Mac 上 IntelliJ Idea 2019.2 运行的时候出现了一个红色的警告:
objc[2248]: Class JavaLaunchHelper is implemented in both /Library/Java/JavaVirtualMachines/jdk1.8.0_77.jdk/Contents/Home/bin/java (0x108a364c0) and /Library/Java/JavaVirtualMachines/jdk1.8.0_77.jdk/Contents/Home/jre/lib/libinstrument.dylib (0x108ab04e0). One of the two will be used. Which one is undefined.
解决方法：
在idea中，进行修改idea.properties
1.打开idea --> 工具栏Help --> Edit Custom Properties...
2.添加以下配置：
idea.no.launcher=true
3.重启idea就可以了
