Groovy Postbuild

This plugin executes a groovy script in the Jenkins JVM. Typically, the script checks some conditions and changes accordingly the build result, puts badges next to the build in the build history and/or displays information on the build summary page.

Migration from 1.X

From version 2.0, Groovy Postbuild plugin introduces Script Security Plugin.
Administrators can prevent users without proper privileges from running harmful scripts.
For details, see Script Security Plugin.
This doesn't affect Jenkins without security enabled and users with administrative privilege (to be exact, with RUN_SCRIPTS permission).

When you upgrade the Groovy Postbuild plugin from 1.X to 2.X, you and your Jenkins users
also requires update configurations of Groovy Postbuild, or they will fail with outputs like this:

ERROR: Failed to evaluate groovy script.

Scripts using only whitelisted methods of manager

Scripts using only whitelisted methods of manager can run with using Groovy sandbox.
They can be validated only by checking "Use Groovy Sandbox".

Scripts using non-whitelisted methods

Scripts using non-whitelisted methods of manager or methods not of manager requires
approval of administrators.

Administrators should check and approve those scripts in Manage Jenkins > In-process Script Approval.

Scripts using external jar files

If you refer external jar files from your scripts, you need to have those jar files approved by administartors.

Administrators should check and approve those jar files in Manage Jenkins > In-process Script Approval.

Scripts using external class directories

Script Security Plugin doesn't support class directories.

If you refer external class directories from your scripts, you should archive them into jar files.
It can be performed by running a following command:

jar -cf mylib.jar -C /path/to/classes .

You can use /path/to/mylib.jar as an additonal classpath for scripts.

Usage

The groovy script can use the variable manager, which provides various methods to decorate your builds.
Those methods can be classified into whitelisted methods and non-whitelisted methods.
You can always use Whitelisted methods, but you can use Non-whitelisted methods only when "Enable groovy postbuild security" is not enabled (version 1.X) or in scripts approved by administrators (since version 2.x)

Whitelisted methods

  • getEnvVariable(key) - get a variable value. (since 1.10)
  • getResult() - get a build result string (like SUCCESS, FAILURE) (since 2.2)

 

  • logContains(regexp) - returns true if the build log file contains a line matching regexp.
  • getLogMatcher(regexp) - returns a java.util.regex.Matcher for the first occurrence of regexp in the build log file.

 

  • addShortText(text) - puts a badge with a short text, using the default format.

  • addShortText(text, color, background, border, borderColor) - puts a badge with a short text, using the specified format.  For Colors supported, Google "html color names".

  • addBadge(icon, text) - puts a badge with the given icon and text. In addition to the 16x16 icons offered by Jenkins, groovy-postbuild provides the following icons (watch out for duplicates, see Example 5):

    - completed.gif
    - db_in.gif
    - db_out.gif
    - delete.gif
    - error.gif
    - folder.gif
    - green.gif
    - info.gif
    - red.gif
    - save.gif
    - success.gif
    - text.gif
    - warning.gif
    - yellow.gif

 

  • addBadge(icon, text, link) - like addBadge(icon, text), but the Badge icon then actually links to the given link (since 1.8)
  • addInfoBadge(text) - puts a badge with info icon and the given text.
  • addWarningBadge(text) - puts a badge with warning icon and the given text.
  • addErrorBadge(text) - puts a badge with error icon and the given text.
  • addHtmlBadge(html) - puts a badge with html source (since 2.5). Unsafe html codes will be removed.
  • removeBadges() - removes all badges from the current build. It is often used with setBuildNumber.
  • removeBadge(index) - removes the badge with the given index. It is often used with setBuildNumber.

 

  • buildUnstable() - sets the build result to UNSTABLE.
  • buildFailure() - sets the build result to FAILURE.
  • buildSuccess() - sets the build result to SUCCESS.

 

  • buildIsA(klass) - test the build is a specified class (since 2.0)

Non-whitelisted methods

Methods returning non-primitive objects aren't whitelisted as groovy-postbuild doesn't ensure every methods of those objects are safe.

 

  • envVars - the build variables map. You can get a variable value with

    manager.envVars['varname']

    You shouldn't update values. This isn't whitelisted, and it is recommended to use getEnvVariable(key) instead. (since 1.10)

 

  • contains(file, regexp) - returns true if the given file contains a line matching regexp. Not whitelisted as it allows users access any files (for example, a file containing passwords).
  • getMatcher(file, regexp) - returns a java.util.regex.Matcher for the first occurrence of regexp in the given file.

 

  • setBuildNumber(number) - sets the build with the given number as current build. The current build is the target of all methods that add or remove badges and summaries or change the build result.

 

  • createSummary(icon) - creates an entry in the build summary page and returns a summary object corresponding to this entry. The icon must be one of the 48x48 icons offered by Jenkins. You can append text to the summary object by calling its appendText methods. Be careful appending HTML-unescaped texts as they can be harmful.
    • appendText(text, escapeHtml)
    • appendText(text, escapeHtml, bold, italic, color)
  • removeSummaries() - removes all summaries from the current build.
  • removeSummary(index) - removes the summary with the given index.

Rest interfaces

It is also possible to delete badges and summaries by using the following links:

  • remove all badges:
    • http``://``your-jenkins``/job/``your-job``/``build-number``/parent/parent/plugin/groovy-postbuild/removeBadges

 

  • remove all summaries:
    • http``://``your-jenkins``/job/``your-job``/``build-number``/parent/parent/plugin/groovy-postbuild/removeSummaries

 

  • remove the badge with the given index:
    • http``://``your-jenkins``/job/``your-job``/``build-number``/parent/parent/plugin/groovy-postbuild/removeBadge?index=``idx

 

  • remove the summary with the given index:
    • http``://``your-jenkins``/job/``your-job``/``build-number``/parent/parent/plugin/groovy-postbuild/removeSummary?index=``idx

Example usages

Example 1

The script below puts a warning badge and mark the build as unstable if it detects that deprecated methods were used.

if(manager.logContains(".*uses or overrides a deprecated API.*")) {
    manager.addWarningBadge("Thou shalt not use deprecated methods.")
    manager.createSummary("warning.gif").appendText("<h1>You have been warned!</h1>", false, false, false, "red")
    manager.buildUnstable()
}

[TABLE]

Example 2

Suppose we have a parameterized build, which uses the boolean parameter storeToDB in order to instruct the build to store some artifacts into the database. The script below puts a badge next to the builds for which this parameter is set.

if("true".equals(manager.build.buildVariables.get("storeToDB"))) {
    manager.addBadge("db_in.gif", "Stored to DB")
}

Example 3

Suppose we have a parameterized build, which uses the string parameter version. The script below puts a short text indicating the value of this parameter next to successful and unstable builds.

if(manager.build.result.isBetterOrEqualTo(hudson.model.Result.UNSTABLE)) {
    manager.addShortText("v${manager.build.buildVariables.get('version')}")
}

Example 4

The script below determines how long it took to build the project and displays the corresponding value as a short text next to each build.

def matcher = manager.getLogMatcher(".*Total time: (.*)\$")
if(matcher?.matches()) {
    manager.addShortText(matcher.group(1), "grey", "white", "0px", "white")
}

Example 5

For badges, you can choose from the 16x16 icons provided by Jenkins or from the icons provided by this plugin. Some of the names of groovy-postbuild icons conflict with the names of Jenkins icons (e.g. yellow.gif). For these icons, you have to provide the complete path (e.g. /images/16x16/yellow.gif), in case you want a badge with the Jenkins icon. You can also use icons provided by other plugins (e.g. Green Balls), by specifying the complete path to the icon.

manager.addBadge("star-gold.gif", "icon from Jenkins")
manager.addBadge("yellow.gif", "icon from groovy-postbuild plugin")
manager.addBadge("/images/16x16/yellow.gif", "icon from Jenkins")
manager.addBadge("/plugin/greenballs/16x16/green.gif", "icon from greenballs plugin")

Example 6

The script below displays on the build summary page all classes that use Sun proprietary API.

pattern = ~/.*src\/main\/java\/(.*)\.java:[^ ]* (.*) is Sun proprietary API and may be removed in a future release.*/
def map = [:]
manager.build.logFile.eachLine { line ->
    matcher = pattern.matcher(line)
    if(matcher.matches()) {
        ownClass = matcher.group(1).replaceAll("/", ".")
        sunClass = matcher.group(2)
        map[ownClass] = sunClass
    }
}
if(map.size() > 0) {
    def summary = manager.createSummary("warning.gif")
    summary.appendText("Classes using Sun proprietary API:<ul>", false)
    map.each {
        summary.appendText("<li><b>$it.key</b> - uses $it.value</li>", false)
    }
    summary.appendText("</ul>", false)
}

Example 7

The script below removes all badges and summaries from previous builds.

currentBuildNumber = manager.build.number
for(i=1; i<currentBuildNumber; i++) {
    if(manager.setBuildNumber(i)) {
        manager.removeBadges()
        manager.removeSummaries()
    }
}

Example 8

The script below marks the running build as deployed and the previous build as undeployed.

manager.addShortText("deployed")
manager.createSummary("gear2.gif").appendText("<h2>Successfully deployed</h2>", false)

currentBuildNumber = manager.build.number
if(manager.setBuildNumber(currentBuildNumber - 1)) {
   actions = manager.build.actions
    actions.each { action ->
        if (action.metaClass.hasProperty(action, "text") && action.text.contains("deployed")) {
            actions.remove(action)
        }
    }
    currDate = new Date().dateTimeString
    manager.addShortText("undeployed: $currDate", "grey", "white", "0px", "white")
    manager.createSummary("gear2.gif").appendText("<h2>Undeployed: $currDate</h2>", false, false, false, "grey")
}

Example 9 (thanks to Ken Bertelson)

The script below changes the description of the first failed test.

def tr = manager.build.testResultAction.result
def cr = tr.failedTests.get(0)
cr.description = "My CaseResult desc"

Example 10 (thanks to Frank Merrow)

Trivial, but hard to find the first time: Write a line to the job's Console Output:

manager.listener.logger.println("I want to see this line in my job's output");
