Git与Gradle版本控制

Question

我正在尝试使用Git在Gradle中实现自动版本控制，但是在构建应用程序时出现了一些错误。我的操作系统是Windows。

def getVerName = { ->
    try {
        def stdout = new ByteArrayOutputStream()
        exec {
            commandLine "git", "describe", "--long"
            standardOutput = stdout
        }
        def result = stdout.toString()
        result = result.trim()
        return result
    } catch (ignored) {
        return null
    }
}

这是我的异常堆栈跟踪

我的GIT路径： C:\Program Files\Git\cmd。将PATH设置为本地变量没有任何作用。从堆栈跟踪中可以看到Gradle正在寻找一个应用程序目录中的git.exe文件。如何更改该路径？

如果你使用git的完整路径会怎样？ - RaGe

请尝试执行以下命令：commandLine "cmd", "/c", "git", "describe", "--long"。 - Opal

@RaGe，全路径工作正常。 - Near1999

Answer 1

如果Gradle在寻找Git的位置时出现问题，建议尝试使用Git可执行文件的完整路径，或者为Exec设置workingDir值。

exec {
  workingDir '../path/to/git/bin'
  commandLine 'cmd', '/c', 'git',...
}

Answer 2

我曾经遇到过同样的问题，但最终发现环境变量中未设置git路径。 我将以下路径添加到PATH变量中，这样就可以正常工作了： C:\Program Files\Git\cmd C:\Program Files\Git\bin\git.exe
