无法将工件org.apache.maven.plugins:maven-surefire- plugin:pom:2.7.1从中央传输到中央(http://repo1.maven.org/maven2)
我在SpringSource Tool Suite中创建了一个新的maven项目。我在新的Maven项目中遇到此错误。
无法从http://repo1.maven.org/maven2传输org.apache.maven.plugins:maven-
surefire-plugin:pom:2.7.1
缓存在本地存储库中,直到更新间隔才会重新尝试解析已用完或已强制更新。原始错误:无法从/到中央(http://repo1.maven.org/maven2)传输工件org.apache.maven.plugins:maven-
surefire-plugin:pom:2.7.1 :连接超时

请注意,我能够构建它.IDE内的pom.xml中显示错误。任何解决方案?

通过使用以下内容简化操作
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,将其放在下
~/.m2/settings.xml
。在Windows下,将其放在c:\documents and settings\youruser\.m2\settings.xml
或下c:\users\youruser\.m2\settings.xml
。除非您真的知道它们的用途,否则不需要
<mirrors/>
,<profiles/>
和<settings/>
部分。
