下面是我app.gradle應用插件:「com.android.application」無法在Android Studio中更新到Java 8
apply plugin: 'realm-android'
android {

我收到以下錯誤,而同步gradle這個: 錯誤:無法獲取用於com.android.build.gradle.internal.pipeline.TransformTask類型的任務'app:transformJackWithJackForDebug'的未知屬性'classpath'。
這有點誇大其詞。 [retrolambda](https://github.com/orfjackal/retrolambda)將使OP僅支持lambdas和方法引用。這也應該可以通過「官方」Android Studio工具鏈來實現,* Jack *(現已棄用)和[desugar](https://developer.android.com/studio/preview/features/java8-support.html#supported_features) 。當你還需要一些新的Java 8 API(比如Streams)並且同時想要'minSdkVersion <24'時,事情會變得更有趣。如果minSdkVersion是24或更高,我會建議去* desugar *。 –
不知道。感謝您的建議,似乎我應該馬上得到desugar。 –
