最近，在Jenkins中运行的Maven构建作业失败，出现以下异常，表示它们无法从Maven Central提取依赖项，应该使用HTTPS。我不知道如何将请求从HTTP更改为HTTPS。有人能指导我一下这件事吗?

我也有同样的问题，但我用的是GitLab而不是Jenkins。我必须采取的步骤来克服这个问题:
My project is in GitLab so it uses the .yml file which points to a Docker image I have to do continuous integration, and the image it uses has the http://maven URLs. So I changed that to https://maven.
That same Dockerfile image had an older version of Maven 3.0.1 that gave me issues just overnight. I updated the Dockerfile to get the latest version 3.6.3
I then deployed that image to my online repository, and updated my Maven project ymlfile to use that new image.
And lastly, I updated my main projects POM file to reference https://maven... instead of http://maven
我意识到这更适合我的设置。但是如果不执行上述所有步骤，我仍然会继续得到这个错误消息
返回代码是:501,ReasonPhrase:HTTPS Required
错误:
传输文件失败:http://repo.maven.apache.org/maven2/org/apache/maven/wagon/wagon-ssh/2.1/wagon-ssh-2.1.pom。
返回代码是:501,ReasonPhrase:HTTPS Required。
根本原因分析:
Maven中心期望客户端使用https，但客户端只发出普通的HTTP请求。
因此，请求下载名为“wagon-ssh-2.1”的软件包。Pom’失败了。
如何解决这个问题?
替换URL“http://repo.maven.apache.org/maven2”
与“https://repo.maven.apache.org/maven2”
在pom.xml文件或构建。项目的Gradle文件。
对于所有的公司程序员来说，理想情况下，
如果您得到这个错误，这意味着您的代码库仍然是由开源社区构建的。您需要使用内部公司的Maven存储库管理器来超越“中央”存储库。
您可以转到settings.xml并将中央存储库URL从http://重写为https://
<M2_HOME>/conf/settings.xml
找到镜像部分并添加以下条目:
<mirror>
<id>other-mirror</id>
<name>Other Mirror Repository</name>
<url>https://other-mirror.repo.other-company.com/maven2</url>
<mirrorOf>central</mirrorOf>
</mirror>
在URL部分，如果您使用http://repo1.maven.org/maven2/或http://repo.maven.apache.org/maven2/那么
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/
理想情况下，您需要在这里使用您公司的源代码控制管理/存储库URL。因为这将阻止与开源Maven存储库社区的任何联系。
正如在其他回答中提到的，从2020年1月15日起，中央Maven存储库不支持纯HTTP上的不安全通信。
尝试在任何浏览器中点击下面的URL。它会返回501
http://repo.maven.apache.org/maven2/org/apache/maven/wagon/wagon-ssh/2.1/wagon-ssh-2.1.pom
请尝试https。它会下载一个pom.xml文件:
https://repo.maven.apache.org/maven2/org/apache/maven/wagon/wagon-ssh/2.1/wagon-ssh-2.1.pom
请在settings .xml文件中添加它(https://repo.maven.apache.org/maven2):
<repositories>
<repository>
<id>Central Maven repository</id>
<name>Central Maven repository https</name>
<url>https://repo.maven.apache.org/maven2</url>
</repository>
</repositories>
