Plugin Library Provider
JTE makes it possible to package a set of libraries into a Jenkins Plugin.
When a library-providing plugin has been installed, a new option becomes available when selecting a library source:
From a Library Providing Plugin, just select the library providing plugin from the autopopulated dropdown list.
It’s a lot less work to configure a source code repository and configure it as a library source. So why would someone want to spend the time packaging their libraries as a Jenkins Plugin?
Steps contributed by libraries often rely on Jenkins plugins in their implementation. Packing libraries as a Jenkins Plugin ensures that all other plugin dependencies (and their versions) are satisfied when the library providing plugin is installed.
It slows down library loading to reach out to a remote source code repository to retrieve libraries. When libraries are packaged in a Jenkins Plugin, library loading can be sped up significantly.
It can be helpful to ensure that specific version of the Templating Engine Plugin is installed if the interface between JTE and libraries is changed.
One specific use-case for the Templating Engine Plugin is for DevOps engineers supporting multiple pipelines simultaneously. In these situations, the libraries provided are likely shared across the teams as well. Over time, libraries can be changed in a way that breaks backwards compatibility. Packaging libraries as a plugin allows you to version your set of libraries as an artifact where teams can upgrade when it makes the most operational sense.
We have created a sample repository you can use as a launching pad for packaging your libraries as a plugin.
Checkout the jte-libs-as-a-plugin repository to get started.
If packaging your libraries via a Jenkins Plugin, we recommend configuring your library source as a SCM Library during development.
If you’re following the repository template based off of the sample repository mentioned above, you would configure the SCM Library repository URL and set the base directory to
This way, you can continuously push updates to the remote repository for testing, and only once you’re satisfied with the changes, increment the version and package the libraries as a plugin.
