Description

Some method call expressions are parsed differently in 1.8 compared to 1.7. This causes one of Gradle's AST transforms to fail. According to Jochen, this looks like a bug in the 1.8 ANTLR grammar.

task copy(type: Copy) { x = 10 }
g1.7: this.task(this.copy(...))
g1.8: this.task(this.copy(...))

task copy(type: Copy) { println 10 }
g1.7: this.task(this.copy(...))
g1.8: task.copy(...)

The first expression is parsed the same in 1.7 and 1.8, but the second expression is parsed differently.
