动态传参给json时只传递了部分参数

通过shell执行datax抽数命令并动态传参给json配置文件,总共有6个参数,只传递了3个参数,另外3个参数json文件没有接收到,在打印的信息中还是显示的${xxx}.而有时执行时又成功了,能接受到所有参数.

Start by reproducing the shell execution that passes six parameters to the JSON configuration, comparing runs where only three placeholders are replaced with runs where all six are received. Trace the parameter-substitution entry point and verify completion when every parameter is consistently resolved instead of remaining as ${xxx}.
