到目前为止，我使用 maven 程序集插件为每个工件生成两个 JAR - 编译源和依赖项 - 原因很简单 - 仅通过网络部署已编译的源比部署 40 MB 的一体机 JAR 快得多数据的。

由于覆盖了内部文件，我不得不切换到 maven shade 插件才能使用该<transformers>功能。但是我无法同时运行这两个执行：

<plugins>
  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-shade-plugin</artifactId>
    <executions>
      <execution>
        <id>shade-libs</id>
        <phase>package</phase>
        <goals>
          <goal>shade</goal>
        </goals>
        <configuration>
          <outputFile>target/assembly/${project.artifactId}-libs.jar</outputFile>
          <artifactSet>
            <excludes>
              <exclude>...</exclude>
            </excludes>
          </artifactSet>
          <transformers>
            <transformer implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">
              <resource>META-INF/spring.handlers</resource>
            </transformer>
            <transformer implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">
              <resource>META-INF/spring.schemas</resource>
            </transformer>
          </transformers>
        </configuration>
      </execution>
    </executions>
  </plugin>
  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-shade-plugin</artifactId>
    <executions>
      <execution>
        <id>shade-main</id>
        <phase>package</phase>
        <goals>
          <goal>shade</goal>
        </goals>
        <configuration>
          <outputFile>target/assembly/${project.artifactId}.jar</outputFile>
          <artifactSet>
            <includes>
              <include>...</include>
            </includes>
          </artifactSet>
        </configuration>
      </execution>
    </executions>
  </plugin>
</plugins>

当我运行时mvn package，只运行第二次执行。第一个总是被忽略。使用 Maven 程序集插件，它工作得很好。

当然解决方案可能是同时使用程序集和阴影插件，但我想找到更一致的解决方案。

不要定义插件两次，只需定义一次但有两个execution部分。因此，在您的情况下，它将是：

<plugins>
  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-shade-plugin</artifactId>
    <executions>
      <execution>
        <id>shade-libs</id>
        <phase>package</phase>
        <goals>
          <goal>shade</goal>
        </goals>
        <configuration>
          <outputFile>target/assembly/${project.artifactId}-libs.jar</outputFile>
          <artifactSet>
            <excludes>
              <exclude>...</exclude>
            </excludes>
          </artifactSet>
          <transformers>
            <transformer implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">
              <resource>META-INF/spring.handlers</resource>
            </transformer>
            <transformer implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">
              <resource>META-INF/spring.schemas</resource>
            </transformer>
          </transformers>
        </configuration>
      </execution>
      <execution>
        <id>shade-main</id>
        <phase>package</phase>
        <goals>
          <goal>shade</goal>
        </goals>
        <configuration>
          <outputFile>target/assembly/${project.artifactId}.jar</outputFile>
          <artifactSet>
            <includes>
              <include>...</include>
            </includes>
          </artifactSet>
        </configuration>
      </execution>
    </executions>
  </plugin>
</plugins>
