可以从代理后面访问maven资源库,需要帮助

Question

我试图从代理后面访问maven存储库.我正确配置了settings.xml(我猜是这样......)

  <proxies>
    <proxy>
      <active>true</active>
      <protocol>http</protocol>
      <username>username</username>
      <password>password</password>  
      <host>12.34.56.78</host>
      <port>8080</port>
    </proxy>
  </proxies>

但我仍然得到一个错误消息,如...如果我没有配置用户ID /密码获取正确的错误消息,这是HTTP响应代码407- 说需要身份验证.但是,如果我配置正确/不正确的代理身份验证,它总是打印下面的错

Answer 1

如果以上不起作用

步骤#2:添加wagon-http-lightweight扩展

Wagon HTTP轻量级库允许我们在使用NTLM代理时克服Maven(3.0.4)中的身份验证限制.我们可以按照以下步骤将Wagon HTTP轻量级库添加为Maven扩展:

• wagon-http-lightweight-2.2.jar从这里下载.

• 复制wagon-http-lightweight-2.2.jar到%M2_HOME%/lib/ext文件夹.

用于测试解决方案的示例pom.xml

要测试我们的方法,首先使用以下pom.xml创建一个简单的Maven项目:

<!-- pom.xml -->
<project xmlns="http://maven.apache.org/POM/4.0.0" 
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
  <modelVersion>4.0.0</modelVersion>
  <groupId>com.thira.testmavenplugindl</groupId>
  <artifactId>test-maven-plugin-dl</artifactId>
  <version>0.0.1-SNAPSHOT</version>
  <name>Test Maven Plugin Download Issue</name>
  <description>Example pom file to test Maven dependency download with NTLM proxies</description>
</project>

运行Maven目标如下所述.这应该成功执行并下载所有Maven依赖项:

mvn clean install

检查本地存储库目录(在settings.xml文件中定义)以确保正确下载所有依赖项.

Answer 2

它是NTLM代理吗？如果是,尝试提供domainname\username的username(如在提出这个线程).

<username>DOMAINNAME\USERNAME</username>

Answer 3

另一种方法是在您的机器上获取Cntlm(http://cntlm.sourceforge.net/),使用您的域/密码/代理名称在cntlm.ini中配置您的NTLM代理.运行它:

cntlm.exe -v -a NTLMv2 -c cntlm.ini

编辑您的maven $ MAVEN_HOME\conf\settings.xml,并使用代理块:

<proxies>
   <proxy>
      <active>true</active>
      <protocol>http</protocol>
      <host>localhost</host>
      <port>3128</port>
      <nonProxyHosts>localhost|127.0.0.1</nonProxyHosts>
   </proxy>
</proxies>

现在使用-s选项运行maven :

mvn -s $MAVEN_HOME\conf\settings.xml <goal>
