GitStep is missing its descriptor with example build

I've been testing the waters of Jenkins 2 as I'm interested in the pipeline workthrough but hit a snag.

1.

 
                                                    docker run -p 8080:8080 -p 50000:50000 --name jenkins2 jenkinsci/jenkins:2.8 
                                                

2. Log in, create account, etc
3. Create Pipeline project
4. Configure
5. In Pipeline section, "try sample pipeline" > "Github + Maven"

Behaviour:

 
                                                    java.lang.AssertionError: class org.jenkinsci.plugins.workflow.steps.scm.GitStep is missing its descriptor
	at jenkins.model.Jenkins.getDescriptorOrDie(Jenkins.java:1304)

I get the same error when attempting to point to my own github repo.

I also have the exact same issue with the 2.8 docker image.

Re: GitStep is missing its descriptor with example build

Do you have Git installed?

The sample pipeline docs include the step:

> 2. Only if you do not have Git installed on your Jenkins server: click Delete Git on the default Git installation and Add Git » JGit to replace it.

I had this exact error message. In my case, I had installed Git on the Jenkins server, but failed to restart Jenkins. After restarting Jenkins it was fixed.
