最近看到github上出现了VirtualApp 看了作者的介绍感觉很不错，然后就clone下来编译并研究一下，但是编译过程出现了如下错误提示，看着有些头疼
由于VirtualApp是需要将提供的android.jar和sdk里面的jar替换这里就省略….

编译错误提示

1: Task failed with an exception.-----------* What went wrong:Execution failed for task ':app:compileDebugJavaWithJavac'.> When running gradle with java 5, 6 or 7, you must set the path to jdk8, either with property retrolambda.jdk or environment variable JAVA8_HOME* Try:Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.==============================================================================2: Task failed with an exception.-----------* What went wrong:A problem was found with the configuration of task ':app:compileRetrolambdaDebug'.> Directory '/Users/cuiran/git/VirtualApp/VirtualApp/app/build/retrolambda/debug' specified for property 'inputDir' does not exist.* Try:Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.==============================================================================

根据错误提示
首先，需要安装Jdk1.8 然后设置jdk1.8环境变量
然后，在android studio->Preferences->Path Variables添加
如图所示

最后需要在build.gradle中添加代码

 retrolambda {        jdk '/Library/Java/JavaVirtualMachines/jdk1.8.0_102.jdk/Contents/Home'//System.getenv("JAVA_8")        oldJdk System.getenv("JAVA8_HOME")        javaVersion JavaVersion.VERSION_1_7    }

这样就可编译通过!
