"Cannot run Project.afterEvaluate" crash when Gretty applied to a Gradle sub-module via plugins block

[chris-hatton]

When applying Gretty 3.0.4 via the plugins {} block only to a Gradle 7.0.2 project sub-module, the following error is thrown:

An exception occurred applying plugin request [id: 'org.gretty', version: '3.0.4']
> Failed to apply plugin 'org.gretty'.
   > Cannot run Project.afterEvaluate(Closure) when the project is already evaluated.

• The same crash does not occur if the Gretty plugin is applied only to the root project.
• The same crash does not occur if the Gretty plugin is applied to both the root project and sub-project.
• The crash does occur if the Gretty plugin is applied to the root project with apply false and applied to the sub-project.

In brief; it looks like the Gretty plugin must be fully applied to the root project to work. This seems an unintended and unreasonable restriction.

@chris-hatton - please try 3.0.5. It should work fine. Also, please open issues in the new repo. :)
