idea 错误: 找不到或无法加载主类 @C:\Users\admin\AppData\Local\Temp\idea_arg_file1549212448

该错误往往和左下角爱弹出的如下提示是一个意思

Error running 'PayV3Test1.testTransferBatchesBatchId' Error running PayV3Test1.testTransferBatchesBatchId. Command line is too long. Shorten the command line via JAR manifest or via a classpath file and rerun.

解决方案

1、点击IDEA右上角的执行配置 "Run/Debug Configurations"

2、选中执行配置项，修改Shorten command line 为 "JAR manifest" 或者 "classpath file"，保存配置重新执行即可
