我在 SpringSource Tool Suite 中创建了一个新的 Maven 项目。我在我的新 Maven 项目中收到此错误。

请注意,我能够构建它。错误显示在 IDE 内的 pom.xml 中。有什么解决方案吗?
通过使用以下内容来简化事情settings.xml
:
<?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">
<proxies>
<proxy>
<id>myproxy</id>
<active>true</active>
<protocol>http</protocol>
<username>user</username> <!-- Put your username here -->
<password>pass</password> <!-- Put your password here -->
<host>123.45.6.78</host> <!-- Put the IP address of your proxy server here -->
<port>80</port> <!-- Put your proxy server's port number here -->
<nonProxyHosts>local.net|some.host.com</nonProxyHosts> <!-- Do not use this setting unless you know what you're doing. -->
</proxy>
</proxies>
</settings>
在Linux/Unix下,将其放在~/.m2/settings.xml
。在 Windows 下将其放在c:\documents and settings\youruser\.m2\settings.xml
or c:\users\youruser\.m2\settings.xml
.
你不需要<mirrors/>
, <profiles/>
and <settings/>
部分,除非你真的知道它们的用途。
