对 http://repo1.maven.org/maven2/ 的请求返回 501 HTTPS 必需状态和正文

Question

截至 2020 年 1 月 15 日，我在向中央存储库提出请求时收到以下回复：

Requests to http://repo1.maven.org/maven2/ return a 501 HTTPS Required status and a body:

501 HTTPS Required. 
Use https://repo1.maven.org/maven2/
More information at https://links.sonatype.com/central/501-https-required
Requests to http://repo.maven.apache.org/maven2/ return a 501 HTTPS Required status and a body:

501 HTTPS Required. 
Use https://repo.maven.apache.org/maven2/
More information at https://links.sonatype.com/central/501-https-required

如何满足此要求以便我可以重新访问 Central？

我在控制台中收到此错误

Answer 1

自 2020 年 1 月 15 日起，中央存储库不再支持通过普通 HTTP 进行的不安全通信，并要求对存储库的所有请求都通过 HTTPS 进行加密。

如果您收到此错误，则需要将所有对 Maven Central 的 URL 引用替换为其规范的 HTTPS 对应项：

将http://repo1.maven.org/maven2/替换为https://repo1.maven.org/maven2/

将http://repo.maven.apache.org/maven2/替换为https://repo.maven.apache.org/maven2/

如果由于任何原因您的环境不支持 HTTPS，您可以选择在http://insecure.repo1.maven.org/maven2/上使用我们专用的不安全端点

有关转向 HTTPS 的更多背景信息，请参阅https://blog.sonatype.com/central-repository-moving-to-https。

Answer 2

我修复了以下步骤，但它使用 http：1) 到 .m2 文件夹 2) 创建文件 settings.xml 3) 在下面复制粘贴

<settings>
    <mirrors>
        <mirror>
          <id>centralhttps</id>
          <mirrorOf>central</mirrorOf>
          <name>Maven central https</name>
          <url>http://insecure.repo1.maven.org/maven2/</url>
        </mirror>
      </mirrors>
      </settings>

Answer 3

请注意，您的父 pom 也可以（重新）定义存储库，并且如果它出于某种原因覆盖了中央和指定的 http，则您需要修复它（因此需要修复：~/.m2/settings.xml 以及父poms）。

如果您无法在父 pom 中修复它，您可以覆盖父 pom 的 repo，就像这样，在您的子 pom 中（从 3.6.3 默认超级 pom 中提取，似乎他们也从 repo1 更改了名称）：

  <repositories>
    <repository>
      <id>central</id>
      <name>Central Repository</name>
      <url>https://repo.maven.apache.org/maven2</url> <!-- the https you've been looking for -->
      <layout>default</layout>
      <snapshots>
        <enabled>false</enabled> <!-- or set to false if desired, default is true /sf/answers/4317917761/ -->
      </snapshots>
    </repository>
  </repositories>

Answer 4

尝试在 pom.xml 中添加下一个 statament

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

<repositories>
 <repository>
   <id>central</id>
   <name>Central Repository</name>
   <url>https://repo.maven.apache.org/maven2</url>
   <layout>default</layout>
   <snapshots>
      <enabled>false</enabled>
   </snapshots>
 </repository>
</repositories>

此外，您必须在以下位置指定存储库：MAVEN\conf\settings.xml

<mirrors>
 <mirror>
   <id>other-mirror</id>
   <mirrorOf>central</mirrorOf>
   <name>Other Mirror Repository</name>
   <url>http://insecure.repo1.maven.org/maven2/</url>
 </mirror>
 <mirror>
  <id>internal-repository</id>
  <name>Maven Repository Manager running on https://repo1.maven.org/maven2</name>
  <url>https://repo1.maven.org/maven2</url>
  <mirrorOf>*</mirrorOf>
 </mirror>
</mirrors>

Answer 5

仅供 Gradle 用户使用，

repositories {
   maven {
      url = 'https://repo.maven.apache.org/maven2'
   }
}
