我可以使用在多模块项目中定义的自定义生命周期吗？

Question

我有一个具有复杂生命周期的项目，因此自定义生命周期是有意义的。 但是，我希望能够在同一多模块构建的插件中定义生命周期。 该插件仅定义了自定义生命周期（在components.xml ）。

apollo-server-parent
  - apollo-server-lifecycle-plugin
    - src/main/resources/META-INF/plexus/components.xml (defines apollo-server-product)
  - ApolloServer
    - pom.xml

... <packaging>apollo-server-product</packaging> ... <plugin> <groupId>ca.nanometrics.apollo</groupId> <artifactId>apollo-server-lifecycle-plugin</artifactId> <version>${project.parent.version}</version> <extensions>true</extensions> </plugin>

但是，如果我这样做，将无法构建Maven，因为它无法找到apollo-server-lifecycle-plugin，因为在构建反应堆时尚未构建它。 关于如何解决此问题的任何想法？ 我是否必须在单独的项目中定义插件？

我得到的错误示例：

[ERROR] Some problems were encountered while processing the POMs:
[ERROR] Unresolveable build extension: Plugin ca.nanometrics.apollo:apollo-server-plugin:4.0.0-SNAPSHOT or one of its dependencies could not be resolved: Could not find artifact ca.nanometrics.apollo:apollo-server-plugin:jar:4.0.0-SNAPSHOT in releases (http://.../nexus/content/groups/public) @

如果我在这里没弄错你-

您要构建ApolloServer模块，该模块使用apollo-server-lifecycle-plugin也是项目的一个模块。

当前的项目结构为：

apollo-server-parent
  - apollo-server-lifecycle-plugin
  - ApolloServer

---

从多模块指南中 ，一种简单的方法可以确保始终在ApolloServer模块之前构建apollo-server-lifecycle-plugin 。 最简单的方法是在ApolloServer(pom.xml)中包含apollo-server-lifecycle-plugin的依赖关系，这将确保Reactor排序首先构建插件。

插件对构建中另一个模块的依赖
