### Update GitHub Commit Status with Multiple SCM Sources

Source: https://github.com/jenkinsci/github-plugin/blob/master/README.md

A more complex example for updating GitHub commit status, suitable for pipelines with multiple SCM sources. It includes workarounds for known issues and handles various build result states.

```groovy
def getRepoURL() {
  sh "git config --get remote.origin.url > .git/remote-url"
  return readFile(".git/remote-url").trim()
}

def getCommitSha() {
  sh "git rev-parse HEAD > .git/current-commit"
  return readFile(".git/current-commit").trim()
}

def updateGithubCommitStatus(build) {
  // workaround https://issues.jenkins-ci.org/browse/JENKINS-38674
  repoUrl = getRepoURL()
  commitSha = getCommitSha()

  step([
    $class: 'GitHubCommitStatusSetter',
    reposSource: [$class: "ManuallyEnteredRepositorySource", url: repoUrl],
    commitShaSource: [$class: "ManuallyEnteredShaSource", sha: commitSha],
    errorHandlers: [[$class: 'ShallowAnyErrorHandler']],
    statusResultSource: [
      $class: 'ConditionalStatusResultSource',
      results: [
        [$class: 'BetterThanOrEqualBuildResult', result: 'SUCCESS', state: 'SUCCESS', message: build.description],
        [$class: 'BetterThanOrEqualBuildResult', result: 'FAILURE', state: 'FAILURE', message: build.description],
        [$class: 'AnyBuildResult', state: 'FAILURE', message: 'Loophole']
      ]
    ]
  ])
}
```

```

--------------------------------

### Upload Jenkins Plugin to java.net with Maven

Source: https://github.com/jenkinsci/github-plugin/blob/master/README.md

The `hpi:upload` goal is used during the release process to post the built `.hpi` file to java.net.

```bash
hpi:upload
```

--------------------------------

### Prepare and Perform Plugin Release with Maven

Source: https://github.com/jenkinsci/github-plugin/blob/master/README.md

Utilize the Maven release plugin to prepare and perform a release of your Jenkins plugin. Ensure you provide valid username and password credentials.

```bash
mvn release:prepare release:perform -Dusername=juretta -Dpassword=******
```

--------------------------------

### Generate Jenkins Plugin .hpl File with Maven

Source: https://github.com/jenkinsci/github-plugin/blob/master/README.md

The `hpi:hpl` goal generates a `.hpl` file, which is a descriptor file for the plugin.

```bash
hpi:hpl
```

--------------------------------

### Javadoc for Class Members

Source: https://github.com/jenkinsci/github-plugin/blob/master/CONTRIBUTING.md

Standard Javadoc format for getters and setters. Ensure all public and protected methods have Javadoc comments.

```java
/**
 * The count of widgets
 */
private int widgetCount;

/**
 * Returns the count of widgets.
 *
 * @return the count of widgets.
 */
public int getWidgetCount() {
    return widgetCount;
}

/**
 * Sets the count of widgets.
 *
 * @param widgetCount the count of widgets.
 */
public void setWidgetCount(int widgetCount) {
    this.widgetCount = widgetCount;
}
```

--------------------------------

### Set Commit Status in Jenkins Pipeline

Source: https://github.com/jenkinsci/github-plugin/blob/master/README.md

Use this function to set the commit status for a custom repository with a configured context and message. Ensure the GitHub plugin is configured correctly.

```groovy
void setBuildStatus(String message, String state) {
  step([
      $class: "GitHubCommitStatusSetter",
      reposSource: [$class: "ManuallyEnteredRepositorySource", url: "https://github.com/my-org/my-repo"],
      contextSource: [$class: "ManuallyEnteredCommitContextSource", context: "ci/jenkins/build-status"],
      errorHandlers: [[$class: "ChangingBuildStatusErrorHandler", result: "UNSTABLE"]],
      statusResultSource: [ $class: "ConditionalStatusResultSource", results: [[$class: "AnyBuildResult", message: message, state: state]] ]
  ]);
}

setBuildStatus("Build complete", "SUCCESS");
```
