【问题描述】：

我刚刚在我的 Eclipse IDE 中导入了一些 maven 项目。但是我在 Eclipse 项目中有这个错误：

Failure to transfer org.apache.maven.plugins:maven-resources-plugin:pom:2.6 from https://intra.telecom.fr/CITnet/nexus/content/groups/public/ was cached in the local repository, 
resolution will not be reattempted until the update interval of ecPublicRepository has elapsed or updates are forced. 
Original error: 
Could not transfer artifact org.apache.maven.plugins:maven-resources-plugin:pom:2.6 from/to ecPublicRepository
 (https://intra.telecom.fr/CITnet/nexus/content/groups/public/): 
Access denied to https://intra.telecom.fr/CITnet/nexus/content/groups/public/org/apache/maven/plugins/maven-resources-plugin/2.6/maven-resources-plugin-2.6.pom. 
Error code 401, Unauthorized    pom.xml

但我已经定义了对网站 intra.telecom.fr 的访问权限在文件 C:\développement\apache-maven-3.0.5\conf\settings.xml 中：

【问题讨论】：

你确定你可以在没有代理的情况下访问intra.telecom.fr吗？？
我建议在yourUserHomeDir/.m2 中创建一个settings.xml 文件并在其中添加所有特定设置，而不是修改Maven 附带的settings.xml。 Eclipse 可能正在使用不同的 Maven 安装。如果您将自定义设置在 yourUserHomeDir/.m2/settings.xml 中，Eclipse 和其他 Maven 安装可能都会找到它们。

【解决方案1】：

使用命令加密你的主密码并将其放入~/.m2/settings-security.xml

mvn --encrypt-master-password  <your_master_pass>

将加密的主密码放入~/.m2/settings-security.xml。例如，如果你得到字符串{p123=}，文件内容将是

<settingsSecurity>
  <master>{p123=}</master>
</settingsSecurity>

通过运行以下命令加密您的 Maven 存储库密码： mvn --encrypt-password <your_repo_pass> 并创建 ~/.m2/settings.xml，内容如下：

<?xml version="1.0" encoding="UTF-8"?>
<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0" 
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
          xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd">

        <password>{hashed-passwd}</password>
      </server>
   </servers>
</settings>
