推荐答案

您的项目可能未配置为您的配置。尝试删除 .classpath 和 .project 并从现有源重新创建项目。也删除任何eclipse内部dirs，如果他们不小心提交到SVN，如 .settings 以dot开头。

Your project may be configured not for your comp. Try to remove .classpath and .project and recreate the project from existed sources. Also remove any eclipse internal dirs if they are accidentally committed to the SVN such as .settings that starts with dot.
