我遇到了以下问题。我正在尝试使用 Maven 或 Ivy 插件来从 pom.xml 文件生成 deps 并运行 GWT webapp。我已经检查了 100 次 spring-tx 在依赖项中。我正在使用所有 3.1.3 版本的 spring。罐子在类路径上。我手动检查了 maven 依赖库列表（常春藤的 pom.xml*）。我还检查了 META-INF/* 文件是否在 jar 中并且没有损坏。
我没有使用 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，但没有一个能解决我的问题。相关：http: //jira.codehaus.org/browse/MASSEMBLY-360？
有人可以指出这个问题的任何可能的根本原因吗？
