Few more notes: caller.groovy and firstPipe.groovy are in the same git repo, and if I eliminate usage of the global library, everything works fine. I'm using declarative pipeline and would like to continue to do so.
The version could be anything understood by that SCM; for example, branches,tags, and commit hashes all work for Git. You may also declare whether scriptsneed to explicitly request that library (detailed below), or if it is presentby default. Furthermore, if you specify a version in Jenkins configuration,you can block scripts from selecting a different version.

If your SCM plugin has not been integrated, you may select Legacy SCM andpick anything offered. In this case, you need to include$library.yourLibName.version somewhere in the configuration of the SCM, sothat during checkout the plugin will expand this variable to select the desiredversion. For example, for Subversion, you can set the Repository URL tosvnserver/project/$library.yourLibName.version and then useversions such as trunk or branches/dev or tags/1.0.
Other plugins may add ways of defining libraries on the fly. For example, thePipeline: GitHub Groovy Libraries pluginallows a script to use an untrusted librarynamed like github.com/someorg/somerepo without any additional configuration. Inthis case, the specified GitHub repository would be loaded, from the masterbranch, using an anonymous checkout.
For Shared Libraries which only define Global Variables (vars/), or aJenkinsfile which only needs a Global Variable, theannotationpattern Library('my-shared-library') _ may be useful for keeping codeconcise. In essence, instead of annotating an unnecessary import statement,the symbol _ is annotated.
As of version 2.7 of the Pipeline: Shared Groovy Libraries plugin,there is a new option for loading (non-implicit) libraries in a script:a library step that loads a library dynamically, at any time during the build.
However you may use library classes dynamically (without type checking),accessing them by fully-qualified name from the return value of the library step.static methods can be invoked using a Java-like syntax:
The "Default version" for a configured Shared Library is used when "Loadimplicitly" is checked, or if a Pipeline references the library only by name,for example Library('my-shared-library') _. If a "Default version" is notdefined, the Pipeline must specify a version, for example Library('my-shared-library master') _.
Note that the library step may not be used to override the version of an implicitly loaded library.It is already loaded by the time the script starts, and a library of a given name may not be loaded twice.
If you only specify a library name (optionally with version after ) in the library step,Jenkins will look for a preconfigured library of that name.(Or in the case of a github.com/owner/repo automatic library it will load that.)
For example, to define sayHello, the file vars/sayHello.groovyshould be created and should implement a call method. The call methodallows the global variable to be invoked in a manner similar to a step:
It is possible to use third-party Java libraries, typically found inMaven Central,from trusted library code using the Grab annotation. Refer to theGrape documentationfor details, but simply put:
(Even if the version requested for the library was a branch, rather than a fixed version like a tag,replayed builds will use the exact same revision as the original build:library sources will not be checked out again.)
Only entire pipelines can be defined in shared libraries as of this time.This can only be done in vars/*.groovy, and only in a call method. Only oneDeclarative Pipeline can be executed in a single build, and if you attempt toexecute a second one, your build will fail as a result.
By adding Library('my-shared-library pull//head') _ at the top of a library consumer Jenkinsfile, you can test your pipeline library pull request changes in situ if your pipeline library is hosted on GitHub and the SCM configuration for the pipeline library uses GitHub.
Refer to the pull request or merge request branch naming convention for other providers like Assembla, Bitbucket, Gitea, GitLab, and Tuleap.
This guide demonstrates how to create a Groovy library with Gradle using gradle init.You can follow the guide step-by-step to create a new project from scratch or download the complete sample project using the links above.
From inside the new project directory, run the init task using the following command in a terminal: gradle init.When prompted, select the 3: library project type and 2: Groovy as implementation language.Next you can choose the DSL for writing buildscripts - 1 : Groovy or 2: Kotlin.For the other questions, press enter to use the default values.
Each shared library requires users to define a name and a method of retrieving source code. These methods include local files, Git repositories, and Jenkins SCM plugins. Optionally, users can also set a default library version.
Another method is to link directly to a Git repository containing a library. When configuring a pipeline, scroll down to the Pipeline section and select the Pipeline script from SCM option from the Definition drop-down menu.
Groovy library - specify the Groovy SDK. IntelliJ IDEA expects the standard Groovy SDK layout which is provided with the official distributions available at -lang.org/download.html. Download the SDK, unpack it into any directory and specify this directory as the library home.
In my company I inherit a company-wide shared Jenkins library that is 80% script-based (i.e. most .groovy files are scripts under /vars, not groovy classes under src/groovy). I wrote a new Library for my project, extending the company-wide one and in my project's declarative pipelines I use both.
I have placed this class definition in a shared library git repo, with the path apiCode/src/apicode/apiCode.groovy. I am importing the shared library using the following step at the top of my Jenkins file, outside any node or pipeline directive:
I actually tested the same by adding the global library path under Jenkins configuration and used the below simple code to load the class into my Jenkins and it worked perfectly fine. and the issue is coming only when I am loading it dynamically.
I have used the below plugin, which will give me an option to implicitly configure the libraries for individual multibranch pipelines. after configuring it I can simply import the class from the shared library with the import command.
Remember that the script files must be valid classes, not just arbitrary scripts. So as an example, lets setup one of these Groovy objects. First, create a directory (e.g. C:\GroovyLib). Then add a Callee.groovy file in that directory with the following content:
Hello Robin. Since your last comment is 4 years old, I was wondering, if there might be another solution to this "shared groovy" problem in the newest QB versions.
So far, we've been using your suggestion (custom plugin with utility classes) to share common functions in groovy scripts.
Hi all,I wan to use the point cloud in ros groovy for Ubuntu ARM, I think I will build manually from source code because it is still not supported,just only has source code. So Is there any one build successfully pcl, please give me some advices , what is the neccessay library which I must install first.Thanks in advance.
Typically, all five applications need their own Jenkinsfile, but the content of the Jenkinsfiles is going to be mostly the same. Jenkins Shared Library avoids this repetition of pipeline code by creating a shared library.
Create a file called welcomeJob.groovy inside the vars folder. (camel casing is mandatory for file names). The filename welcomeJob will be used later by Jenkinsfile to access this Jenkins pipeline library.
When a shared library is referred from the Jenkins job, Jenkins, by default, will invoke the call() function within our Groovy file. Consider the call() function like the main() method in Java. We can also specify parameters for the call() function if we want to.
Library will import the shared library to our Jenkins job. (Remember first-shared-lib is the name we gave while configuring shared libraries in Manage Jenkins. Refer to the previous section of this article).
I enjoy the power of groovy scripting FlowFiles using the ExecuteScript processor. Can I import external libraries to fully leverage the groovy framework in Nifi? If so, how do I implement a jar file in the ExecuteScript processor?
But how to include the jars which are already supported by the nifi ? Like the hadoop jars which i feel is more safer to use the ones packed with the nifi. we have a use case to access some configurations which is written in Hadoop configuration file pattern. We want to access it through nifi but seems like through groovy script i am not able to access it without giving external module dependencies. Any way to safely refer to the nifi jars ?
The 1st problem is that it is bothersome recording the duration using a stopwatch device. I introduced the Apache Commons StopWatch library into my test scripts to measure the duration and print the figure in console messages.
Below is a list of ready to use standard sample groovy scripts which can be used directly in groovy script based system tasks. Click on the groovy script name / purpose to go directly to the concerned groovy script.
Apache Groovy is a scripting language that has become the default option in JMeter JSR223 elements. To accommodate that, the Groovy library has been included by default in JMeter ever since version 3, and no manual steps need to be performed to use it. Previous JMeter versions required downloading Groovy and manually including it in JMeter libraries.
Enter org.codehaus.groovy:groovy-all:2.4.12 in the input field, and press OK. This will automatically download the library for Groovy version 2.4.12 (version of Groovy used in CPI at the time of writing) from the public Maven repository.
