java - 解决插件版本错误 'org.mortbay.jetty:jetty-maven-plugin'

Question

我正在使用 apache-maven-3.0.5 并且出现以下错误:

错误解决插件'org.mortbay.jetty:jetty-maven-plugin'的版本来自存储库 [本地 (C:\Documents and Settings\lamiranda.m2\repository)，vaadin 快照 ( http://oss.sonatype.org/content/repositories/vaadin-snapshots/ ),中央(http://repo.maven.apache.org/maven2)]:在任何插件存储库中找不到插件

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

你能帮帮我吗？

Answer 1

在您的 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>

备注:<project>标签就在那里代表 <repositories> 的相对位置

如果它正在访问的存储库中不存在该版本，请检查它尝试下载的版本，然后检查您的网络设置
