我有一个多模块 Maven 项目。每个库模块都会生成自己的 jar 输出：

Parent (Pom)
   |
   Library_01 (jar)
   |   output:
   |     |
   |     lib1.jar
   |     |
   |     lib1-docs.jar
   |     |
   |     lib1-sources.jar
   |
   Library_02 (jar)
   |   output:
   |     |
   |     lib2.jar
   |     |
   |     lib2-docs.jar
   |     |
   |     lib2-sources.jar
   |
   Distribution (pom) // uses assembly plug-in to assemble outputs of other modules here
       output:
         |
         lib1.jar
         |
         lib2.jar

我正在分发模块中组装其他模块的二进制文件，完全按照此处maven-assembly-plugin的文档中的说明。我的 POM 看起来与教程中的完全一样。

它按照文档中显示的方式工作。在打包阶段，程序集插件在分发模块中收集其他模块的 jar。但正如您所见，其他库模块也被配置为生成文档和源 jar。

  1. 如何配置程序集插件以收集其他模块的文档和源 jar？

  2. 考虑分布，上面的设置似乎不合适。我最终还是得到了一堆用于不同库的罐子。可以将所有其他模块的类、源代码和文档各自组合成一个 jar 文件吗？基本上，我想要分发 3 个全局 jar（二进制、文档和源）。如何实现？

         |
         Global-docs.jar (contains docs of Lib1 + Lib2)
         |
         Global-sources.jar (contains sources of Lib1 + Lib2)

好吧，我不是专家，但我也在多模块项目中做类似的事情。这是一个父母的 pom 片，其中指定了插件和文档：

好的，我已经通过以下选项：

  1. maven-assembly-plugin：构建组合二进制文件，也可能是源，但没有 javadocs。而且，非常复杂。
  2. maven-shade-plugin：非常容易构建组合的二进制文件和源代码，但没有 javadocs。此外，源文件名很难控制。

所以，我采取的简单方法如下：

确保所有模块都生成源 jar。这可以通过在父 pom 中启用源插件来完成，该插件由所有模块继承：

<build>
    <plugins>
        <plugin>
            <inherited>true</inherited>
            <artifactId>maven-source-plugin</artifactId>
            <executions>
                <execution>
                    <id>attach-sources</id>
                    <goals>
                        <goal>jar</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>
    </plugins>
</build>

创建一个特殊的“构建”模块来组合所有其他模块的源。这是通过使用带有源分类器maven-dependency-plugin的目标来完成的。unpack-dependencies这意味着将所有其他模块源合并为该模块的源。

构建模块的 pom：

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

                </executions>
                <configuration>
                    <classifier>sources</classifier>
                    <type>jar</type>
                    <outputDirectory>${project.build.sourceDirectory}</outputDirectory>
                    <includeArtifactIds>${project.build.unpack_includes}</includeArtifactIds>
                    <includes>**\/*.java</includes>
                    <overWriteSnapshots>true</overWriteSnapshots>
                </configuration>
            </plugin>
            <plugin>
                <artifactId>maven-javadoc-plugin</artifactId>
                <executions>
                    <execution>
                        <id>attach-javadocs</id>
                        <goals>
                            <goal>jar</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
        </plugins>
    </build>

</project>

现在，构建模块像任何其他项目一样编译，生成所有需要的 jar。
