Applying IDEA plugin to multi-project Java build throws spurious (?) deprecation warnings with Gradle 2.4

Bugs

Applying the IDEA plugin to this trivial Gradle multi-project build yields a barrage of spurious (?) deprecation warnings of the form: “Attempting to change configuration {foo} after it has been included in dependency resolution. This behaviour has been deprecated and is scheduled to be removed in Gradle 3.0”?

Run:

   mkdir -p parent/child

Set contents of parent/settings.gradle:

   include 'child'

Set contents of parent/build.gradle:

   allprojects {
       apply plugin: 'idea'
       apply plugin: 'java'

       repositories {
           mavenCentral()
       }

       dependencies {
           compile 'com.google.guava:guava:18.0'
       }
   }

Set contents of parent/child/build.gradle:

   dependencies {
       compile 'com.orientechnologies:orientdb-graphdb:2.0.8'
   }

Run:

   gradle wrapper --gradle-version 2.4

Run:

   ./gradlew --refresh-dependencies clean cleanIdea cleanIdeaWorkspace idea build

Witness output:

   This build could be faster, please consider using the Gradle Daemon: http://gradle.org/docs/2.4/userguide/gradle_daemon.html
