【问题描述】：
我使用的是versions-maven-plugin 的2.1 版本。
我有一个如下所示的源代码树：
+-- JavaProjects
+-- customs-deployment-support
+-- pom.xml
+-- pom.xml (a.k.a. base-parentpom)
+-- Projects
+-- customs-template
+-- pom.xml
+-- customs-ear-template
+-- pom.xml
+-- customs-rpm-template
+-- pom.xml
+-- customs-site-template
+-- pom.xml
+-- pom.xml (a.k.a. customs-parentpom)
现在上面，customs-template 项目的<parent /> 是customs-deployment-support。所有其他customs-*-template 项目的<parent /> 是base-parentpom。
注意：customs-parentpom 只是一个“聚合器”，并不是任何海关模块的真正父级，但它确实在其<modules /> 部分中将每个customs-* 项目声明为<module />。
对于SNAPSHOT 版本的构建，这很好用。
现在，我想转到 versioned 工件，其中每个工件的版本签名类似于 x.x.x_yyyyMMddhhmm_nn。
所以，现在我想使用versions-maven-plugin 来构建customs-parentpom（或“聚合器”pom.xml）
我使用 Jenkins 进行构建。因此，我配置了一个前置步骤，以在每个海关项目的 <parent /> 部分中调整版本，例如：
mvn versions:update-parent
我希望它找到 Nexus 中可用的最新上游工件（即 base-parentpom 和 customs-parentpom）。
但它失败了......

考虑到在上述情况下，我从不希望 Jenkins 生成 SNAPSHOT 版本工件。我意识到 SNAPSHOT 在本地 .m2 存储库中不可用。我（真的）需要一个才能正确解析版本插件吗？
我做错了什么？甚至有可能做我想做的事吗？如果有帮助，我愿意分享 pom.xml 文件。
