Maven Shade插件:如何解决警告消息“定义1个重叠资源:[WARNING]-META-INF / MANIFEST.MF”

问题描述

对于

  <dependencies>
    ...
    <dependency>
        <groupId>com.manuel.jordan</groupId>
        <artifactId>some module</artifactId>
        <version>0.0.1-SNAPSHOT</version>
    </dependency>
    ... 
  </dependencies>

  <build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-shade-plugin</artifactId>
            <version>3.2.4</version>
            <executions>
                <execution>
                    <id>create-fat-jar</id>
                    <phase>package</phase>
                    <goals>
                        <goal>shade</goal>
                    </goals>
                    <configuration>
                        <finalName>somename</finalName>
                    </configuration>
                </execution>
            </executions>
        </plugin>
    </plugins>
  </build>

插件运行良好,但始终显示以下消息:

[WARNING] moduleA-0.0.1-SNAPSHOT.jar,moduleB-0.0.1-SNAPSHOT.jar,.... more
          moduleN-0.0.1-SNAPSHOT.jar define 1 overlapping resource: 
[WARNING]   - meta-inf/MANIFEST.MF
[WARNING] maven-shade-plugin has detected that some class files are
[WARNING] present in two or more JARs. When this happens,only one
[WARNING] single version of the class is copied to the uber jar.
[WARNING] Usually this is not harmful and you can skip these warnings,[WARNING] otherwise try to manually exclude artifacts based on
[WARNING] mvn dependency:tree -Ddetail=true and the above output.
[WARNING] See http://maven.apache.org/plugins/maven-shade-plugin/

如何删除警告消息?,主要是因为我所有的模块在其Meta/MANIFEST.MF目录中都没有src/main/resources文件

解决方法

在配置中添加此选项将从构建中排除资源文件

<filters>
   <filter>
      <artifact>org.example:*</artifact>
      <excludes>
         <exclude>META-INF/*.MF</exclude>
      </excludes>
   </filter>
</filters>
