Maven：在不扩展依赖关系的情况下使用拼合来解决版本

问题描述 投票：1回答：1

我想在构建后解析所有修订标签，所以我正在使用flatten。我有一个这样的多模块项目：

A (root)
|_B (parent = A, dependencyManagement with version = ${revision}
|_C (parent = B, dependencies declared in dependencyManagement without specifying the version)

问题是，在B的平整pom中，${revision}无法解析。此外，在扁平化的C的pom中仍然缺少该版本，而我希望可以找到B中的dependencyManagement中声明的版本。

这是我配置展平的方式：

    <build>
        <plugins>
            <plugin>
                <groupId>org.codehaus.mojo</groupId>
                <artifactId>flatten-maven-plugin</artifactId>
                <version>1.1.0</version>
                <configuration>
                    <updatePomFile>true</updatePomFile>
                    <flattenMode>resolveCiFriendliesOnly</flattenMode>
                </configuration>
                <executions>
                    <execution>
                        <id>flatten</id>
                        <phase>process-resources</phase>
                        <goals>
                            <goal>flatten</goal>
                        </goals>
                    </execution>
                    <execution>
                        <id>flatten.clean</id>
                        <phase>clean</phase>
                        <goals>
                            <goal>clean</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
        </plugins>
    </build>

我试图在<configuration>中添加此部分：

<pomElements>
    <dependencyManagement>expand</dependencyManagement>
    <dependencies>expand</dependencies>
</pomElements>

这部分解决了问题，因为它解决了所有版本，但是pom变得太冗长，因为它扩展了父级的所有依赖关系。因此，结果是C的平整pom显式包含了B e A中声明的所有依赖项，以及B的dependencyManagement。

是否有一种方法可以解决版本而不扩展子pom中的所有依赖项？

我解决了此问题，为仅包含<flattenMode>bom</flattenMode>部分的模块将<configuration>添加到dependencyManagement部分中。

根据Maven Flatten Plugin Documentation

选项bom与ossrh类似，但另外保留了dependencyManagement和属性。特别是它将保持dependencyManagement不变而不解决父级影响和导入范围的依赖关系。如果您的POM代表BOM（物料清单），并且您不想按原样部署（删除父级并解析版本变量等）。

您可以在下面看到一个示例
