Wondering how to run Groovy files in Sublime Text? It’s really quite simple – to create a new build system in Sublime Text go to Tools > Build System > New Build System and copy/paste the code below

{
  "cmd": ["groovy","$file"],
  "selector": "source.groovy",
  "windows":
  {
    "shell": "cmd.exe"
  }
}

Once the build system is saved you should be able to type Ctrl + B to run the code and output to the Sublime console. If nothing happens you may need to go to Tools > Build System and select groovy.

This is extremely handy if you’re creating tests in Grails and want to test things without creating a full test case beforehand, writing/running tests in Grails can be excrutiating and testing within your file can help you spot mistakes much quicker than running test-app and waiting for everyting to compile and output your results.
