How to execute shell command from Java code on GCP
问题
我的目标非常简单：
我想从位于Google Cloud Platform上（在我这个案例中是App Engine）的Java代码中执行一个shell命令（例如"pwd"）。
在本地，我可以通过ProcessBuilder或者Runtime.getRuntime().exec(...)来实现。
问题是，当我尝试在需要执行这种操作的GCP上部署Java服务时，它失败并显示错误：
java.io.IOException: 无法运行程序"pwd"：error=2，没有那个文件或目录
我尝试了以下方法：
Runtime.getRuntime().exec(new String[]{"bash", "-l", "-c", "pwd"}, null);
这种方法在本地也能工作，但在GCP上仍然失败。
有人知道怎么解决吗？

My goal is pretty simple:
I wan't to execute a shell command (e.g. "pwd") from java code that is on Google Cloud Platform (App Engine in my case).
Locally i'm capable of doing so either by a ProcessBuilder or Runtime.getRuntime().exec(...).
The thing is that when I'm trying to deploy a Java service on GCP that needs to do that, it fails with the error:
java.io.IOException: Cannot run program "pwd": error=2, No such file or directory
I tried working this out with:
Runtime.getRuntime().exec(new String[]{"bash", "-l", "-c", "pwd"}, null);
Which also works locally, but on GCP it still fails.
Anyone?
