I'm currently developing a little software in Java and I'm facing a problem I'm not able to solve. In a few words, I am on ArchLinux and I need to run "makepkg" in a specific directory. Of course I tried with
Runtime.getRuntime().exec("cd foo && makepkg");
A process executor is not a shell. It's done for launching a process. A thing that can help you is to launch the process from a specified directory.
You can create a ProcessBuilder instance and set the working directory. It is my way of doing.
ProcessBuilder pb = new ProcessBuilder("makepkg"); pb.directory(new File("foo")); final Process process = pb.start(); // then you read the flow with process.getInputStream() for example
