Intellij 无法连接到本地 m2 存储库
Intellij can't connect to local m2 repository
总结
我已经看到一些问题 [1] [2] [3] 与此有点相似，但 none 的答案已经产生了任何形式的成功。
所以，这是我遇到的问题：
1) pom 表明它无法连接到本地 .m2 存储库。
2) Intellij 中的 Maven 设置显示拒绝连接到本地 .m2 存储库的错误。
到目前为止我尝试过的：
链接问题中的几乎所有内容。其中：
1) Delete the entire .m2/repository 手动文件夹，然后再次更新您的 Maven 项目。
2) Invalidate your Idea cache and restart Idea.
3) increasing Maven's allocated memory
4) Setting localhost to only 127.0.0.1
5) Adding -Djava.net.preferIPv4Stack=true flag
6) Starting Intellij with Java 1.7 instead of 1.8
7) 卸载并重新安装 Maven、Java 和 Intellij

更新
您正在使用哪个 settings.xml？
/Users/donato/.m2/settings.xml
您在 IntelliJ 中打开的任何 Maven 项目都会发生这种情况，还是只有这个？
所有 Maven 项目都会出现这种情况
此外，除了 Intellij 显示索引失败之外，如果从 Maven 面板调用，您的构建是否有效？
构建失败，提示很多符号找不到。
我有两个建议：
如果有代理，在setting.xml中添加其配置参数
您必须指定：
<proxy>
<active></active>
<protocol></protocol>
<host></host>
<port></port>
<username></username>
<password></password>
</proxy>
Copy/Paste 127.0.0.1 localhost 在你的主机文件
终于找到问题了。我的 /etc/hosts 文件中有一个无效字符，它阻止了与本地主机的任何连接。这是我输入以下命令时发现的：
$ file -b /etc/hosts
UTF-8 Unicode text
我在 etc 主机中手动输入了正确的值，现在一切正常。
总结

更新
您正在使用哪个 settings.xml？
/Users/donato/.m2/settings.xml
您在 IntelliJ 中打开的任何 Maven 项目都会发生这种情况，还是只有这个？
所有 Maven 项目都会出现这种情况
此外，除了 Intellij 显示索引失败之外，如果从 Maven 面板调用，您的构建是否有效？
构建失败，提示很多符号找不到。
我有两个建议：
如果有代理，在setting.xml中添加其配置参数 您必须指定：
<proxy> <active></active> <protocol></protocol> <host></host> <port></port> <username></username> <password></password> </proxy>Copy/Paste 127.0.0.1 localhost 在你的主机文件
终于找到问题了。我的 /etc/hosts 文件中有一个无效字符，它阻止了与本地主机的任何连接。这是我输入以下命令时发现的：
$ file -b /etc/hosts
UTF-8 Unicode text
我在 etc 主机中手动输入了正确的值，现在一切正常。
