Maven Git发布

在开始这篇文章之前，我需要指出我在去年才开始认真地与Git合作。不幸的是，我从事的许多项目仍在使用SVN或CVS，但现在我终于开始使用Git了。

在过去的几年中，我使用Maven Release Plugin完成了许多软件发行。我仍然记得我花了整整一个星期的时间才在我的一个项目中设置插件。在大多数情况下，它都运行良好，但是如果出现问题，您可以花几个小时来解决问题。天哪，噩梦！

最近，我想对Git项目执行相同的操作，并且遇到了Maven JGit-Flow插件，我必须告诉你，这太棒了！设置非常容易，并且在第一次尝试时就可以完美地工作！

该插件基于Vincent Driessen在A成功的Git分支模型一文中描述的开发模型。花点时间阅读它，因为它非常有趣。

我将向您展示如何使用此插件执行发布。我将使用有关Spring Batch的最新文章中的项目作为Wildfly Module 。

设定

设置非常简单，只需将以下内容添加到pom.xml ：

om-jgitflow-maven-plugin.xml

<plugin><groupId>external.atlassian.jgitflow</groupId><artifactId>jgitflow-maven-plugin</artifactId><version>1.0-m3</version><configuration><noDeploy>true</noDeploy></configuration>
</plugin>

我刚刚添加了noDeploy配置，因为我没有发布到Maven存储库。而已！

让我们看看我的项目分支和版本：

分行

radcortez:wildfly-spring-batch radcortez$ git branch -avv

现在，只需运行mvn jgitflow:release-start ：

您将获得一个交互式菜单，以选择要发布的版本号，方法与Maven Release Plugin相同。我开发的master分支，但在这个过程中release分支与发行版本和创建development分支与新开发版本。

发行准备分支

radcortez:wildfly-spring-batch radcortez$ git branch -avvdevelop               728856a [origin/develop] updating poms for 1.1-SNAPSHOT developmentmaster                0b2364b [origin/master] Added documentation.
* release/1.0           9f88a42 updating poms for branch '1.0' with snapshot versionsremotes/origin/master 0b2364b Added documentation.

现在，这很酷的事情是，一切仍在您的本地环境中！如果您对更改不满意，则可以摆脱分支并重新开始。此时未执行构建。

如果要发布，只需运行mvn jgitflow:release-finish ：

释放完成

在此步骤中，将按照A成功的Git分支模型中所述合并release分支并创建标签。记住，什么都没有推送，所以您可以随时还原该过程。

现在让我们看看分支和标签：

分支标签

radcortez:wildfly-spring-batch radcortez$ git branch -avv
* develop               a8e762b [origin/develop] Updating develop poms back to pre merge statemaster                b6fbda0 [origin/master: ahead 3] Merge branch 'release/1.0'remotes/origin/master 0b2364b Added documentation.
radcortez:wildfly-spring-batch radcortez$ git tag
1.0

现在，您可以轻松完成发行，并准备继续在新的更新development分支中进行development 。那有多容易？
