使用 Google Cardboard VR 构建 .apk 存档时出错

Question

我正在尝试使用 Unity 5.6 和 Google Cardboard 构建我的 VR 项目。我收到以下错误

CommandInvokationFailure: Unable to convert classes into dex format.
/Library/Java/JavaVirtualMachines/jdk1.8.0_131.jdk/Contents/Home/bin/java -Xmx2048M -Dcom.android.sdkmanager.toolsdir="/Users/mymac/Library/Android/sdk/tools" -Dfile.encoding=UTF8 -jar "/Applications/Unity/PlaybackEngines/AndroidPlayer/Tools/sdktools.jar" -

环顾四周，发现可能是.jar/.aar文件重复错误，所以我在我的项目中寻找：

mymac$ find . | grep .aar
./Assets/Plugins/Android/gvr-permissionsupport-release.aar
./Assets/Plugins/Android/gvr-permissionsupport-release.aar.meta
./Temp/StagingArea/aar
./Temp/StagingArea/aar/gvr-permissionsupport-release.aar
./Temp/StagingArea/aar/gvr.aar
./Temp/StagingArea/aar/unitygvr.aar

mymac$ find . | grep .jar
./Assets/Plugins/Android/unityvractivity.jar
./Assets/Plugins/Android/unityvractivity.jar.meta
./Temp/StagingArea/android-libraries/gvr/libs/classes.jar
./Temp/StagingArea/android-libraries/gvr-permissionsupport-release/libs/classes.jar
./Temp/StagingArea/android-libraries/unitygvr/libs/classes.jar
./Temp/StagingArea/bin/classes.jar
./Temp/StagingArea/plugins/libprotobuf-java-nano.jar
./Temp/StagingArea/plugins/unityvractivity.jar

您可以看到没有重复，因为所有其他文件都是在构建时在 /Temp 中创建的副本。不知道如何继续。

修复了从项目中移除 GoogleVR 插件的问题。即使 bash 控制台没有显示，也不知何故存在重复。
