AS 3.1中编译失败

[chenfei0928]

在AS 3.1.0 中，添加依赖之后，Sync成功，编译失败，这是相关日志
Exception in thread "main" java.lang.NullPointerException: Couldn't find outer class com/exyui/android/debugbottle/components/DTDrawerActivity$infoLayout$2$1$1 of com/exyui/android/debugbottle/components/DTDrawerActivity$infoLayout$2$1$1$1 at com.google.common.base.Preconditions.checkNotNull(Preconditions.java:1079) at com.google.devtools.build.android.desugar.ClassVsInterface.isOuterInterface(ClassVsInterface.java:56) at com.google.devtools.build.android.desugar.InterfaceDesugaring.visitOuterClass(InterfaceDesugaring.java:246) at org.objectweb.asm.ClassReader.accept(ClassReader.java:638) at org.objectweb.asm.ClassReader.accept(ClassReader.java:500) at com.google.devtools.build.android.desugar.Desugar.desugarClassesInInput(Desugar.java:477) at com.google.devtools.build.android.desugar.Desugar.desugarOneInput(Desugar.java:361) at com.google.devtools.build.android.desugar.Desugar.desugar(Desugar.java:314) at com.google.devtools.build.android.desugar.Desugar.main(Desugar.java:711)

请问您是否使用了Java8?

[lichen228]

仅在gradle3.1.0下出现，gradle3.0.1可以正常编译
classpath 'com.android.tools.build:gradle:3.1.0'

在3.1.0下脱糖失败：
Run tasks :app:transformClassesWithDesugarForDevDebug

infoLayout的写法，为保证编译，作者是不是考虑先取消Lambada

启用了Java8语法支持
