shade打包jar报错

Question

shade打包报错：Cannot find 'manifestEntries' in class org.apache.maven.plugins.shade.resource.AppendingTransformer

Cannot find 'manifestEntries' in class org.apache.maven.plugins.shade.resource.AppendingTransformer

为什么会出现这个报错，应该怎么调整代码或者是项目设置

pom,xml

打包过程中报错

已尝试

1.更换maven、shade、springboot版本
2.添加AppendingTransformer无效

根据您提供的信息，看起来在执行Maven的maven-shade-plugin时遇到了错误，错误消息提到找不到manifestEntries。这通常是因为插件版本与使用的Java或Spring Boot版本不兼容，或者配置文件有误。

为了解决这个问题，您可以按照以下步骤操作：

1. 确保您的Maven、shade plugin以及Spring Boot的版本是兼容的。对于较新的Spring Boot版本（例如2.x以上），推荐使用较新版本的maven-shade-plugin，比如3.2.4。检查其他依赖项是否也需要更新。

2. 检查pom.xml中的 <transformers> 部分，确保使用的是正确的ManifestResourceTransformer类路径。从错误消息来看，似乎插件没有找到manifestEntries属性，这可能是因为类路径写错了。确认一下是否有拼写错误或遗漏。

3. 如果问题依然存在，尝试移除所有无关的排除过滤器（<excludes>）并重新构建，看看是否可以解决。有时候过多的排除可能会导致一些意外的问题。

基于上述建议，您可以尝试修改您的pom.xml如下：

<project>
...
  <build>
    ...
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-shade-plugin</artifactId>
        <version>3.2.4</version>
        <configuration>
          <filters>
            <!-- 如果确实需要这些排除，再将它们添加回来 -->
            <!--
              <filter>
                <artifact>*:*</artifact>
                <excludes>
                  <exclude>META-INF/*.SF</exclude>
                  <exclude>META-INF/*.DSA</exclude>
                  <exclude>META-INF/*.RSA</exclude>
                </excludes>
              </filter>
            -->
          </filters>
          <minimizeJar>true</minimizeJar>
          <transformers>
            <transformer
                implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
              <mainClass>com.example.Application</mainClass>
            </transformer>
          </transformers>
        </configuration>
        <executions>
          <execution>
            <id>shade-my-jar</id>
            <phase>package</phase>
            <goals>
              <goal>shade</goal>
            </goals>
          </execution>
        </executions>
      </plugin>
    </plugins>
    ...
  </build>
...
</project>

请注意，这里我将manifestEntries标签替换为了mainClass标签，这是因为它是一个更标准的属性名，用于指定主类。如果您确定需要排除某些资源，请将排除过滤器部分恢复原样。

然后，在命令行中运行以下命令来清理并重新构建项目：

mvn clean install

如果问题仍然存在，那么可能是项目结构或者依赖配置有问题。在这种情况下，提供项目的更多上下文信息（例如父级POM、依赖关系等）可能会有助于进一步分析和解决问题。
