[jira] [Commented] (GROOVY-10750) Compiler does not resolve compile-time constants in string concatenation

["Christopher Smith (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/GROOVY-10750?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17645026#comment-17645026 ] 

Christopher Smith commented on GROOVY-10750:
--------------------------------------------

For some reason I had thought this was fixed (and it works in at least some circumstances), but I just got tripped up by it again. Is this likely to be resolvable in 4.x? I certainly understand difficulties if inference is involved, but in cases where I can affirmatively declare {{public static final String}}, it would be nice for annotations to compile.

Specifically, it appears that references to external string constants defined _on a Groovy interface_ (but in a different jar) work fine, but references to identically shaped constants on a Java interface produce this error.

> This appears to be the same behavior marked as fixed in GROOVY-9855. In a Groovy 4.0.4 compilation, this code:
> {code}
> @CompileStatic
> @RequestMapping(path = FooController.BASE_URL)
> class FooController {
>   public static final String BASE_URL = '/foos'
> }
> @CompileStatic
> @RequestMapping(path = FooBarController.BASE_URL)
> class FooBarController {
>   public static final String BASE_URL = FooController.BASE_URL + '/{fooId}/bars'
> }
> {code}
> succeeds for FooController, but FooBarController produces a pair of errors:
> {code}
> FooBarController.groovy: 20: Expected 'com.example.FooBarController.BASE_URL' to be an inline constant of type java.lang.String not a property expression in @org.springframework.web.bind.annotation.RequestMapping
> FooBarController.groovy: 20: Attribute 'path' should have type 'java.lang.String'; but found type 'java.lang.Object' in @org.springframework.web.bind.annotation.RequestMapping
> {code}
