AndroidStudio 编译异常java.lang.OutOfMemoryError: GC overhead limit exceeded

Android Espresso - java.lang.OutOfMemoryError: GC overhead limit exceeded

最近开发过程中经常会碰到这样的问题，度娘google不少，发现能真正解决的没几个，有些人说jar冲突，有些说是内存配置过小，有些说是jdk版本不对，各种各种的回答都有，但没办法解决这问题，具体会报如下错误：

:Project:dexFlavorEnterpriseDebug FAILED

一碰到这样就脑袋大，错误无从下手，终于在google有人回答了这个，在build.gradle中的android{}添加如下脚本就可以顺利编译了

dexOptions {

incremental true

javaMaxHeapSize “4g”

}
