Question

我有以下两个maven项目

pom.xml (parent)

-

pom.xml (aggregate, extends parent)
|
|--pom.xml (module, extends aggregate)

仅定义工件版本的位置是父级。其他项目或其模块直接或间接从父级继承该版本。我想自动将聚合版本及其模块版本与父版本匹配。

我升级了父版本和mvn install之后，我正在尝试使用 versions-maven-plugin 来升级聚合项目，并将其模块设置为与新父级匹配命令：

mvn versions:update-parent versions:update-child-modules clean install

正确升级父级和模块父级，但安装目标仍会在版本-maven-plugin 所做的更改之前安装该版本。如果我想安装升级版本，我必须在mvn clean install插件后单独调用versions。为什么install不在同一命令中选择versions插件所做的更改？我还尝试包含versions:commit但没有效果。这是构建日志以显示正在发生的事情。

Answer 1

Maven在之后运行版本插件它已经解析了所有依赖版本，因此无法再调用它两次。一旦更新版本，然后构建项目。

maven执行阶段在this SO answer中得到了很好的解释。特别参见第7步。

Maven：版本：update-parent，然后是install installs旧版本
