java - 如何将 sourceCompatability 设置为 javaVersion.VERSION_1_8

Question

我安装了jdk1.8.0_112，在build.gradle中写了下面的代码

 compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }

我收到这个错误

Error:Jack is required to support java 8 language features. Either enable Jack or remove sourceCompatibility JavaVersion.VERSION_1_8.

谁能帮帮我？

来自 https://developer.android.com/guide/platform/j8-jack.html ，您还需要以下内容:

  defaultConfig {
    ...
    jackOptions {
      enabled true
    }
  }
