FAILURE: Execution failed for task ':findMainClass'.

[puneetbehl]

Expected Behavior

The scaffolded code is generated as:

> Task :findMainClass

> Task :runCommand
Grails application running at http://localhost:0 in environment: development
Rendered template Controller.groovy to destination grails-app/controllers/com/example/BirdController.groovy
Rendered template Service.groovy to destination grails-app/services/com/example/BirdService.groovy
Rendered template Spec.groovy to destination src/test/groovy/com/example/BirdControllerSpec.groovy
Rendered template ServiceSpec.groovy to destination src/test/groovy/com/example/BirdServiceSpec.groovy
| Scaffolding complete for grails-app/domain/com/example/Bird.groovy

Actual Behaviour

Creating a new Grails web application with Grails Gradle Plugin 6.2.0 throws the following error when we execute the Gradle task to generate scaffolding code for a domain class, as:

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':findMainClass'.
> 'java.util.List org.codehaus.groovy.runtime.DefaultGroovyMethods.findAll(java.lang.Object[], groovy.lang.Closure)'

* Try:
> Run with --info or --debug option to get more log output.
> Run with --scan to get full insights.

* Exception is:

Steps To Reproduce

1. Create a new Grails Web application from https://start.grails.org.
2. Unzip and open in an IDE(IntelliJ).
3. Edit/Update buildSrc/build.gradle, and update the dependency for Grails Gradle Plugin, as:

• implementation("org.grails:grails-gradle-plugin:6.2.0")
  

4. Create a simple domain class. For example:

• package demoapp
  
  class Book {
      String title
  }
  

5. Execute the following Gradle task to generate scaffolded controller:

• ./gradlew runCommand -Pargs="generate-controller demoapp.Book"
