How do I redirect output to stderr in groovy?

Question

I'm looking for a way to redirect output in a groovy script to stderr:

catch(Exception e) {
    println "Want this to go to stderr"
}

Answer 1

Just off the top of my head couldn't you do a bit of self-wiring:

def printErr = System.err.&println printErr("AHHH") 

but that is a bit manual

Answer 2

Groovy has access to the JRE:

System.err.println "goes to stderr" 

Although there may be a more Groovy-fied way...

Answer 3

Another quite compact alternative is this:

System.err << "Want this to go to stderr"

Or you could add this at the top of your script

def err = System.err
...
err << "Want this to go to stderr"

which is what I'm now doing in my groovy shell scripts
