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:

我也面临着同样的问题。我尝试了两种解决方案，对我来说都很有效。
更新Maven版本存储库(Maven版本>= 3.2.3)
限制当前Maven版本使用HTTPS链接。
更新Maven版本存储库:
下载包含默认https地址的Apache Maven二进制文件(Apache Maven 3.6.3二进制文件)。在NetBeans菜单栏的工具(Java Maven对话框视图)中打开选项对话框窗口。并在Maven Home List Box (Maven Home List Box View)中选择browse选项。添加新下载的Apache Maven版本(Updated Maven Home List Box View)后，项目构建并成功运行。
限制当前Maven版本使用HTTPS链接:
在项目的pom.xml中包含以下代码。
<project>
...
<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>
</project>
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。
下面的链接让我摆脱了麻烦，
https://support.sonatype.com/hc/en-us/articles/360041287334-Central-501-HTTPS-Required
您可以在maven、apache-maven/conf/settings.xml中进行更改。
或者，如果在pom.xml中指定，则在那里进行更改。
之前,
<repository>
<id>maven_central_repo</id>
<url>http://repo.maven.apache.org/maven2</url>
</repository>
Now,
<repository>
<id>maven_central_repo</id>
<url>https://repo.maven.apache.org/maven2</url>
</repository>
注意从http到https的变化
