解决错误版本的插件“org.mortbay.jetty：码头 - Maven的插件”

Question

我使用的Apache Maven的-3.0.5，我得到以下错误：

解决错误版本的插件'org.mortbay.jetty：jetty-maven-plugin' from the repositories [local（C：\ Documents and Settings \ lamiranda.m2 \ repository）， vaadin-snapshots（http://oss.sonatype.org/content/repositories/vaadin-snapshots/）， central（http：// repo .maven.apache.org/maven2）]：插件没有在任何插件库中找到

当我做“运行为Maven干净”或“作为Maven安装运行”时出现以下错误：

你能帮助我吗？按照你的pom.xml片段

Answer 1

附加

<project ...> 
<repositories> 
    <repository> 
     <id>maven repo</id> 
     <url>http://repo1.maven.org/maven2/</url> 
    </repository> 
</repositories> 
</project> 

注：<project>标签只是为了表示<repositories>

检查它正在尝试，如果它不存在，下载的版本的相对位置然后检查您的网络设置

Answer 2

看起来像是网络连接失败。 插件网址：http://repo.maven.apache.org/maven2/org/eclipse/jetty/jetty-maven-plugin/ 可用。 检查你在编译或configure your proxy（如果有的话）。
