我正在运行一个颠覆服务器、一个 TeamCity 服务器和一个 Youtrack 服务器。目前，这些都是相互关联的，这意味着每当我提交某些内容时，我都会在提交消息中添加一个 youtrack 问题编号，并且该变更集会出现在 Youtrack 中的问题下，在 TeamCity 作为中间人的帮助下。我现在想要实现的是阻止所有与 youtrack 中的未解决问题无关的提交。

我在其他版本控制系统和票证管理系统中看到了类似的功能。我注意到 Youtrack 有一个 rest api 接口，所以这可能是（一部分？）解决方案。

我最终自己实施了一个解决方案。

基本上，预提交挂钩是一个小程序，它要么以 0 退出（这样提交被接受）要么以另一个值退出（这样提交被拒绝。

我编写了一个批处理脚本，该脚本调用一个可运行的 jar，该 jar 登录到 Youtrack rest api 并获取提交消息中提到的票证的所有详细信息。如果该票存在，并且它具有我们希望它具有的状态，则 java 应用程序以值 0 退出，导致批处理脚本以相同的值退出并接受提交。另一方面，如果出现问题，java 应用程序会以另一个值退出，从而导致提交被拒绝。

我的可视 SVN 存储库的批处理文件如下：

@set echo off
setlocal enabledelayedexpansion

rem Subversion sends through the path to the repository and transaction id  
set REPOS=%1  
set TXN=%2           
rem get the commit message from svn server
for /f "delims= " %%a in ('"C:\Program Files\VisualSVN Server\bin\svnlook" log %REPOS% -t %TXN%') do (
@set COMMIT_MSG=%%a
rem call the java jar that performs the api call to match the commit message against an open ticket
java -jar C:\Users\Administrator\Desktop\Repositories\MyProject\hooks\preCommitHook-with-dependencies.jar !COMMIT_MSG!
rem if java returns System.exit(0) then we accept the commit. Otherwise print out a failure message and decline it.
echo !COMMIT_MSG! 1>&2
echo !errorlevel! 1>&2
if !errorlevel! gtr 0 (goto err) else exit 0  
)

:err
echo ===================================================================== 1>&2
echo Your commit has been rejected. This is because the issue you assigned 1>&2
echo on it does not exist or is not "In Progress" state. Please try again. 1>&2  
echo ===================================================================== 1>&2
exit 1

至于 Java，有两件有趣的事情：一是执行所有其余调用的类本身，二是我们制作 JAR 以包含所有依赖项的 pom.xml。
