Order of configure closure binding changed between Gradle 1.8 and 2.0

I’m trying to migrate from Gradle 1.8 to 2.0 and noticed an intricate change in behavior of the DSL.

The following snippet demonstrates the change:

class SimpleDomainObject
    String name
          public SimpleDomainObject(String name)
                this.name = name
      void methodInSimpleDomainObject() {
        println "methodInSimpleDomainObject called for object '$name'"
  extensions.add('container', project.container(SimpleDomainObject))
  container {
    repositories {
  println 'Objects in container: ' + container*.name

Executing this code in Gradle 1.8 prints:

methodInSimpleDomainObject called for object 'repositories'
Objects in container: [repositories]

Executing it in Gradle 2.0:

Build file 'build.gradle' line: 19
  * What went wrong:
A problem occurred evaluating root project 'closurebinding'.
> Could not find method methodInSimpleDomainObject() for arguments [] on repository container.

This only occurs if the name of the domain object is a method in an enclosing closure delegate (like in this case the project). This is pretty suprising.

Digging through the changes, the culprit seems to be changes to ConfigureDelegate: http://code-review.gradle.org/changelog/Gradle/?cs=cf0af3757a35aed8801acccd5110d15935482058

Even more surprising: If you omit the call to methodInSimpleDomainObject, both versions yield the same result. But then there is no object created in the container!

Objects in container: []

I see, why the new behavior in Gradle 2.0 is more reliable than the behavior in 1.8. I’m still not convinced however, why one would want to call a configure-method, i.e. a method call with a single closure parameter, onto an object in some outer scope instead of creating a new object in the directly surrounding container.

Maybe you can reconsider and give the delegate precedence over the owner for all closure-like methods. If not, you should at least document this as potential breaking change in Gradle 2.0, as it is very hard to find and investigate.
