Maven 多模块发布
Posted
技术标签:
【中文标题】Maven 多模块发布【英文标题】：Maven Multi Module Release 【发布时间】：2016-08-25 10:01:11 【问题描述】：所以，我无法理解发生了什么。 我有一个这种结构的项目：
Aggregator Pom
|
+- Parent Pom
|
+- SubModule 1 (whose parent is "Parent Pom")
|
+- SubModule 2 (whose parent is "SubModule 1")
都是pom包装。
我这几天一直在与发布插件作斗争。我运行了一个版本，它成功地部署到了 maven Central。但是，Parent Pom、SubModule 1 和 SubModule 2 的版本是下一个 snapshot 版本。
它是由 TeamCity 执行的，但基本上它运行的是这样的：
mvn -P sign-artifacts -B release:clean release:prepare --batch-mode -Dtag=0.1.0 -DreleaseVersion=0.1.0 -DdevelopmentVersion=0.2.0-SNAPSHOT -Dscm.tag=0.1.0 -Dproject.rel.aggregator pom groupId:aggregator pom artifactId=0.1.0 -Dproject.dev.aggregator pom groupId:aggregator pom artifactId=0.2.0-SNAPSHOT
然后：
mvn -P sign-artifacts -B release:perform -P sign-artifacts
（“sign-artifacts”配置文件负责 GPG 签名）
在 maven Central 中，我看到 Parent Pom、SubModule 1 和 SubModule 2 在那里，它们的元数据显示它们的版本是 0.1.0，但是当我下载每个的 pom 时，我看到版本是 0.2.0-SNAPSHOT .
任何想法什么是错的，以及如何解决？
提前致谢，
天啊

关于.m2，这是一个构建代理；它得到一个新的.m2 ...
有什么想法吗？
【问题讨论】：
找到根本原因； maven scm 插件中的错误 【参考方案1】：嗯……在你的解释中我不太清楚……
首先我认为在这种情况下项目结构不是问题......
通常的行为是：
-
我有一个项目 1.0-SNAPSHOT..
我使用 maven 发布插件发布它..
这被标记为 1.0 并提交到 tags 文件夹中
然后将主干\分支版本增加为 1.1-SNAPSHOT..
看来您正在下载主干版本，并且正在将标记版本检查到远程存储库中......
这是对的吗？
如果不是，那是某种与插件执行有关的奇怪版本，你能检查一下 SVN 标签，告诉我那里的 pom 是哪个版本，以及创建标签的提交的注释?
这两个命令的输出也可以帮助理解发生了什么......
Lat 的东西，可能不相关，但是您是否将工件下载到 .m2 本地存储库中，您可以清理它并重试吗？这不是 .m2 第一次做一些奇怪的事情了 :)
【讨论】：
ivoroJavaBoy，感谢您的回复。我不认为你建议的场景是正确的。以下是一些输出： [13:10:33][INFO] 检查项目以执行发布...
