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?

当前回答

自2020年1月15日起,中央存储库不再支持 在纯HTTP上的不安全通信,并要求所有请求 通过HTTPS加密到存储库。 如果收到此错误,则需要替换所有URL 对Maven Central的引用及其规范的HTTPS对等物。

我们在我的项目build.gradle中做了以下更改:

Old:

repositories {
   maven { url "http://repo.maven.apache.org/maven2" }
}

New:

repositories {
   maven { url "https://repo.maven.apache.org/maven2" }
}

其他回答

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

对我来说(公司编码器)还在settings.xml中添加了一个镜像存储库修复了这个问题。我还在docker容器中使用Maven。

<mirrors>
    <mirror>
        <id>https-mirror</id>
        <name>Https Mirror Repository</name>
        <url>https://repo1.maven.org/maven2</url>
        <mirrorOf>central</mirrorOf>
    </mirror>
</mirrors>

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

同样的问题也发生在jcenter上。

自2020年1月13日起,Jcenter仅支持HTTPS协议。

使用相同方法获得依赖项的项目将开始面临问题。为了快速修复,请在build.gradle中执行以下操作

而不是

repositories {
jcenter ()
//others
}

用这个:

repositories {
jcenter { url "http://jcenter.bintray.com/"}
//others
}

我在Docker容器上使用干净的Maven/Java安装。

对我来说,我必须cd $M2_HOME/conf并编辑settings.xml文件。在<mirrors>…</mirrors>中添加以下块

<mirror>
  <id>central-secure</id>
  <url>https://repo.maven.apache.org/maven2</url>
  <mirrorOf>central</mirrorOf>
</mirror>
