我怀疑我有Maven代理问题.当我创建一个新项目时：
1)文件 – >新 – > Maven项目
2)我选择原型：in org.apache.maven.archetypes – > Maven的原型 – web应用
3)我得到这个错误：
Could not resolve archetype org.apache.maven.archetypes:maven-archetype-webapp:RELEASE from any of the configured repositories.
Creating maven-archetype-webapp’ has encountered a problem. Could not resolve archetype org.apache.maven.archetypes:maven-archetype-webap p:RELEASE from any of the configured repositories.
细节 ：

我们可以看到问题的根源：连接被拒绝：连接
我已经这样做了：
1)窗口 – >偏好 – >一般 – >网络连接.我在我的代理的url和端口输入了Manual for HTTP protocol.
它的工作原理是因为在此之前,Spring Tool Suite不想更新.之后,没关系.
