IDEA报错：java: Compilation failed: internal java compiler error

具体有：

查看项目的jdk（Ctrl+Alt+shift+S）

File ->Project Structure->Project Settings ->Project

查看工程的jdk（Ctrl+Alt+shift+S）

File ->Project Structure->Project Settings -> Modules -> （需要修改的工程名称） -> Sources

查看idea中Java配置

File ->Setting ->Build,Execution,Deployment -> Compiler -> Java Compiler

修改堆大小

File ->Setting -->Build,Execution,Deployment-->Compiler 中找到build process heap size(Mbytes):700改为1024或者8192
