How to force Groovy Script Engine to output compiled classes in files?

Question

I googled and found out you can make GroovyScriptEngine output scriptCache into class files by setting setTargetDirectory. But when I execute the code something like below from scala, it doesn't generate class files.

How do you set GroovyScriptEngine to output class files from scripts compiled by GroovyScriptEngine?

var gse = new GroovyScriptEngine()
gse.getConfig().setTargetDirectory("c:/test")
var scriptClass = gse.loadScriptByName("SomeGroovyClass.groovy")

Answer 1

The GroovyScriptEngine does not seem ( from looking at the source ) to use that property of CompilerConfiguration

It would need to be passed in the constructor of the inner ScriptClassLoader , so that the GroovyClassLoader that it extends gets the configuration when it is constructed.
