Java 执行 org.apache.maven.plugins：mavenjarplugin：3.2.0：jar 时缺少必需的类

当我在maven项目上运行mvn clean install时，它会给我以下错误

推荐答案

您可以运行带有参数-X的maven build命令来启用调试日志(log)记录.

通常，类MavenArchiveConfiguration是从maven-archiver加载的，这是maven-jar-plugin的依赖项.这些依赖项在插件的pom文件中进行管理，并由maven构建过程从该pom加载.

当我在本地修改这个插件的pom文件(全部删除dependencies个)时，我可以重现这个错误消息.这让我相信您下载的副本有问题.

作为一种解决方案，您可以删除.m2\repository\org\apache\maven\plugins\和.m2\repository\org\apache\maven\maven-archiver的内容，然后再次try 构建，然后应该从Maven Central再次下载所有正确的插件文件和依赖项.

然后，您应该在本地.m2文件夹中找到插件+依赖项的jar+pom文件:.m2\repository\org\apache\maven\plugins\maven-jar-plugin\3.2.0和.m2\repository\org\apache\maven\maven-archiver\3.5.0.您还可以在这些文件夹中查找_remote.repositories文件，以判断是否存在任何下载问题.

您还可以判断是否配置了可能会向您提供损坏的JAR/POM文件的自定义pluginRepositories.您可以通过运行mvn help:effective-pom来查看您的整个POM文件.

通常情况下，这应该包括super pom个中的以下内容:

  <pluginRepositories>
    <pluginRepository>
      <releases>
        <updatePolicy>never</updatePolicy>
      </releases>
      <snapshots>
        <enabled>false</enabled>
      </snapshots>
      <id>central</id>
      <name>Central Repository</name>
      <url>https://repo.maven.apache.org/maven2</url>
    </pluginRepository>
  </pluginRepositories>

更极端的措施可能是下载一个更新版本的maven，或者清除你的整个本地.m2(如果你有重要的文件，就创建一个备份).

这些将是解决这个问题的地方.
