Maven无法连接到存储库(我认为) [英] Maven fails to connect to repositories (I think)

问题描述

1. 我开始此教程，适用于win 8.1.
2. 我下载了JDK8和Maven.

3. 我设置了Maven(将mvn添加到PATH，设置JAVA_HOME).

1. I started doing this tutorial, on win 8.1.
2. I downloaded JDK8 and Maven.

3. I set up Maven (added mvn to PATH, set JAVA_HOME).

• mvn --version的输出:

Apache Maven 3.3.9 (bb52d8502b132ec0a5a3f4c09453c07478323dc5; 2015-11-10T18:41:47+02:00) Maven home: C:\apache\apache-maven-3.3.9\bin\..

为项目创建的文件夹.

试图运行此命令(从教程中复制粘贴，忽略SO中的换行符):mvn archetype:generate -DarchetypeArtifactId=maven-archetype-webapp -DarchetypeGroupId=org.apache.maven.archetypes -DinteractiveMode=false -DgroupId=com.example.employees -DartifactId=employees-app -DarchetypeVersion=1.0

tried to run this command (copy-paste from the tutorial, ignore the line breaks in SO): mvn archetype:generate -DarchetypeArtifactId=maven-archetype-webapp -DarchetypeGroupId=org.apache.maven.archetypes -DinteractiveMode=false -DgroupId=com.example.employees -DartifactId=employees-app -DarchetypeVersion=1.0

• 命令输出: pastebin
• 输出摘要:No plugin found for prefix 'archetype' in the current project and in the plugin groups [org.apache.maven.plugins, org.codehaus.mojo] available from the repositories [local (C:\Users\yogevl\.m2\repository), central (https://repo.maven.apache.org/maven2)] -> [Help 1]

• output from command: pastebin
• summary of the output: No plugin found for prefix 'archetype' in the current project and in the plugin groups [org.apache.maven.plugins, org.codehaus.mojo] available from the repositories [local (C:\Users\yogevl\.m2\repository), central (https://repo.maven.apache.org/maven2)] -> [Help 1]

SO中的答案假设我有一个代理.我没有，我在此处进行了检查.另外，我可以使用Chrome访问 repo . 另一个答案建议以管理员身份运行cmd.我做到了-同样的结果.

Answers in SO assumes I have a proxy. I don't, I checked it here. Plus, I am able to get to the repo using Chrome. Another answer advised to run the cmd as an Administrator. I did - same result.

在输出末尾，我还遵循了链接:

I also followed the link at the end of the output:

1. 不这么认为，因为我是从托词复制粘贴的.
2. 同上.
3. 同上.
4. 不确定这一点-settings.xml是默认文件.我需要更改吗?
5. 与1-3相同.

谢谢您的帮助！

推荐答案

在此处阅读注释后，解决方案是更新cacerts文件，因为该文件缺少Maven存储库的正确证书(感谢I-LOVE-2-REVIVE (提供答案和链接).

After reading the comments here, the solution was to update the cacerts file, since it was lacking the proper certificate for the Maven repo (thanks I-LOVE-2-REVIVE for the answer and the link).

因此，如果您遇到与我相同的问题，请注意以下几点:

So, if you have the same problem I had, here some things:

1. 此文章将指导您如何将证书添加到cacerts文件(再次，感谢I-LOVE-2-REVIVE的链接).确保为所需的存储库添加证书.
2. 请记住，每个jdk/jde管理一个不同的证书列表.
3. keytool位于%JAVA_HOME%\bin(起初我以为是linux shell工具，不是).

1. This article will guide you how to add the certificate to the cacerts file (Again, thanks I-LOVE-2-REVIVE for the link). Make sure you add the certificate for the repo you need.
2. Remember that each jdk/jde manages a different certificate list.
3. The keytool is located at %JAVA_HOME%\bin (at first I thought it was a linux shell tool, it's not).
