eclipse下ant的问题!!!!
我用的是Eclipse3.2,使用Middlegen的Eclipse插件创建Pojo类和hbm.xml文件。(版本是middlegenide_1.3.3.zip), 而且相应的hibernate、ant等插件都正确安装,一直都好好的,不知道为什么“运行-->ant构建”现在不能用了!!!!以前“运行-->ant构建”是“绿色”的,运行不会出错,现在“运行-->ant构建”是“灰色”的,运行就提示“Middlegen couldn't find any relations between any tables. This may be intentional from the design of the database, but it may also be because you have incorrectly defined the relationships. It could also be because the JDBC driver you're using doesn't correctly implement DatabaseMetaData. See the samples (for an example on how to define relationships) and verify that your driver correctly implements DatabaseMetaData.”
bulid.xml也一直正常,没有改过,不知为什么突然就用不了了??
高手指教!!!!帮帮忙!!!!谢谢!!
