How to Install Groovy Software

There are two common ways to install Groovy in your system.

(1) Download : The Groovy binary can be downloaded on the download page of the Groovy website. You can unpack archeve and add path to %GROOVY_HOME% /bin/groovy.bat to the PATH system environment variable, here %GROOVY_HOME%  is the directory where Groovy is unpacked.

These instructions describe how to install a binary distribution of Groovy:

  • Download a binary distribution of Groovy and unpack it into some folder on your local file system.

  • Set your GROOVY_HOME environment variable to the directory where you unpacked the distribution.

  • Add GROOVY_HOME/bin to your PATH environment variable.

  • Set your JAVA_HOME environment variable to point to your JDK. On OS X this is /Library/Java/Home, on other unixes its often /usr/java etc. If you’ve already installed tools like Ant or Maven you’ve probably already done this step.

You should now have Groovy installed properly. You can test this by typing the following in a command shell:

groovysh

Which should create an interactive groovy shell where you can type Groovy statements. Or to run the Swing interactive console type:

groovyConsole

To run a specific Groovy script type:

groovy Helloworld.groovy
