Android 无法在OSX中使用gradle--retrolambda生成项目

我是OSX的新手。今天我尝试在Android Studio中使用RxJava和Retrolambda，Retrolambda需要gradle——Retrolambda

所以我开始配置：

1.我在~/.bash_配置文件中粘贴了一些代码，以设置JAVA7_HOME和JAVA8_HOME

export JAVA7_HOME=/Library/Java/JavaVirtualMachines/jdk1.7.0_79.jdk/Contents/Home   
export PATH=$JAVA_HOME/bin:$PATH 
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar

export JAVA8_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_60.jdk/Contents/Home 
export PATH=$JAVA_HOME/bin:$PATH 
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar

PATH="/Library/Frameworks/Python.framework/Versions/3.4/bin:${PATH}"
export PATH

它似乎工作良好，我检查它使用终端

echo $JAVA8_HOME
/Library/Java/JavaVirtualMachines/jdk1.8.0_60.jdk/Contents/Home
echo $JAVA7_HOME
/Library/Java/JavaVirtualMachines/jdk1.7.0_79.jdk/Contents/Home

然后我跟着别人的文章

2.编辑的Android Studio->首选项->路径变量 增加了“JAVA8_HOME”和“JAVA7_HOME”，同上

3.编辑的build.gradle（项目）

4.编辑的build.gradle（应用程序）

我遵循了这个建议，因为gradle retrolambda的官方建议找不到Java8，所以这个问题很有效

但它给了我：

我处理不了这件事。有人能帮我吗？非常非常感谢：）

尝试将所有.java文件移动到根包中。这对我很有用

这就是我配置OSx环境的方式

安装最新的Java8

编辑.bash_配置文件（位于主目录中）并添加以下行：

export JAVA_HOME=

/usr/libexec/JAVA_HOME

export JAVA7_HOME=

/usr/libexec/java_HOME-v1.7

*现在“java-version”命令必须显示Java1.8，但retrolambda也可以访问Java7主目录

将以下行添加到project build.gradle文件：

依赖关系{ ... 类路径“我。塔塔卡：格拉德尔·兰博达：3.2.5” classpath'com.neenbedankt.gradle.plugins:android apt:1.8'

将retrolambda插件应用于android应用程序模块build.gradle：

应用插件：“me.tatarka.retrolambda”

*无需向该模块添加编译依赖项
