我正在使用2.1的版本versions-maven-plugin。
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)
如上所述，<parent />项目的customs-template为customs-deployment-support。所有其他<parent />项目的customs-*-template为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项，但它确实将customs-*个项目声明为<module /> <modules /> 1}}部分。
对于SNAPSHOT版本的构建，这非常有用。
现在，我想转移到versioned个工件，其中每个工件的版本签名都类似于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，我配置了一个前步骤，以便在每个海关项目的<parent />部分中使用类似的东西进行跳汰：
mvn versions:update-parent
我希望它能找到Nexus中可用的最新上游工件（即base-parentpom和customs-parentpom）。
但它失败了......

考虑到我绝不希望Jenkins在上述情况下生成SNAPSHOT版本工件。我意识到SNAPSHOT在本地.m2存储库中不可用。我（真的）需要一个版本插件才能正确解析吗？
我做错了什么？是否有可能做我想做的事情？如果有帮助，我愿意分享pom.xml文件。
答案 0 :(得分：0)
所以这只是我的一个误解。如果您使用多模块设置，则需要确保在签出源代码时，为了构建模块，它必须能够将其路径追溯到parent（通过{{1 }}）。
我正在检查一个模块，但不是它的父项;因此我得到了<relativePath />错误。
因此，为了让reactor发挥作用，您需要在聚合器（和/或父代）non-resolvable parent POM中定义所有模块。
然后你可以构建一个（或多个）模块（项目），如此
pom.xml
