Mac 上idea启动程序 “Class JavaLaunchHelper is implemented in both 。。。”错误解决

今天更新最新版本IntelliJ IDEA时遇到

Class JavaLaunchHelper is implemented in both

错误，大致是：

objc[99623]: Class JavaLaunchHelper is implemented in both /Library/Java/JavaVirtualMachines/jdk1.8.0_91.jdk/Contents/Home/bin/java (0x1015e54c0) and /Library/Java/JavaVirtualMachines/jdk1.8.0_91.jdk/Contents/Home/jre/lib/libinstrument.dylib (0x102e5c4e0). One of the two will be used. Which one is undefined.

解决办法：

点击IntelliJ IDEA上面菜单的”Help”下的“Edit Custom Properties”，在文件中加上

idea.no.launcher=true

重启再试

PS:若没有idea.properties文件，则点击“Edit Custom Properties”会提示创建一个，再在里面加入idea.no.launcher=true
