Paul King closed GROOVY-10146.
------------------------------
> Groovy 3 compilation errors are less accurate than Groovy 2
> -----------------------------------------------------------
>
> Key: GROOVY-10146
> URL: https://issues.apache.org/jira/browse/GROOVY-10146
> Project: Groovy
> Issue Type: Improvement
> Components: Compiler
> Affects Versions: 3.0.7, 3.0.8
> Reporter: Sterling Greene
> Assignee: Daniel Sun
> Priority: Minor
> Fix For: 4.0.0-beta-1, 3.0.9
>
>
> Given this broken bit of Groovy code (note the missing single quote after
> Hello):
> {code:groovy}
> class Foo {
> void bar(Closure c) {
> c.call()
> }
> }
> def foo = new Foo()
> foo.bar {
> println 'Hello
> }
> {code}
> In Groovy 2.5.11, the compiler generates a message like:
> {quote}expecting ''', found '\n' at line: 10, column: 19{quote}
> In Groovy 3.0.8, the compiler generates a message like:
> {quote}Unexpected input: '{' at line: 9, column: 9{quote}
> The Groovy 2.x message has identified the right problem (a missing single
> quote), while the Groovy 3.x message is unrelated to the syntax error.
> We see this in Gradle build scripts too. In this broken Gradle script (again,
> a missing single quote):
> {code}
> dependencies {
> testImplementation group: 'junit', name: 'junit', version: '4.12
> }
> {code}
> In Gradle <7 (which uses Groovy 2), the compilation failure says:
> {quote}expecting ''', found '\n' @ line 13, column 69.
> name: 'junit', version: '4.12{quote}
> But in Gradle 7+ (which uses Groovy 3), the compilation failure says:
> {quote}Unexpected input: '{' @ line 12, column 14.
> dependencies {{quote}
> I assume this effects all Groovy 3.x versions, but I only tried 3.0.7 and
> 3.0.8. I also assume the better behavior is the same for all Groovy 2.x, but
> I didn't try any other version.
