How can I get the current git branch in gradle?
提问by neptune
I'm writing a task to deploy my application to the server. However, I'd like for this task to run only if my current git branch is the master branch. How can I get the current git branch?
我正在编写一个任务来将我的应用程序部署到服务器。但是，我希望此任务仅在我当前的 git 分支是主分支时运行。如何获取当前的 git 分支？
gradle-gitapproach:
gradle-git方法：
I know there is a gradle-git pluginthat has a method getWorkingBranch()under the task GitBranchList, but anytime I try to execute
我知道有一个gradle-git 插件getWorkingBranch()在任务下有一个方法GitBranchList，但任何时候我尝试执行
task getBranchName(type: GitBranchList) {
print getWorkingBranch().name
}
I get a "Task has not executed yet" error. I looked at the sourceand it throws that error when there is no branch set. Does that mean this method doesn't do quite what I think it does? That I need to set the branch somewhere?
我收到“任务尚未执行”错误。我查看了源代码，当没有设置分支时，它会抛出该错误。这是否意味着这种方法不像我认为的那样做？我需要在某处设置分支吗？

You also are able to get git branch namewithout the plug-in.
您也可以在git branch name没有插件的情况下获得。
def gitBranch() {
def branch = ""
def proc = "git rev-parse --abbrev-ref HEAD".execute()
proc.in.eachLine { line -> branch = line }
proc.err.eachLine { line -> println line }
proc.waitFor()
branch
}

No this doesn't mean that the branch is not set. It means that the task hasn't really executed yet. What you're trying to do is calling a method in the configuration closure, whereas you probably want to call it after task execution. Try to change your task to:
不，这并不意味着没有设置分支。这意味着任务还没有真正执行。您要做的是在配置闭包中调用一个方法，而您可能希望在任务执行后调用它。尝试将您的任务更改为：
task getBranchName(type: GitBranchList) << {
print getWorkingBranch().name
}
With the <<you're adding a doLast, which will be executed after the task has been executed.
随着<<您添加一个 doLast，它将在任务执行后执行。
