本文解决IDEA运行控制台出现的objc错误提示，详细解释了ClassJavaLaunchHelper在两个位置实现导致的问题，并提供了解决方案，通过编辑自定义属性idea.no.launcher设置为true来避免此问题。

ideal运行控制台打印如下内容：

objc[3087]: Class JavaLaunchHelper is implemented in both /Library/Java/JavaVirtualMachines/jdk1.8.0_131.jdk/Contents/Home/bin/java (0x102a414c0) and /Library/Java/JavaVirtualMachines/jdk1.8.0_131.jdk/Contents/Home/jre/lib/libinstrument.dylib (0x102ac54e0). One of the two will be used. Which one is undefined.

解决方法：

1.Help--》Edit Custom Properties

2.在配置文件中添加如下配置：

idea.no.launcher=true

这个错误提示的意思大意是：Class JavaLaunchHelper实现两次。这是Mac 上面Java 的一个老Bug了，会在那些使用了Java Agent 的IDEA 上运行应用时触发，但这个错误对程序的运行是无影响的，可以无视，而且，在Java 9和Java 1.8.152 版本里已经修复了，话虽如此，但是看着飘红酒特不舒服啊！
