我试图构建Maven示例Spring Boot项目。我从https://start.spring.io/生成了Spring Boot项目。我做了Maven更新。当我使用pom.xml命令在Spring Tool Suite IDE中运行mvn clean install时，出现以下错误。

我能够使用您的pom.xml构建项目，请尝试使用此配置：
<settings>
...
<profiles>
<profile>
<id>central</id>
<repositories>
<repository>
<id>central</id>
<name>central</name>
<url> http://central.maven.org/maven2/</url>
<layout>default</layout>
<snapshotPolicy>always</snapshotPolicy>
</repository>
</repositories>
</profile>
</profiles>
<activeProfiles>
<activeProfile>central</activeProfile>
</activeProfiles>
...
</settings>
也如@BreakingBenjamin所指出的那样，用您的代理配置补充设置：
<proxies>
<proxy>
<active>true</active>
<protocol>http</protocol>
<host>mywonderfulproxy.com</host>
<port>8080</port>
</proxy>
</proxies>
如果您已经这样做了，请用更新的settings.xml
答案 1 :(得分：0)
通过在settings.xml中添加以下代理，我能够成功构建应用程序
<proxies>
<proxy>
<id>example-proxy</id>
<active>true</active>
<protocol>http</protocol>
<host>proxy.example.com</host>
<port>8080</port>
<username>proxyuser</username>
<password>somepassword</password>
<nonProxyHosts>www.google.com|*.example.com</nonProxyHosts>
</proxy>
</proxies>
