Error running 'JeecgSystemApplication': Command line is too long. Shorten command line for JeecgSystemApplication or also for Spring Boot default configuration.

1、idea run时报“ Error running ‘JeecgSystemApplication’: Command line is too long. Shorten command line for JeecgSystemApplication or also for Spring Boot default configuration?”

翻译：运行“JeecgSystemApplication”时出错：命令行太长。缩短JeecgSystemApplication或Spring引导默认配置的命令行？
解决方案：
（1）点击"run"-> “edit configuration”

（2）找到"Environment"->“Shorten command line”，并选择下拉列表中的"JAR manifest"
（3）点击"Apply"->"OK"即可

2、导入项目后无法进行"Run"操作，可能是由于idea没帮忙下载依赖导致的，点击idea右侧的“Maven”，点击下图按钮重新更新项目依赖，即可看到出现"Run"按钮。
