Интеграция Azure AD B2C в пример github для Android

Question

Я импортировал пример проекта azure ad b2c из github в android studio и получил эту ошибку сборки.

Кто-нибудь знает, в чем проблема?

Cannot choose between the following variants of project :library:
  - debugRuntimeElements
  - releaseRuntimeElements
All of them match the consumer attributes:
  - Variant 'debugRuntimeElements' capability net.openid:library:86437:
      - Unmatched attributes:
          - Found com.android.build.api.attributes.BuildTypeAttr 'debug' but wasn't required.
          - Found com.android.build.api.attributes.VariantAttr 'debug' but wasn't required.
          - Found com.android.build.gradle.internal.dependency.AndroidTypeAttr 'Aar' but wasn't required.
          - Found org.gradle.usage 'java-runtime' but wasn't required.
  - Variant 'releaseRuntimeElements' capability net.openid:library:86437:
      - Unmatched attributes:
          - Found com.android.build.api.attributes.BuildTypeAttr 'release' but wasn't required.
          - Found com.android.build.api.attributes.VariantAttr 'release' but wasn't required.
