BUILD FAILED

目前看，是因为mac上存在多个java版本时调用了低版本的java，或者java版本过低，解决办法是进行mac中不同jdk版本切换

查看默认java版本

javac -version

修改为使用Android Studio中带的java版本不用再重新下载新的jdk了

cat  ~/.bash_profile
export ANDROID_HOME=~/Library/Android/sdk
export JAVA_HOME="/Applications/Android Studio.app/Contents/jre/jdk/Contents/Home"
export PATH=$PATH:$JAVA_HOME:$ANDROID_HOME

然后重启终端，再查看java版本

javac -version
javac 1.8.0_112-release
