Java ProcessBuilder返回退出错误128，在Linux中执行git（一些git命令可以正常工作）

Question

Simple git command i try to execute with java ProcessBuilder , working find when i run it in linux with results returned. this is the command :

git -C /home/mlxx log -1 "72xxxxxxxxe700d6bbe06" --pretty=format:"%s"

when i try to execute it in java

ProcessBuilder pb = new ProcessBuilder()
                    .command("git","-C","/home/mlxx","log","1","72xxxxxxxxe700d6bbe06","--pretty=format:\"%s\"").directory("/bin/bash");

The int exit = p.waitFor(); returns 128 error code

now according to this link : Start GitLog with Java Process Builder which face the same problem

i tried to do :

ProcessBuilder pb = new ProcessBuilder()
                        .command("/usr/bin","-c""git","-C","/home/mlxx","log","1","72xxxxxxxxe700d6bbe06","--pretty=format:\"%s\"")

The int exit = p.waitFor(); returns 1 error c0de

what is wrong here ?

other commands working just fine in linux via java?

Answer 1

You are specifying /bin/bash as the process's working directory:

[...] .directory("/bin/bash");

This is an executable file and not a valid directory.

You can leave it off entirely, since you already specify the directory git should operate on with its -C option.
