Violation Comments to GitLab Plugin

This is a Jenkins plugin for Violation Comments to GitLab Lib. This plugin will find report files from static code analysis and comment GitLab pull requests with the content.

An alternative is also to have violations-command-line convert the violations to CodeClimate format and upload that to GitLab. It is explained in readme of violations-command-line.

Available in Jenkins here.

Example of supported reports are available here.

There is a complete running example available here: https://github.com/tomasbjerre/jenkins-configuration-as-code-sandbox

You can also do this with a command line tool.

A number of parsers have been implemented. Some parsers can parse output from several reporters.

52 parsers and 79 reporters.

Missing a format? Open an issue here!

There is also:

• violation-comments-to-gitlab-command-line.
• violations-command-line, can transform reports to CodeClimate.

Notify Jenkins from GitLab

• You may trigger with a webhook in GitLab. And consume it with Generic Webhook Trigger plugin to get the variables you need.

• Or, trigger with GitLab plugin.

• Or, trigger with GitLab Merge Request Builder Plugin.

Merge

You must perform the merge before build. If you don't perform the merge, the reported violations will refer to other lines then those in the pull request. The merge can be done with a shell script like this.

echo ---
echo --- Merging from $FROM in $FROMREPO to $TO in $TOREPO
echo ---
git clone $TOREPO
cd *
git reset --hard $TO
git status
git remote add from $FROMREPO
git fetch from
git merge $FROM
git --no-pager log --max-count=10 --graph --abbrev-commit

Your build command here!

Screenshots

Comments can be made on the diff with one comment per violation createSingleFileComments.

Or one big comment can be made, createCommentWithAllSingleFileComments.

Job DSL Plugin

This plugin can be used with the Job DSL Plugin. Here is an example using Generic Webhook Trigger plugin, HTTP Request Plugin and Conditional BuildStep Plugin.

Pipeline Plugin

Here is an example pipeline that will merge, run unit tests, run static code analysis and finally report back to GitLab. It requires the GitLab Plugin.

pipelineJob("merge-request-pipeline") {
 concurrentBuild()
 quietPeriod(0)
 authenticationToken("thetoken")
 triggers {
  genericTrigger {
   genericVariables {
    genericVariable {
     key("MERGE_REQUEST_TO_URL")
     value("\$.object_attributes.target.git_http_url")
     expressionType("JSONPath")
     regexpFilter("")
    }
    genericVariable {
     key("MERGE_REQUEST_FROM_URL")
     value("\$.object_attributes.source.git_http_url")
     expressionType("JSONPath")
     regexpFilter("")
    }
    genericVariable {
     key("MERGE_REQUEST_TO_BRANCH")
     value("\$.object_attributes.target_branch")
     expressionType("JSONPath")
     regexpFilter("")
    }
    genericVariable {
     key("MERGE_REQUEST_FROM_BRANCH")
     value("\$.object_attributes.source_branch")
     expressionType("JSONPath")
     regexpFilter("")
    }
    genericVariable {
     key("PROJECT_ID")
     value("\$.object_attributes.target_project_id")
     expressionType("JSONPath")
     regexpFilter("")
    }
    genericVariable {
     key("PROJECT_PATH")
     value("\$.object_attributes.target.path_with_namespace")
     expressionType("JSONPath")
     regexpFilter("")
    }
    genericVariable {
     key("MERGE_REQUST_IID")
     value("\$.object_attributes.iid")
     expressionType("JSONPath")
     regexpFilter("")
    }
    genericVariable {
     key("MR_OBJECT_KIND")
     value("\$.object_kind")
     expressionType("JSONPath")
     regexpFilter("")
    }
    genericVariable {
     key("MR_OLD_REV")
     value("\$.object_attributes.oldrev")
     expressionType("JSONPath")
     regexpFilter("")
    }
    genericVariable {
     key("MR_ACTION")
     value("\$.object_attributes.action")
     expressionType("JSONPath")
     regexpFilter("")
    }
    genericVariable {
     key("MR_TITLE")
     value("\$.object_attributes.title")
     expressionType("JSONPath")
     regexpFilter("")
    }
   }
   regexpFilterText("\$MR_OBJECT_KIND \$MR_ACTION \$MR_OLD_REV")
   regexpFilterExpression("^merge_request\\s(update\\s.{40}\$|open.*)")
  }
 }
 
 definition {
  cps {
   script(readFileFromWorkspace('merge_request_pipeline.pipeline'))
   sandbox()
  }
 }
}

And the merge_request_pipeline.pipeline contains

def commentMr(projectId, mergeRequestIid, comment) {
 def body = comment
 .replaceAll(" ","%20")
 .replaceAll("/","%2F")
 def project = projectId
 .replaceAll("/","%2F")
 sh "curl http://gitlab:80/api/v4/projects/$project/merge_requests/$mergeRequestIid/notes -H 'PRIVATE-TOKEN: 6xRcmSzPzzEXeS2qqr7R' -X POST -d \"body="+body+"\""

}

Encoding

The commentTemplate parameter can be used to fix encoding problems, or just adjust what is being commented. See README in violation-comments-lib.

Plugin development

More details on Jenkins plugin development is available here.

There is a /build.sh that will perform a full build and test the plugin.

If you have release-permissions this is how you do a release:

mvn release:prepare release:perform
