Question

i have this simple code

def values = [foo:5, bar:6]  

def result = Eval.me("p", values, "${p.foo}+${p.bar}")

why it doesn’t work ?

i get a:

groovy.lang.MissingPropertyException: No such property: p for class: ConsoleScript7

Thanks for the help.

Answer 1

The Strings in your Groovy expression aren’t surrounded with double quotes, so Groovy isn’t treating them as a GString with expression support. Adding escaped double quotes around the expression and escaping the $ will give you a working result.

Eval.me("p", values, "\"\${p.foo}\"+\"\${p.bar}\"")

Also, you could to one of the following, depending on if you want to output a String or and integer value:

Eval.me("p", values, "p.foo.toString()+p.bar.toString()")

or

Eval.me("p", values, "p.foo+p.bar")
