What is the usage of Maven pom.xml - <tag> element inside of <scm> when you are using git
提问by mjlee
We are using maven and git together for a Java project. In <scm>section, <tag>is automatically added by release plugin.
我们正在将 maven 和 git 一起用于 Java 项目。在<scm>节中，<tag>由发布插件自动添加。
For example,
例如，
<scm>
<connection>scm:git:http://myserver:7990/scm/project/test.git</connection>
<tag>releaes-tag</tag>
</scm>
What does <tag>represent here?
<tag>这里代表什么？
I believe the normal convention is <tag>HEAD</tag>.
我相信正常的约定是 <tag>HEAD</tag>.
When we were using subversion, maven never used <tag></tag>
当我们使用 subversion 时，maven 从未使用过 <tag></tag>
What is the meaning of <tag></tag>?
是什么意思<tag></tag>？
I searched google and maven documentation but I cannot find any information on it.
我搜索了 google 和 maven 文档，但找不到任何相关信息。

The <tag>element is used by release:prepareto specify the tag that was created for this release (implemented as MRELEASE-723). Outside of a release it is essentially a placeholder, and HEADis an appropriate value.
该<tag>元素用于release:prepare指定为此版本创建的标记（实现为MRELEASE-723）。在发布之外，它本质上是一个占位符，并且HEAD是一个合适的值。

<tag></tag>
当我们使用 subversion 时，maven 从未使用过
<tag></tag>
As MRELEASE-723explains:
正如MRELEASE-723解释：
when I invoke release:prepare with a URL like:
https://example.test/svn/REPO/myproject/branches/releaseit will be replaced byhttps://example.test/svn/REPO/myproject/tags/myproject-1.0which is fine because now you know which revision to checkout for building the release.
当我使用如下 URL 调用 release:prepare 时：
https://example.test/svn/REPO/myproject/branches/release它将被替换为https://example.test/svn/REPO/myproject/tags/myproject-1.0which 很好，因为现在您知道要检出哪个修订版以构建发布。
The <scm>element for a release build should contain enough information to check out the tag that was created for this release.
<scm>发布版本的元素应该包含足够的信息来检查为此发布创建的标签。
Subversion allows the tag to be included in the connection URL. Neither Git nor Mercurial allow this, so the <tag>element is used instead.
Subversion 允许将标记包含在连接 URL 中。Git 和 Mercurial 都不允许这样做，因此使用该<tag>元素代替。
