Paul King commented on GROOVY-7773:
-----------------------------------
I have cloned this issue. Firstly, I think we should at least support Java's
syntax in this case (to be covered by this issue) by allowing a semi-colon to
close off the constant declarations (with or without the dangling comma - but
optional for the non-dangling case). Secondly, in the cloned issue, we can
explore whether it is possible to tweak the grammar to remove that need, i.e.
make it optional for the dangling case too if possible.
> Enum constructor with value throws "unexpected token" error

> Key: GROOVY-7773
> URL: https://issues.apache.org/jira/browse/GROOVY-7773
> Project: Groovy
> Issue Type: Bug
> Components: Compiler
> Affects Versions: 2.4.6
> Environment: Windows 7 Professional
> JDK 1.8.0_45
> Reporter: Brian Ray
> Priority: Minor
>
> First time submitter to this JIRA so let me know if I've specified anything
> incorrectly. I just upgraded from 2.4.4 to 2.4.6 and now declaring an enum
> constructor accepting a value as follows:
> {code:title=UsStates.groovy}
> enum UsState {
>
> ID('Idaho'),
> IL('Illinois'),
> IN('Indiana'),
>
> UsState( String value ) { this.value = value }
> private final String value
>
> String toString() { return value }
> }
> println UsState.ID //Idaho
> {code}
> throws the following compile error:
> {code}
> org.codehaus.groovy.control.MultipleCompilationErrorsException: startup
> failed:
> C:\svn_qa\jenkins_trunk\scripts\UsStates.groovy: 7: unexpected token: this @
> line 7, column 29.
> UsState( String value ) { this.value = value }
> ^
> 1 error
> {code}
> No such error occurred in 2.4.4, nor does it happen in 2.4.5. Here are a few
> contrasting things that do seem to work in 2.4.6:
> {code:title=UsStatesBoring.groovy}
> enum UsState {
>
> ID,
> IL,
> IN,
> }
> println UsState.ID //ID
> {code}
> {code:title=UsStatesNoEnum.groovy}
> class UsState {
>
> UsState( String value ) { this.value = value }
> private final String value
>
> String toString() { return value }
> }
> final idaho = new UsState('Idaho')
> println idaho //Idaho
> {code}
> Though this seems higher priority than Minor, I can work around it by simply
> downgrading to 2.4.5. I wish there was a Medium priority.
