Telling the intellij debugger to re-position break-point information

Answered

I have this code transformation of a .groovy file using AST transformations.

@AddExtraParam
def func1() {
someRandomFunction()
}

def func2() {
func1()
}

is converted to

@AddExtraParam
def func1(MyCustomInjectedParam _custom) {
injectCodeToSomethingWith(_custom)
someRandomFunction()
}

def func2() {
func2(new MyCustomInjectedParam())
}

This will compile fine with my ASTTransformation for AddExtraParam. But now if I set a breakpoint in intellij inside func1, it will not hit because the signature has changed. However if I place my breakpoint inside func2, it will hit and everything will work as expected as far as debugging goes

The question I have is this

I just want to tell IDEA that my breakpoint is at a different spot in a different function. How do I do this?

It should work out of the box as long as line numbers are correct. Please check generated `LineNumberTable` in compiled class file.

Daniil,

You are absolutely right. Thank you for the response. I figured out what is happening but am at a loss for how to fix it.

I am using a groovy AST to wrap all code in my function. This happens without the IDE knowing about it because it happens at runtime. Therefore when I setup my breakpoint, it thinks the breakpoint is at file Flow.groovy:23 but at runtime, because the closure is a separate class, the breakpoint really needs to be in another closure class at a different location. Per the IDE. The first image is before I started to debug. Notice that a closure in the script shows breakpoint info reflecting the same file name. But during debug, the breakpoint is actually in a diffferent class/location. How does Groovy achieve this? I possibly need to do something similar right?

Do I need to extend the GroovyPositionManager to help it understand that the breakpoint is really pointing to a different class file? Can you point me to the code that does this today for closures in the groovy plugin?
