googlevr sdkを使用してビルドが単一化に失敗し、クラスをdexに変換できません

google-vr sdkを使用して空想のためにビルドしようとしていますが、Unityでビルドエラーが発生します。plugins / androidディレクトリを削除するとビルドできますが、ビルドは地獄のようにバグがあります。次に、不足している依存関係をインストールするように求められます：GVRBackwardsCompatibilityのインポート

そうすると、クラスをdex形式に変換できず、再度ビルドできなくなります。コンソールはこれを示しています：

 CommandInvokationFailure: Unable to convert classes into dex format.

Unity 5.6.0b1 // Google VR SDK 1.10 // win10 x64

プラグイン/ Androidのmanifest.xmlを変更してtarget-sdkを反映させ、Unityエディターで変更してみました

どんな助けでも大歓迎です。
