Regarding breaking out of the each loop see: is it possible to 'break' out of a groovy closure

Basically you have to throw and exception and catch it. The "break" keyword is only allowed inside loops not iterated "closures" (really code blocks).

You can use any complex code with "find" just make sure the function you call returns a Boolean. For example:

Boolean test(val) {
    println "Testing $val"
    return val == 1
}

def found = [3,4,5,1,6,3].find { test(it) }

println "Found $found"
