Need Groovy syntax help for generating a Closure from a String

Question

I\'m trying to generate a closure from a string. The code inside the closure references a DSL function build(). The errors I\'m getting imply that Groovy is trying to exec

Answer 1

Consider the example below. The key is to specify, explicitly, a closure without parameters.

def build = { def jobName ->
    println "executing ${jobName}"
}

// we initialize the shell to complete the example
def sh = new GroovyShell()
sh.setVariable("build", build)

// note "->" to specify the closure
def cl = sh.evaluate(' { -> build("my job") }')

println cl.class
cl.call()
