Description

« Hide

Parentheses cannot be omitted for methods starting with capital letter. MultipleCompilationErrorsException is raised during compilation. I would guess that the bug was introduced with 1.5.2, but I haven't checked it out. It has worked before anyway.

Example:

def AMethod(s) {
    println s
}
def anotherMethod(s) {
    println s
}
AMethod('groovy1') //Ok
anotherMethod 'groovy2' //Ok
AMethod 'groovy3' //compile time exception

org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed, Script18: 9: unexpected token: groovy3 @ line 9, column 9.
1 error

I doubt it is introduced in 1.5.2 I think this issue was already in 1.0

I just tried it in 1.5.1, and it worked fine. It definitely worked in 1.0.

In groovy 1.0 through 1.5.1, what you have works but something like this fails:

// instead of AMethod 'groovy3'
def baz = 'groovy3'
AMethod baz

It fails because it is being treated as a method definition.

I think Groovy 1.5.2+ is also treating this additional case as a method definition (an incomplete one I guess).
