idea 启动shorten command line too long 错误解析

因为项目启动的命令行太长了经常是带一些vm参数或者一些依赖jar
idea提供了三种方式

Select a method that will be used to shorten the command line if the classpath gets too long or you have many VM arguments that exceed your OS command line length limitation:
none: IntelliJ IDEA will not shorten a long classpath. If the command line exceeds the OS limitation, IntelliJ IDEA will be unable to run your application and will display a message suggesting you to specify the shortening method.

JAR manifest: IntelliJ IDEA will pass a long classpath via a temporary classpath.jar. The original classpath is defined in the manifest file as a class-path attribute in classpath.jar. Note that you will be able to preview the full command line if it was shortened using this method, not just the classpath of the temporary  classpath.jar.

classpath.file: IntelliJ IDEA will write a long classpath into a text file.

User-local default: this legacy option is set automatically for projects created before IntelliJ IDEA version 2017.3. IntelliJ IDEA will configure this setting depending on the properties set in the  ide/workspace.xml and idea.config.path/options/options.xml files.

This setting is shared if you select to share your run/debug configuration, so the same method will be applied for your team members irrespective of their operating system.

none 是不改变启动命令行
jar manifest是合并内容到manifest后启动
classpath 是通过把参数封装进文件后启动
