Installing Groovy Script Engine

1 Summary
2 Install into Jira/lib
- 2.1 Java 8
- 2.2 Java 11 / Java 17

Summary

By default Groovy is not included within any release of Java. Due to this it means that you would need to download the relevant files and place these within Jira/lib. Below are the methods of how to install.

To our knowledge it is currently not possible to install Groovy directly into Java

If you have ScriptRunner installed then you would not need to include these files within jira-install/lib as JEMH is able to utilise the Groovy version that is bundled within ScriptRunner.

Install into Jira/lib

Java 8

Download the Groovy distribution (must contain an embeddable runtime .jar file) - https://archive.apache.org/dist/groovy/3.0.0-alpha-1/distribution/apache-groovy-binary-3.0.0-alpha-1.zip
Extract the contents of the zip file
Copy ./groovy-3.0.0-alpha-1/embeddable/groovy-all-3.0.0-alpha-1.jar and place within <jira_install_directory>/lib folder

Java 11 / Java 17

Currently this method is not working correctly with Java 17 within JEMH 4.1.2+, as it is resulting in an exception when scripting features are used. We will update this page with the fixed version.

Download the Relevant Groovy files, can be downloaded by using the following:
1. wget https://repo1.maven.org/maven2/org/apache/groovy/groovy/4.0.17/groovy-4.0.17.jar wget https://repo1.maven.org/maven2/org/apache/groovy/groovy-xml/4.0.17/groovy-xml-4.0.17.jar wget https://repo1.maven.org/maven2/org/apache/groovy/groovy-jsr223/4.0.17/groovy-jsr223-4.0.17.jar
  Note: Updated above links to download the current latest Groovy version.
Copy these downloaded files into <jira_install_directory>/lib folder
Restart Jira

Once installed you should then see that Groovy is listed as a Detected Script Engine within JEMH > Extensions > Detected Script Engines.
