Android Studio Error:library dependencies that have been compiled using Java 8 or above
问题
Android studio 编译项目时报以下错误
Error:Error converting bytecode to dex:
Cause: Dex cannot parse version 52 byte code.
This is caused by library dependencies that have been compiled using Java 8 or above.
If you are using the 'java' gradle plugin in a library submodule add
targetCompatibility = '1.7'
sourceCompatibility = '1.7'
to that submodule's build.gradle file.
Error:1 error; aborting
:app:transformClassesWithDexForDebug FAILED原因
经过各种排查，发现是因为导入了一个类库导致
compile 'com.google.guava:guava:21.0'
应该是由于该库是基于java7编写的，而我的项目是基于java8，导致了冲突
解决
不用该库，或降低java版，目前google还没有好的解决方法
