Description

@groovy.transform.Field i = 5

assert getProperty("i") == 5 // ok
assert i == 5 // ok

setProperty("i", getProperty("i") + 1)

assert getProperty("i") == 6 // ok
assert i == 6 // fails, i is currently 5

Effectively

• script.getProperty did read script.i field
• while script.setProperty stored value only to Binding, not to script.i field

Please consider script.setProperty to detect that there is script.$name field, and if there is, write there and only there to match getProperty behavior.
