为什么在 grails 中创建 war 文件时，有时 war 中缺少 jdbc 驱动程序？
Why does jdbc driver missing in war some times when a war file created in grails?
当我 运行 我的 grails 应用程序处于开发模式时一切正常。但是当我创建一个 war 文件并将其部署到网络服务器时，出现以下错误？

当我打开 war 存档时，JDBC 驱动程序 ojdbc6.jar 文件丢失。我以前的工作部署在 war 存档库目录中有 jar 文件。可能是什么原因？我使用 grails 版本 2.4.4.

在您的 buildconfig.groovy 中试试这个，然后告诉我。我已经为我在 Grails 下生产的许多项目改进了我的 buildconfig.groovy，这是 Grails 2.4 之前的问题，如果我不使用我告诉你的配置，war 就不会'不包含罐子。我想还有其他解决方案，但我的解决方案是从我在依赖项块中告诉你的存储库中获取的。我将 jdbc41 用于 postgreSQL，但对于 ojdb，我发现您可以改用 'cn.guoyukun.jdbc:oracle-ojdbc6:jar:11.2.0.3.0'。无论如何，您可以在 mvnrepository 查看最适合您的版本。
