Eclipse 严重：向类org.jboss.resteasy.plugins.server.servlet.ResteasyBootstrap的侦听器实例发送上下文破坏事件时发生异常

我正试图为家庭作业配置开发环境。我已经安装了ApacheMaven、ApacheTomcat和EclipseJuno（JavaEE）以及所需的插件。我遵循了项目代码提供的wiki。源通过SVN导入。我已经安装了所有缺少的库，并设置了类路径。但是，当我选择在服务器上运行时，总是会出现以下错误：

我已经安装了scannotation库，但似乎没有任何变化。此外，我想pom.xml和ephephere.xml没有什么问题，因为所有其他学生都没有遇到过这个问题。

“我已经安装了scannotation库”。。。你是怎么安装的？在您的maven存储库中？在eclipse项目中？在我的maven repo中，通过：mvn install:install file-Dfile=scannotation-1.0.2.jar-DgroupId=org.scannotation-DartifactId=scannotation-Dversion=1.0.2-dpackage=jar-DgeneratePom=true在eclipse中是否尝试运行类似“更新maven依赖项”的东西（我不知道如何运行它，因为我不使用eclipse，但我知道它存在，并且它经常解决eclipse maven集成中的奇怪错误）。
