that's my change. It works fine on my 1.574 version of Jenkins but not the latest 1.608.

Error from log is:

WARNING: Caught exception evaluating: h.filterDescriptors(it,attrs.descriptors) in /job/test/configure. Reason: java.lang.NullPointerException
java.lang.NullPointerException
	at hudson.model.DescriptorVisibilityFilter.apply(DescriptorVisibilityFilter.java:53)
	at hudson.Functions.filterDescriptors(Functions.java:1726)
	at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)

I'll try to find out why and fix it.

Edit:
Ok, the reason it's failing is because in config.jelly I changed the h.xxxx methods to instance.xxxx calls. These fail because a newly added instance will always be null. I guess it must have worked for me because I already had the previous release plugin installed at some point, and to my shame I didn't test it on a completely new install.

The reason it was changed to 'instance' was so that it could call the function getBuildSteps() that returns both publishers and builder descriptors in one list so they can both be used as build steps.

Thanks, looking forward to your fix.

Here is a fix for the issue and I also added a unit test to check for the presence of the "Release" links in the job page when the release check-box is enabled.

Thanks Glen

tested the latest jenkins-release-plugin from source and the 'release' does not show up at navigation bar. It works when I revert it. The log does not show any error

@dan tran, Was that from my fork or the official git repo? I haven't done a pull request yet to the official so it hasn't been merged.

I'm having difficulty reproducing this issue, can you post more information about the environment you are using to test and maybe some steps to reproduce (including any and all versions that you are using) as well?

In addition can you verify the "Configure release build" option is enabled in the job configuration?

@Glen

Yes It is from your fork. I am using Jenkins 1.596.2, suse 11.3 x64, jdk8. I can see the release configuration in my job, and when enable, configured and save the job config, the release option at navigation is not visible

Not sure what more I can provide
