Error translating mvel script to groovy

Question

While preparing for an update to elasticsearch 2.0, I noticed mvel scripting is being deprecated in favor of groovy. My problem is that I am new to groovy and don't know how to fix this error.

boolean engineTest = false; if (!engineTest) { engineTest = true;} return engineTest;

This throws the following error

unexpected token: return @ line 1, column 68. [...]

why don't you just return true ? – Pierre-Olivier Nov 12 '15 at 20:31 — Pierre-Olivier, Nov 12 '15 at 20:31
Maybe a better example next time? ;-) – tim_yates Nov 12 '15 at 21:08 — tim_yates, Nov 12 '15 at 21:08

If it all needs to be on 1 line, then you're missing a semi-colon before the return statement. As in:

boolean engineTest = false; if (!engineTest) { engineTest = true}; return engineTest;

Otherwise, you could split the statements on 3 lines and avoid all semi-colons.

Thank you. I didn't realize my code was executing inline! – Danny Nov 12 '15 at 21:13
