[GRADLE-2259] extra property and extension name clash is detected late Created: 30/Apr/12  Updated: 10/Feb/17  Resolved: 10/Feb/17

Status: Resolved

Consider the following:

apply plugin: 'eclipse'
ext.eclipse = ['gradle': 'is awesome']

//no longer possible:
eclipse.project.name = 'my project'

Above is just an example, there are cases where creating extra property that matches existing extension name may lead to runtime failures.

At minimum we should fail fast if someone overrides existing extension with an extra property (IMHO)

We should deal with all kinds of collisions.

I think the order of precedence for resolving a property or method should be:

  • Built-in property or method
  • Task (or more generally, an element in the current container)
  • Extension
  • Convention object
  • Extra property

That is, extensions should win over extra properties.

As far as collision handling goes, we can either warn or fail when a collision is detected. Detection can happen either when the property is accessed, or when the task/extension/extra property is defined. If we do the detection at definition time, we have to deal with ordering to some degree, as an extra property can be defined before or after the extension that it collides with is defined.

We'd also need to deal with some of the intentional collisions we have, for example, where we have both an 'eclipse' task and an 'eclipse' extension for a given Project object.
