我每次执行grails运行应用程序时都得到 ClassNotFoundException:oracle.jdbc.OracleDriver，而之前没有做完--refresh-dependencies(我的项目/ lib中有oracle驱动程序.jar)。
我在here和其他地方也看到过类似的问题，答案似乎总是在运行--refresh-depdencies
但是，我发现执行此操作仅在运行--refresh-dependencies之后仅运行一次。随后的任何时候，我运行应用程序时，都会再次获得 ClassNotFoundException :oracle.jdbc.OracleDriver，直到再次运行--refresh-dependencies。通过每次我要运行应用程序时都运行--refresh-dependencies，我仍然可以运行，但这很烦人。
我正在运行grails 2.3.0。
在运行应用程序之前立即完成输出而未完成--refresh-dependencies:| Loading Grails 2.3.0

最佳答案
我不认为这是我自己的问题的“答案”，但是如果有其他人遇到此问题，我将其发布在此处，作为可能的解决方法。
通过通过BuildConfig.groovy而不是使用/ lib文件夹将我的Oracle驱动程序拉入，可以使此问题停止发生。
我不认为这是一种解决方案的原因是，为了做到这一点，您需要一个可以在其中找到oracle驱动程序 Artifact 的存储库，并且它不在任何公共(public)存储库中，也不允许由于部分原因是“s”甲骨文。
我的公司有一个我可以使用的私有(private)存储库，该存储库由我们的CI服务器共享，并且该解决方案仅适用于那些可以访问某种私有(private)存储库的存储库。我在BuildConfig.groovy中输入的内容几乎是您可能期望的:
runtime "com.oracle:ojdbc6:11.2.0.1.0"
那些由于其中没有oracle驱动程序jar可用的存储库而无法使用此解决方案的用户，仍将需要解决使用/ lib时出现的问题的解决方案。
关于grails - Grails无法加载oracle.jdbc.driver.OracleDriver，并且--refresh-dependencies不起作用，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/21123305/
