Groovy console won't load on Windows 7 x64

Question

I've never worked with Groovy before.

I installed the executable and the latest JDK from the Java website.

I set my system ENV variables JAVA_HOME to C:\Program Files\Java\jdk1.8.0_77 and GROOVY_HOME to C:\Program Files (x86)\Groovy\Groovy-2.4.6\bin.

Console won't load, so I tried to restart my computer. No dice. I tried running GroovyConsole.exe directly from the groovy folder, as well as trying the GroovyConsole.bat file.

It won't work and all of the above are the only solutions I've found online.

Groovy console won't load

I set my system environment JAVA_HOME to C:\Program Files\Java\jdk1.8.0_77 and GROOVY_HOME to C:\Program Files (x86)\Groovy\Groovy-2.4.6\bin

Your GROOVY_HOME variable is incorrect. It should point to the root of your Groovy installation (which is one direct up from bin).

In your case the correct value is GROOVY_HOME C:\Program Files (x86)\Groovy\Groovy-2.4.6

You might also want to consider adding %GROOVY_HOME%\bin to your system path.

Setting up your Groovy environment

1. Unzip the groovy archive to some logical place on your hard drive, I have mine in C:\dev\groovy-2.0.5

2. Set the GROOVY_HOME environment variables. On Windows, follow these steps:

   • Optionally add a new System variable with the name GROOVY_HOME and the value of the directory groovy was installed in (mine is C:\dev\groovy-2.0.5)
   • Start a command prompt, and type "set" and hit return to see that your environment variables were set correctly.

3. Optionally add %GROOVY_HOME%\bin to your system path

4. Try opening groovyConsole.bat by double clicking on the icon in the bin directory of the Groovy distribution.

   • If it doesn't work, open a command prompt, and change to the bin directory and run it from there to see what the error message is.

   • If it is complaining about not finding parts of Groovy, then setting GROOVY_HOME may help

Answer 2

If you set JAVA_HOME before you install Groovy and you use Windows installer then installer handles everything properly. If you've set JAVA_HOME after installing Groovy I would recommend a reinstall.
