Experiencing a bug with the latest release of the Git-Pugin (3.9.0).

The following stage within a Declarative Pipeline yields a Java enum constant failure in relation to the git-client plugin.

         stage("Clone source, execute local merge"){
            steps{
                dir("source"){
                    script{
                        // Pull the source and test a merge
                        def sourceScmCheck = checkout changelog: true, poll: true, scm: [
                          $class: 'GitSCM',
                          branches: [[name: "origin/sourceBranch"]],
                          doGenerateSubmoduleConfigurations: false,
                          extensions: [[
                            $class: 'PreBuildMerge',
                            options: [
                              fastForwardMode: 'FF',
                              mergeRemote: 'origin',
                              mergeStrategy: 'default',
                              mergeTarget: "targetBranch"
                            ]
                          ]],
                          submoduleCfg: [],
                          userRemoteConfigs: [[
                            credentialsId: 'gitcredentialshere',
                            name: 'origin',
                            url: "https://somegit.somewhere"
                          ]]
                        ]
                    }
                }
            }
        }

This yields the following error:

Downgrading the git-plugin to version 3.8.0 resolves the issue. No changes to the git-client plugin were needed.

Is the problem resolved if you change the value of the mergeStrategy from 'default' to 'DEFAULT'?

markewaite - Yes, it is. Looks like the case insensitivity got lost somewhere. Is that something that can get added back in, or should we move to uppercase?

Move to upper case is something you can do immediately, rather than waiting for a new release of the plugin. I'll need to add regression tests of pipeline based pre-build merge. Once I've added those regression tests (in my jenkins-bugs repository), then I would investigate the necessary code change to fix the regression tests.

I think making those code changes would be beneficial. The majority of resources online that depict how to do pre-build merges use lowercase in their examples (See the GitLab plugin GitHub page as an example). I expect quite a few people will run into this issue once they upgrade the plugin.

I had this issue after the upgrade, however, the mergeStrategy was already DEFAULT, so I suspect there is something else going on here. Only downgrading resolved the issue.

+1 on this issue.

Had to switch to upper case to workaround this issue.

I'm also seeing this, and I'm already using uppercase and still not help.

Changing

mergeStrategy: 'MergeCommand.Strategy.DEFAULT'

mergeStrategy: 'DEFAULT',

May also be necessary.

Gao Ningning added a comment - 2019-02-20 08:28

Also met the same issue, change the value of the mergeStrategy from 'default' to 'DEFAULT' can solve problem.

It is interesting that 'default' can work in lower Git Plugin version, but exception happened in high verison.

Jesse Glick added a comment - 2019-04-02 01:26

mergeStrategy: 'DEFAULT' (or similarly uppercase for the other options) is correct, or simply omit this parameter since DEFAULT is, well, the default. It is hard to say what would have been legal in older plugin versions (actually honored values) since it performed no validation on this parameter and (as in ~~JENKINS-34070~~) the snippet generator was broken. I do not see a good way to make this plugin tolerate the lowercase syntax; there is not a general API in DescribableModel permitting arbitrary customizations to the introspected structure. (At top level, a StepDescriptor can override newInstance and uninstantiate, but this does not apply to structures used as nested arguments.)

Jesse Glick added a comment - 2019-04-02 01:26 mergeStrategy: 'DEFAULT' (or similarly uppercase for the other options) is correct, or simply omit this parameter since DEFAULT is, well, the default. It is hard to say what would have been legal in older plugin versions (actually honored values) since it performed no validation on this parameter and (as in JENKINS-34070 ) the snippet generator was broken. I do not see a good way to make this plugin tolerate the lowercase syntax; there is not a general API in DescribableModel permitting arbitrary customizations to the introspected structure. (At top level, a StepDescriptor can override newInstance and uninstantiate , but this does not apply to structures used as nested arguments.)

A proper fix would require something like ~~JENKINS-44892~~, which has been discussed for some time but never prototyped.

Fix merged in the 4.x trunk, and a 3.10.x backport is in preparation.

The fix that jglick has provided is working well in my testing of git plugin 4.0 pre-release. I can see the failure with git plugin 3.9.4 and can confirm that it is resolved in the 4.0 pre-release. I haven't yet tested it with the git plugin 3.10 pre-release, but I expect no issue in that pre-release version either.

While testing the fix that jglick has provided for git plugin 4.0 and git plugin 3.10, I found a null pointer exception that I need to investigate further when using JGit as the git implementation. The stack trace was:

java.lang.NullPointerException

I'll refer to my jenkins-bugs test repository for the details.
