$PATH 变量不是通过 getRuntime().exec 继承的 [英] $PATH variable isn't inherited through getRuntime().exec

问题描述

我正在尝试通过以下 Java 命令启动脚本:

I'm trying to start a script by the following command in Java:

proc = Runtime.getRuntime().exec(cmd, null, fwrkDir);

在控制台中输入的命令完美无缺.但是在这里它似乎没有找到脚本，即使它的路径被添加到 $PATH 变量中.如果 null 作为 Environment 传递，Java 不会自动继承所有这些变量吗?

The command, typed in a console, works flawlessly. But here it doesn't seem to find the script, even though it's path is added to the $PATH variable. Doesn't Java automatically inherit all such variables, if null is passed as Environment?

推荐答案

proc = Runtime.getRuntime().exec(cmd, null, fwrkDir);

应该是

proc = Runtime.getRuntime().exec(cmd, "PATH=$PATH:/android-sdk-linux_x86/platform-tools", fwrkDir);
