Jenkins SCM-Manager 2 Plugin
This plugin gives various ways to connect your SCM-Manager with Jenkins, like sending build status, multibranch pipelines, folders for complete namespaces and navigation items.
Once the plugin is installed, it will automatically detect jobs which have configured scm that points to an instance of SCM-Manager v2. If such a build job starts, the plugin will send the PENDING state for the checkout revision to SCM-Manager. After the build is complete the plugin will send the resulting state to SCM-Manager (SUCCESS, UNSTABLE or FAILURE).
For multibranch pipelines there is a new branch source named "SCM-Manager", so you can create pipelines in Jenkins that can find branches, tags and pull requests in SCM-Manager hosted repositories on their own. In cooperation with the jenkins plugin in SCM-Manager the Jenkins ci server will receive hooks on every change and trigger new builds. To remove stale jobs like for no longer available repositories, you can manually execute "Scan Namespace Now".
To create such a pipeline, select "New Item" on the Jenkins top level page, then enter a name and select "Multibranch Pipeline".
In the configuration form for this item, select the matching "SCM-Manager" entry for your repository type in the "Add source" dropdown in the section "Branch Sources".
In the new configuration enter the base URL of your SCM-Manager instance and select according credentials. This plugin will then load a list of all available repositories you can select from.
Finally you can select behaviours where you can choose for example, whether branches, tags or pull requests shall be build.
In order to create a SCM-Manager Mercurial or Git repository with the Jenkins JobDSL the following syntax can be used:
multibranchPipelineJob('heart-of-gold') {
branchSources {
scmManager {
id('spaceships/heart-of-gold')
serverUrl('https://scm.hitchhiker.com')
credentialsId('my-secret-id')
repository('spaceships/heart-of-gold')
discoverBranches(true)
discoverPullRequest(true)
discoverTags(false)
}
}
}
The parameters discoverBranches, discoverPullRequest und discoverTags are optional and describe which heads of the repository are build. The example shows the default values.
For a Subversion repository have a look at the following example:
multibranchPipelineJob('heart-of-gold') {
branchSources {
scmManagerSvn {
id('spaceships/heart-of-gold')
serverUrl('https://scm.hitchhiker.com')
credentialsId('my-secret-id')
repository('spaceships/heart-of-gold')
includes("trunk,branches/*,tags/*,sandbox/*")
excludes("")
}
}
}
The parameters for includes und excludes are optional and describe which directories of the repository are build. The example shows the default values.
If you want to have build jobs for every repository in a namespace, you can create "SCM-Manager namespace" jobs. These will scan all repositories in the given namespace and create multibranch pipelines for each repository where a Jenkinsfile can be found. If a new repository is created in this namespace, a new pipeline will be created automatically.
To create such a folder for a complete namespace, select "New Item" on the Jenkins top level page, then enter a name and select "SCM-Manager Namespace".
In the configuration form for this item, enter the base URL of your SCM-Manager instance and select according credentials. This plugin will then load a list of all available namespaces you can select from.
As an alternative to a concrete namespace you can select --all-- if you want to create build jobs for all repositories of the whole SCM-Manager instance. Please note, that in this case the folders for the jobs will be named with the pattern namespace/name.
Finally you can select behaviours where you can choose for example, whether branches, tags or pull requests shall be build.
In order to create a build job for an SCM-Manager namespace with the job dsl, have a look at the following example:
organizationFolder("spaceships") {
organizations {
scmManagerNamespace {
serverUrl('https://scm.hitchhiker.com')
credentialsId('my-secret-id')
namespace("spaceships")
discoverBranches(true)
discoverPullRequest(true)
discoverTags(false)
discoverSvn {
includes("trunk,branches/*,tags/*,sandbox/*")
excludes("")
}
}
}
}
// scan namespace directly after creation
queue("spaceships")
The discover* parameters are optional, the example above shows the default values. To disable subversion builds, a false can be passed to the discoverSvn method e.g.: discoverSvn(false). To build all namespaces of the SCM-Manager instance, the pseudo namespace --all-- can be used.
In different pages of Jenkins you can find links to the corresponding SCM-Manager page:
- In multibranch pipelines you can find the link "SCM-Manager" in the main navigation on the left. This leads you directly to the main page of the repository in SCM-Manager.
- In a job for a concrete branch or a tag the link "SCM-Manager" in the main navigation on the left will get you directly to the sources in SCM-Manager for this branch or tag.
- In a job for a pull request the link "SCM-Manager" in the main navigation on the left will navigate to the pull request in SCM-Manager.
- From the page for a build result the link "SCM-Manager" in the main navigation on the left leads to the sources view in SCM-Manager for the concrete revision that has been build.
- In the "Changes" view there are links that lead to the details of a change showing the authors, the commit message and the diff for the commit.
For full functionality, this plugin requires SCM-Manager v2 with an installed jenkins plugin for the triggers and the CI plugin to show the build results inside SCM-Manager. To create ssh connection between Jenkins and SCM-Manager you can use the SSH plugin.
To build the plugin just run the maven package phase.
mvn package
Start the local Jenkins instance:
mvn hpi:run
