The Jack toolchain is deprecated and will not run. To enable support for Java 8 language features built into the plugin, remove 'jackOptions { ... }' from your build.gradle file, and add

android.compileOptions.sourceCompatibility 1.8

android.compileOptions.targetCompatibility 1.8

在3.2版本中，注釋掉如下，就可以運(yùn)行了。

defaultConfig {

//? ? ? ? jackOptions {

//? ? ? ? ? ? enabled true

//? ? ? ? }

? ? }
