[英]Git Diff command in Java
For a project, I need to take a list of git commit Id's (A couple thousand), and compare them two at a time, saving specific information from the return into a file. 对于一个项目,我需要列出git commit Id的列表(几千个),然后一次将它们两个进行比较,将返回的特定信息保存到文件中。 The only issue I'm having is getting a diff command to work in Java.
我唯一遇到的问题是让diff命令在Java中工作。 I've spend hours trying to figure this out and I'm still in need of assistance.
我已经花了数小时试图解决这个问题,但我仍然需要帮助。
You can run a command and get its result using this : 您可以运行命令并使用以下命令获取结果:
ProcessBuilder processBuilder = new ProcessBuilder(command);
processBuilder.redirectErrorStream(true);
Process process = processBuilder.start();
String output = readOutput(process);
try {
if (process.waitFor() != 0) {
throw new IOException(
"command exited in error: " + process.exitValue()
+ "\n" + output);
}
} catch (InterruptedException e) {
e.printStackTrace();
}
return output;
So you just have to define the most adapted "git diff..." command for your problem and parse the output. 因此,您只需要为您的问题定义最适合的“ git diff ...”命令并解析输出。
