我正在尝试将我的 Grails 应用程序连接到 Firebird 数据库。
我在用：
- 圣杯 2.2.1
- JDK 1.7
- 火鸟 2.5.2
- 捷鸟 2.2.2
到目前为止，这就是我所做的：
- 我从http://www.firebirdsql.org/en/jdbc-driver/下载了 Jaybird-2.2.2JDK_1.7.zip
- 我解压缩了这个文件并将 jaybird-2.2.2.jar 复制到我的应用程序的 lib 文件夹中。
- 在 BuildConfig.groovy 中，我添加
runtime "org.firebirdsql.jdbc:jaybird:2.2.2"了依赖项部分。 - 我编辑了 DataSource.groovy，如下所述。
数据源部分：
dataSource {
pooled = false
driverClassName = "org.firebirdsql.jdbc.FBDriver"
dialect = "org.hibernate.dialect.FirebirdDialect"
username = "SYSDBA"
password = "masterkey"
}
休眠部分：
hibernate {
cache.use_second_level_cache = true
cache.use_query_cache = true
cache.provider_class = 'org.firebirdsql.pool.FBSimpleDataSource'
}
（我在不同的场合也有过cache.region.factory_class = 'net.sf.ehcache.hibernate.EhCacheRegionFactory上述cache.provider_class = 'com.opensymphony.oscache.hibernate.OSCacheProvider'部分，但都没有任何区别。）
运行我的 Grails 应用程序时，启动失败并出现一个巨大的错误，归结为以下消息：
java.lang.IllegalStateException: Could not load JDBC driver class [org.firebirdsql.jdbc.FBDriver]
我已经在网上搜索了很多地方，但是我在任何地方都找不到工作 Grails/Firebird 配置的示例。有一个涉及复制 minij2ee.jar 的修复程序，但这是针对不同的错误消息。此外，人们建议清空 .grails 文件夹——我试过了，但无济于事。
有人可以建议，我怎样才能让 Grails 与 Firebird 一起工作？
这是整个例外，尽管它似乎在启动过程中重复了几次：
