我可以使用在多模塊項目中定義的自定義生命周期嗎？

Question

我有一個具有復雜生命周期的項目，因此自定義生命周期是有意義的。 但是，我希望能夠在同一多模塊構建的插件中定義生命周期。 該插件僅定義了自定義生命周期（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，如果我這樣做，將無法構建Maven，因為它無法找到apollo-server-lifecycle-plugin，因為在構建反應堆時尚未構建它。 關於如何解決此問題的任何想法？ 我是否必須在單獨的項目中定義插件？

我得到的錯誤示例：

如果我在這里沒弄錯你-

您要構建ApolloServer模塊，該模塊使用apollo-server-lifecycle-plugin也是項目的一個模塊。

當前的項目結構為：

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

---

從多模塊指南中 ，一種簡單的方法可以確保始終在ApolloServer模塊之前構建apollo-server-lifecycle-plugin 。 最簡單的方法是在ApolloServer(pom.xml)中包含apollo-server-lifecycle-plugin的依賴關系，這將確保Reactor排序首先構建插件。

插件對構建中另一個模塊的依賴
