Question

我正在使用apache-maven-3.0.5并且我收到以下错误：

解析插件版本'org.mortbay.jetty：jetty-maven-plugin'时出错从存储库[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）]：在任何插件库中找不到插件

当我执行“Run As Maven clean”或“Run As Maven install”时，会出现以下错误：

你能帮助我吗？

Answer 1

在pom.xml中添加以下代码段

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

注意：<project>标记用于表示<repositories>

的相对位置

检查它试图下载的版本，如果它正在敲定的存储库中不存在，那么请检查您的网络设置

Answer 2

看起来网络连接失败。插件网址：http://repo.maven.apache.org/maven2/org/eclipse/jetty/jetty-maven-plugin/ 是可用的。检查您在构建时是否在线，或configure your proxy如果有的话。
