Missing DefaultGroovyMethods.collect on startup of Grails 3.3.16 app with Gorm-MongoDB 7.0.2

[seanhastings]

Background

When trying to upgrade the Mongo GORM plugin to the latest 7.0.x on Grails version 3.3.16, running the application gives the following error on startup:

***************************
APPLICATION FAILED TO START
***************************

Description:

An attempt was made to call the method org.codehaus.groovy.runtime.DefaultGroovyMethods.collect([Ljava/lang/Object;Lgroovy/lang/Closure;)Ljava/util/List; but it does not exist. Its class, org.codehaus.groovy.runtime.DefaultGroovyMethods, is available from the following locations:

    jar:file:/Users/shastings/.gradle/caches/modules-2/files-2.1/org.codehaus.groovy/groovy/2.4.21/abbb8d83268f3243a57d9f7768e159373a4e378/groovy-2.4.21.jar!/org/codehaus/groovy/runtime/DefaultGroovyMethods.class

It was loaded from the following location:

    file:/Users/shastings/.gradle/caches/modules-2/files-2.1/org.codehaus.groovy/groovy/2.4.21/abbb8d83268f3243a57d9f7768e159373a4e378/groovy-2.4.21.jar

It seems that the List collect(Object, Closure) method can't be found, but I can see it in the decompiled source of that class, so I'm not sure what's going wrong here. I've tried deleting the Gradle cache mentioned and allowing it to rebuild, but still get the same error afterward.

Recreation Steps

1. Create a clean 3.3.16 Grails application.
   grails create-app
2. Add the Mongo GORM dependency to build.gradle
compile 'org.grails.plugins:mongodb:7.0.2'
3. Run the application
   grails run-app
