POM更改为排除超过一个级别的依赖项与将一个级别排除在一个级别之外相同。

根据documentation 如果依赖图如下

Project-A
   -> Project-B
        -> Project-D 
              -> Project-E <!-- Exclude this dependency -->
              -> Project-F
   -> Project C

在项目A POM中排除项目E 

<project>
  <modelVersion>4.0.0</modelVersion>
  <groupId>sample.ProjectA</groupId>
  <artifactId>Project-A</artifactId>
  <version>1.0-SNAPSHOT</version>
  <packaging>jar</packaging>
  ...
  <dependencies>
    <dependency>
      <groupId>sample.ProjectB</groupId>
      <artifactId>Project-B</artifactId>
      <version>1.0-SNAPSHOT</version>
      <exclusions>
        <exclusion>
          <groupId>sample.ProjectE</groupId> <!-- Exclude Project-E from Project-B -->
          <artifactId>Project-E</artifactId>
        </exclusion>
      </exclusions>
    </dependency>
  </dependencies>
</project>

Maven depdendcy plugin输出格式为：

[groupId]:[artifactId]:[type]:[version]

表示依赖：

org.eclipse.persistence:javax.persistence:jar:2.1.0:compile

该组为org.eclipse.persistence，artifactId为javax.persistence

您的排除规则是错误的，组和工件是相反的。它应该是：

<exclusions>
    <exclusion>
        <artifactId>javax.persistence</artifactId>
        <groupId>org.eclipse.persistence</groupId>
    </exclusion>
</exclusions>

编辑：添加maven-shade-plugin配置

要从maven-shade-plugin中排除相关性，请尝试将exclusions添加到插件配置中：

<execution>
    <phase>package</phase>
    <goals>
        <goal>shade</goal>
    </goals>
    <configuration>
        <artifactSet>
            <excludes>
                <exclude>org.eclipse.persistence:javax.persistence</exclude>
            </excludes>
        </artifactSet>
        <transformers>
            <transformer implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
                <mainClass>hello.HelloWorld</mainClass>
            </transformer>
        </transformers>
    </configuration>
</execution>
