Mac 上idea啓動程序 “Class JavaLaunchHelper is implemented in both 。。。”錯誤解決

今天更新最新版本IntelliJ IDEA時遇到Class JavaLaunchHelper is implemented in both錯誤，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.

解決辦法：
點擊IntelliJ IDEA上面菜單的”Help”下的“Edit Custom Properties”，在文件中加上 idea.no.launcher=true

重啓再試

PS:若沒有idea.properties文件，則點擊“Edit Custom Properties”會提示創建一個，再在裏面加入idea.no.launcher=true
