应用程序：使用Android Studio 3 canary 1的TransformClassesWithDesugarForMockDebug

Question

我刚从Canary channel安装为3.0，通过从gradle移除lambda插件和添加flavorDimensions添加Java8迁移，这就发生了！：

我的年级档案：

flavorDimensions "environment"
  productFlavors {
    mock {
      dimension "environment"
      applicationIdSuffix = ".mock"
    }
    prod {
      dimension "environment"
      applicationIdSuffix = ".prod"
    }
  }

  // Remove mockRelease
  android.variantFilter { variant ->
    if (variant.buildType.name == 'release' && variant.getFlavors().get(0).name == 'mock') {
      variant.setIgnore(true);
    }
  }

  // Always show the result of every unit test, even if it passes.
  testOptions.unitTests.all {
    testLogging {
      events 'passed', 'skipped', 'failed', 'standardOut', 'standardError'
    }
  }

  compileOptions {
    sourceCompatibility JavaVersion.VERSION_1_8
    targetCompatibility JavaVersion.VERSION_1_8
  }
  lintOptions {
    abortOnError false
  }

  packagingOptions {
    // Remove unneeded Realm native libs
    exclude 'lib/mips/librealm-jni.so'
    exclude 'lib/x86_64/librealm-jni.so'
  }
}

虽然我使用的是RXJava2，但为了解决这个问题，我不得不这样做：

创建如下所示的空虚拟文件：

package rx;

public class Observable {

}
