            Helping understand functions in Jenkins Groovy pipeline
            Asked 2021-Jun-15 at 00:27

            I'm trying to understand the syntax and methods of the following groovy script used in a jenkins pipeline:



            Answered 2021-Jun-15 at 00:27

            This is a map that contains maps. [:] is the literal syntax for an empty map. Otherwise the map would be null and you couldn’t add anything to it. The map gets populated with 2 more maps. The argument you pass in decides which of the 2 maps is returned, if the argument doesn’t match either content1 or content2 the function returns null.

            If you have groovy installed on your computer you can try your posted code out in groovyConsole and see what it does.

            your POST code is fine.

            problem not in content size , but in a way you are building json payload.

            you have doublequotes in content

            Update: Issue #17383 has been fixed and is targeted for Gradle 7.2.

            You may hit a bug in Gradle. I was able to reproduce the issue by forcing tr-TR locale in environment variable JAVA_TOOL_OPTIONS. I filed a bug in the Gradle issue tracker to have this checked: Build init plugin is locale sensitive.

            As a workaround, you could force English locale for project initialization, in Powershell:

            Apache Groovy provides extension methods to aid with creating temporary directories. Prior to this fix, Groovy's implementation of those extension methods was using a now superseded Java JDK method call that is potentially not secure on some operating systems in some contexts. Users not using the extension methods mentioned in the advisory are not affected, but may wish to read the advisory for further details. Versions Affected: 2.0 to 2.4.20, 2.5.0 to 2.5.13, 3.0.0 to 3.0.6, and 4.0.0-alpha-1. Fixed in versions 2.4.21, 2.5.14, 3.0.7, 4.0.0-alpha-2.
            A sandbox bypass vulnerability exists in Jenkins Groovy Plugin 2.1 and earlier in pom.xml, src/main/java/hudson/plugins/groovy/ that allows attackers with Overall/Read permission to execute arbitrary code on the Jenkins master JVM.

            Install groovy

            You can download it from GitHub, Maven.
            You can use groovy like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the groovy component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer For Gradle installation, please refer .
