知道为什么不下载依赖插件？

Answer 1

Solution很简单。由于它是我想要提取的插件，我需要使用pluginRepositories代替repositories

  <pluginRepositories>
    <pluginRepository>
      <id>sonatype-nexus-snapshots</id>
      <name>Sonatype Nexus Snapshots</name>
      <url>https://oss.sonatype.org/content/repositories/snapshots</url>
      <releases>
        <enabled>false</enabled>
      </releases>
      <snapshots>
        <enabled>true</enabled>
      </snapshots>
    </pluginRepository>
  </pluginRepositories>

Answer 2

您可以看到maven正在错误的回购http://repository.apache.org/snapshots/中寻找快照您的工件位于https://oss.sonatype.org/content/repositories/snapshots

您用来运行的pom不是定义超类型<repository>的pom，或者它被覆盖。检查你运行maven的文件夹中的有效pom并找到定义，你可能会发现它是apache.org而不是sonatype的

或者，通常不建议在您的poms中使用<repository>，因为它会使无法访问特殊仓库的其他人无法使用工件，请检查this article。我更喜欢在 settings.xml

中配置自定义repo（sonatype snapshots）
