Adding enableAggregatingTask breaks build

Versions:

• Android Studio: 4.2.1
• AGP: 4.2.1
• Dagger: 2.37

We have a Kotlin Multiplatform Module called common, which is then referenced from Android and iOS. In the Android app we include this common module. The app builds fine without the following code in build.gradle:

hilt { enableAggregatingTask = true }

As soon as I add it, the next build after the Gradle sync fails with the following error:

Could not determine the dependencies of task ':android:app:hiltJavaCompileRtvNoordDebug'.
> Could not resolve all task dependencies for configuration ':android:app:hiltCompileOnlyRtvNoordDebug'.
   > Could not resolve project :common.
     Required by:
         project :android:app
      > The consumer was configured to find attribute 'com.android.build.api.attributes.BuildTypeAttr' with value 'debug', attribute 'omroep' with value 'rtvNoord'. However we cannot choose between the following variants of project :common:

          - debugRuntimeElements

          - iosRuntimeOnly

        All of them match the consumer attributes:

        The following variants were also considered but didn't match the requested attributes:
          - Variant 'prereleaseApiElements' capability nl.stichtingrpo.news.common:common:1.0:
              - Incompatible because this component declares attribute 'com.android.build.api.attributes.BuildTypeAttr' with value 'prerelease' and the consumer needed attribute 'com.android.build.api.attributes.BuildTypeAttr' with value 'debug'
              - Other compatible attribute:
                  - Doesn't say anything about omroep (required 'rtvNoord')
          - Variant 'prereleaseRuntimeElements' capability nl.stichtingrpo.news.common:common:1.0:
              - Incompatible because this component declares attribute 'com.android.build.api.attributes.BuildTypeAttr' with value 'prerelease' and the consumer needed attribute 'com.android.build.api.attributes.BuildTypeAttr' with value 'debug'
              - Other compatible attribute:
                  - Doesn't say anything about omroep (required 'rtvNoord')
          - Variant 'releaseApiElements' capability nl.stichtingrpo.news.common:common:1.0:
              - Incompatible because this component declares attribute 'com.android.build.api.attributes.BuildTypeAttr' with value 'release' and the consumer needed attribute 'com.android.build.api.attributes.BuildTypeAttr' with value 'debug'
              - Other compatible attribute:
                  - Doesn't say anything about omroep (required 'rtvNoord')
          - Variant 'releaseRuntimeElements' capability nl.stichtingrpo.news.common:common:1.0:
              - Incompatible because this component declares attribute 'com.android.build.api.attributes.BuildTypeAttr' with value 'release' and the consumer needed attribute 'com.android.build.api.attributes.BuildTypeAttr' with value 'debug'
              - Other compatible attribute:
                  - Doesn't say anything about omroep (required 'rtvNoord')

omroep is a flavor, which is set to rtvNoord in the current build variant. nl.stichtingrpo.news.common:common is the package of the common module. Is this new setting not compatible with the 4.x versions of AGP or Kotlin Multiplatform? Let me know if you need any more info for resolving this.

@eric-labelle you seem to be having a different issue, can you file a new bug and share more information about your setup? Like your build.gradle and a trace running Gradle with --stacktrace.

Closing as the fix for this was released in 2.38
