"Extend" parent pom <build> 在 child pom 中添加一些我想执行的附加插件

Question

我目前使用的 parent <build> 对我 75% 的项目都很方便。
它相当完整。我们称它为 'A' :

    <build>
        <plugins>
            <!-- Bug Eclipse temporaire -->

            </plugin>
        </plugins>
    </build>

然而，从一个子项目开始，对于下面的许多模块，其中 25%，需要通过执行几个插件来扩展它们的 <build>，而 parent pom.xml 应该继续执行。他们在这里，在 'B' 部分：

        <plugins>

                        <configuration>
                            <recompileMode>all</recompileMode>
                            <sourceDir>src/main/scala</sourceDir>
                        </configuration>
                    </execution>
                    
                    <execution>

                        </goals>
                        
                        <configuration>
                            <recompileMode>all</recompileMode>
                            <testSourceDir>${project.basedir}/src/test/scala</testSourceDir>
                        </configuration>
                    </execution>
                </executions>
                
                <configuration>
                    <scalaVersion>${scala.version}</scalaVersion>
                </configuration>
            </plugin>
        </plugins>
    </build>

我希望他们将它们添加到 parent pom 已经执行的其他人中。

如何避免 pom.xml 与 A + B 插件堆叠？我有办法在 child pom.xml 到 'patch' 我的 parent <build> 中使用额外的插件我想要它执行 ?

换句话说，我不想在我的child pom 中有这个：

目前，根据我的所见所闻，在 child pom.xml 中创建 <build> 部分会完全覆盖 [=56= 的 <build> 部分] pom.

Answer 1

您无需重复父 POM 中的任何内容。父子 POM 的构建部分会自动合并，因此在子 POM 中指定附加插件或执行就足够了。

如果您查看有效的 POM（例如通过您的 IDE 或使用 maven 帮助插件），您可以看到 <build> 部分的合并版本。
