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?
[ERROR] Unresolveable build extension:

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。
如果您使用的是旧版本的Netbeans，则必须在maven中进行更改才能在http上使用https
打开C:\Program Files\ NetBeans8.0.2\java\maven\conf\settings.xml
并将下面的代码粘贴在镜像标签之间
<mirror>
<id>maven-mirror</id>
<name>Maven Mirror</name>
<url>https://repo.maven.apache.org/maven2</url>
<mirrorOf>central</mirrorOf>
</mirror>
它将强制maven使用https://repo.maven.apache.org/maven2 url。
分享这些，以防有人需要:
旧的Gradle配置(没有Gitlab, Docker部署，用于简单项目)
repositories {
google()
jcenter()
maven { url "http://dl.bintray.com/davideas/maven" }
maven { url 'https://plugins.gradle.org/m2/' }
maven { url 'http://repo1.maven.org/maven2' }
maven { url 'http://jcenter.bintray.com' }
}
新配置:
repositories {
google()
jcenter()
maven { url "https://dl.bintray.com/davideas/maven" }
maven { url 'https://plugins.gradle.org/m2/' }
maven { url 'https://repo1.maven.org/maven2' }
maven { url 'https://jcenter.bintray.com' }
}
注意https。快乐编码:)
Maven正在转向HTTPS并禁用HTTP访问
简而言之，从2020年1月15日起，Maven中央存储库不再支持HTTP连接(其他存储库也在这么做)。因此，您将指示您的Maven/Gradle设置使用HTTPS URL。
解决方案:
您可以从以下三种方法中选择一种。
Add a repository in your project´s pom.xml file
<project>
...
<repositories>
<repository>
<id>central maven repo</id>
<name>central maven repo https</name>
<url>https://repo.maven.apache.org/maven2</url>
</repository>
</repositories>
</project>
Add the repository into a profile in the settings.xml file.
<profile>
<id>my profile</id>
<repositories>
<repository>
<id>central maven repo</id>
<name>central maven repo https</name>
<url>https://repo.maven.apache.org/maven2</url>
</repository>
</repositories>
</profile>
Update you maven version to a new one that uses https values as default. The lastest one at this moment 3.6.3 Download here
Gradle:
只替换HTTPS版本的URL。
repositories {
maven { url "https://repo.maven.apache.org/maven2" }
}
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>
