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.
无法转移org.apache.maven.plugins:来自http://repo1.maven.org/maven2的 maven-surefire-plugin:pom:2.7.1 被缓存在本地存储库中,在更新间隔之前不会重新尝试解析中心已经过去或强制更新.原始错误:无法传输工件org.apache.maven.plugins:maven-surefire-plugin:pom:2.7.1 from/to central(http://repo1.maven.org/maven2):连接超时

使用以下内容简化事物settings.xml:

在Linux/Unix下,将其放在下面~/.m2/settings.xml.在Windows下将其置于c:\documents and settings\youruser\.m2\settings.xml或c:\users\youruser\.m2\settings.xml.
你不需要的<mirrors/>,<profiles/>并且<settings/>部分,除非你真的知道自己在做什么的.

当我更新maven并在Eclipse中选中" 强制更新快照/版本 " 选项时,我就可以解决这个问题.这清除了所有错误.所以右键单击项目 - > Maven - > 更新项目,然后检查上面的选项 - > 确定.希望这对你有所帮助.

看来您的Maven无法连接到http://repo1.maven.org/maven2上的Maven存储库.
如果您使用代理并且可以使用浏览器访问该链接,则需要将相同的设置应用于Spring Source Tool Suite(如果您在套件中运行)或Maven.
对于Maven代理设置settings.xml,在.m2目录中创建一个包含以下详细信息
<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

<proxies>
<proxy>
<active>true</active>
<protocol>http</protocol>
<host>PROXY</host>
<port>3120</port>
<nonProxyHosts>maven</nonProxyHosts>
</proxy>
</proxies>
</settings>

如果您不使用代理并且可以使用浏览器访问该链接,请删除上述任何代理设置.
对我有帮助的是@carlspring的建议(创建一个settings.xml来配置你的http代理):
<?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>

然后按照@Peter T的建议刷新eclipse项目maven:
Eclipse 中的“强制更新快照/版本”。这会清除所有错误。因此右键单击项目 -> Maven -> 更新项目,然后选中上面的选项 -> 确定。希望这对您有帮助。
看来我是网络问题。在你这边,或者在 Maven 这边,或者中间的任何地方。请稍后再试。
如果错误是永久性的,请检查您的网络设置。如果您使用代理,则需要在 ~/.m2/settings.xml 中包含以下内容:
<proxies>
<proxy>
<id>optional</id>
<active>true</active>
<protocol>http</protocol>
<username>proxyuser</username>
<password>proxypass</password>
<host>proxy.host.net</host>
<port>80</port>
<nonProxyHosts>local.net|some.host.com</nonProxyHosts>
</proxy>
</proxies>
