Gradle on Mac installed using MacPorts: where is Gradle home?

Question

I installed Gradle using MacPorts and now I am unable to find where the Gradle home is. For example Eclipse asks me for the location and I have no idea:

I tried specifying the path obtained from which gradle:

$ which gradle
/opt/local/bin/gradle

But it does not work. So, where is the Gradle home?

Answer 1

It turns out that MacPorts tells you the Gradle home when installing / upgrading Gradle. The installation log ends with the following:

--->  Some of the ports you installed have notes:
  gradle has the following notes:
    Remember to set the environment variable GRADLE_HOME 
    to the path to the gradle distribution:
    /opt/local/share/java/gradle

So the correct Gradle home in that case is:

/opt/local/share/java/gradle

And this works in the Eclipse scenario mentioned above.
