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:

我也犯过这个错误。我照上面默罕默德说的做了。但是，它只解决了spring-boot-dependencies的错误，并且spring-boot-dependencies有子依赖项。有21个错误。之前是2个错误。是这样的:
Non-resolvable import POM: Could not transfer artifact org.springframework.cloud:spring-cloud-dependencies:pom:Hoxton.SR3 from/to central
错误消息中还要求使用HTTPS。
我将maven版本从3.2.2更新到3.6.3，将java版本从8更新到11。现在，https要求的所有错误都消失了。
更新maven版本
从这里下载最新的maven: Download maven
解压缩并将其移动到/opt/maven/
设置路径export path =$ path:/opt/maven/bin
并且，还从PATH中删除旧的maven
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" }
}
最初来自https://stackoverflow.com/a/59796324/32453，虽然这可能有用:
注意，你的父pom也可以(重新)定义存储库，如果它因为某种原因覆盖了central并指定了http，你就需要修复它(修复的地方:~/.m2/settings.xml)
还有父母。
如果你不能在父pom中修复它，你可以覆盖父pom的repo，就像这样，在你的子pom中(从3.6.3默认的超级pom中提取，似乎他们也从repo1中更改了名称):
<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 true if desired, default is false -->
</snapshots>
</repository>
</repositories>
