java - Maven 构建顺序(多个模块)

Question

这个问题在这里已经有了答案:

Build order of Maven multimodule project? (4 个回答)

关闭 5年前。

我有一个 Maven 父项目，它有多个子/模块...我有以下 pom.xml 作为主/父项目；

<modules>
        <module>Main-Ear</module>
        <module>Sub-Web</module>
        <module>Sub-Ui</module>
        <module>Sub-Services</module>
        <module>Sub-SSO-Login</module>
  </modules>

但是，我发现实际的构建顺序有所不同...构建后，实际顺序如下:

Main
Sub-Services
Sub-SSO-Login
Sub-UI
Sub-Web
Main-Ear

在这种情况下，Maven 究竟从哪里获取构建顺序？

您无法手动控制构建顺序:

来自 Maven 项目文档 (Guide to Working with Multiple Modules):

Reactor Sorting

Because modules within a multi-module build can depend on each other, it is important that The reactor sorts all the projects in a way that guarantees any project is built before it is required.

The following relationships are honoured when sorting projects:

• a project dependency on another module in the build
• a plugin declaration where the plugin is another modules in the build
• a plugin dependency on another module in the build
• a build extension declaration on another module in the build the order declared in the element (if no other rule applies)

Note that only "instantiated" references are used - dependencyManagement and pluginManagement elements will not cause a change to the reactor sort order
