java - Maven 想要访问 central.maven.org

问题描述

几天以来，我在 gitlab (maven:3.6.3-jdk-11) 上构建的 maven 尝试访问 central.maven.org 并失败

Caused by: org.eclipse.aether.transfer.ArtifactTransferException: Could not transfer artifact javax.media:jai_core:jar:1.1.3 from/to central.maven.org (http://central.maven.org/maven2): Transfer failed for http://central.maven.org/maven2/javax/media/jai_core/1.1.3/jai_core-1.1.3.jar
...
Caused by: java.net.UnknownHostException: central.maven.org: Name or service not known

我没有更改settings.xml。它看起来像这样：

...
<repositories>
    <repository>
          <id>central</id>
          <name>Central Repository</name>
          <url>https://repo1.maven.org/maven2/</url>
          <layout>default</layout>
          <snapshots>
            <enabled>false</enabled>
          </snapshots>
          <releases>
            <enabled>false</enabled>
            <updatePolicy>never</updatePolicy>
          </releases>
        </repository>
    </repositories>

<pluginRepositories>
    <pluginRepository>
      <id>central</id>
      <name>Central Repository</name>
      <url>https://repo1.maven.org/maven2/</url>
      <layout>default</layout>
      <snapshots>
        <enabled>false</enabled>
      </snapshots>
      <releases>
        <updatePolicy>never</updatePolicy>
      </releases>
    </pluginRepository>
</pluginRepositories>

...

也就是说，我没有为central.maven.org 配置查找。根据https://maven.apache.org/ref/3.6.3/maven-model-builder/super-pom.html，即使是maven super pom也不包含这个url

这是从哪里来的，我该如何解决？
