How to specify JVM for Groovy

Question

What JVM uses Groovy be default and how to specify another version?

Output from my server:

$ groovy --version Groovy Version: 2.4.5 JVM: 1.7.0_95 Vendor: Oracle Corporation OS: Linux $ java -version java version "1.8.0_05" Java(TM) SE Runtime Environment (build 1.8.0_05-b13) Java HotSpot(TM) 64-Bit Server VM (build 25.5-b02, mixed mode)

Answer 1

You've probably got JAVA_HOME pointing to the Java 7 jdk

If you unset it with

unset JAVA_HOME

Groovy should use the default JVM, the same as Java
