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:

正如在其他回答中所述,现在向Maven Central发出请求需要https,而旧版本的Maven使用http。
如果你不想/不能升级到Maven 3.2.3+,你可以通过添加以下代码到你的MAVEN_HOME\conf\settings.xml到<profiles>部分来解决:
<profile>
<id>maven-https</id>
<activation>
<activeByDefault>true</activeByDefault>
</activation>
<repositories>
<repository>
<id>central</id>
<url>https://repo1.maven.org/maven2</url>
<snapshots>
<enabled>false</enabled>
</snapshots>
</repository>
</repositories>
<pluginRepositories>
<pluginRepository>
<id>central</id>
<url>https://repo1.maven.org/maven2</url>
<snapshots>
<enabled>false</enabled>
</snapshots>
</pluginRepository>
</pluginRepositories>
</profile>
这将始终是一个活动设置,除非您在需要时在POM中禁用/覆盖它。
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>
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
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>
