错误信息

在将playwright部署到linux容器中的时候，总是报下面的错误：

单步调试

经过单步调试，发现playwright初始化的时候，会有如下操作：

  1. 将当前jar包中的依赖库driver-bundle-1.20.1.jar解压到临时目录
  2. 再读取解压好的driver-bundle-1.20.1.jar，以便找到playwright的驱动。

问题就出在第一步，解压出去的jar包不可用，虽然大小还是一样的，但是格式错误，无法当作zip解压。

如下，不可解压：

解决方案

深层次的原因暂时没有精力排查，目前的解决方案是重新打jar包，将所有的lib依赖放到外面。
这样在拷贝文件的时候，就不会出现解压错误。
