我正在努力弄清楚如何从Gradle运行shell命令,因为Gradle似乎很难做到这一点。
这是命令:
git branch --merged | grep -v \* | grep -v master | grep -v develop | grep -v dmz | xargs git branch -D
这只是一个方便的命令来清理已合并的本地分支。
这是我创建的任务:
task gitCleanLocalBranches {
doLast {
exec {
workingDir '.'
commandLine 'git branch --merged | grep -v \\* | grep -v master | grep -v develop | grep -v dmz | xargs git branch -D'
}
}
}
任务失败:
FAILURE: Build failed with an exception.
* What went wrong:
Execution failed for task ':gitCleanLocalBranches'.
> A problem occurred starting process 'command 'git branch -a''
* Try:
Run with --info or --debug option to get more log output.
* Exception is:

所以我认为命令太复杂了,所以我尝试了更简单的方法,并将commandLine
更改为:
commandLine 'git branch -a'
但是我得到了完全相同的错误。为什么Gradle无法在PATH
环境变量中找到任何内容?
答案 0 :(得分:11)
要执行的命令及其参数必须是单独的参数才能传递给commandLine
,如下所示:
commandLine 'git', 'branch', '-a'
如果您想执行第一个示例中的复杂管道, 你可以将它包装在shell脚本中。
我无法测试这一点,但我认为这也应该有效:
commandLine 'sh', '-c', 'git branch --merged | grep -v -e \* -e master -e develop -e dmz | xargs git branch -D'
注意:我冒昧地简化了grep
。
最后,您还可以在.gitconfig
中创建一个Git别名来包装复杂的管道。

如果需要保存命令输出,可以执行以下操作:
def gitBranchA = "git branch -a".execute().text.trim()
