我遇到了以下问题。我试图使用Maven或Ivy插件为eclipse从pom.xml文件生成deps并运行GWT webapp。我已经检查过100次spring-tx在依赖项中。我正在使用所有3.1.3版本的spring。 jar就在类路径上。我手动检查了maven依赖库列表（对于Ivy来说是pom.xml *）。 我还检查了META-INF / *文件在jar中的位置并没有损坏。
我不是使用maven来构建/运行任何东西，而是使用eclipse调试目标来运行GWT webapp。
我在互联网上看到很多线程但没有解决我的问题。相关：http://jira.codehaus.org/browse/MASSEMBLY-360？
有人能指出这个问题可能的根本原因吗？
