我知道这是一个非常基本的问题，但我被困在这里，我不知道为什么。所以情况就是这样：我正在尝试连接 My Grails 应用程序。我将 .jar 放在 lib 目录中，并将此代码放在 BuildConfig.groovy 中：

 dependencies {
    // specify dependencies here under either 'build', 'compile', 'runtime', 'test' or 'provided' scopes e.g.
    // runtime 'mysql:mysql-connector-java:5.1.27'
     runtime 'mariadb:mariadb-java-client:1.1.5'
    // runtime 'org.postgresql:postgresql:9.3-1100-jdbc41'
}

这在我的 DataSource.groovy 中：

production {
    dataSource {
        dbCreate = "update"
        url = "jdbc:mariadb://localhost/gTunes"
        driverClassName = "org.mariadb.jdbc.Driver"
        username = "root"
        password = ""
        pooled = true
        properties {
            maxActive = -1
            minEvictableIdleTimeMillis=1800000
            timeBetweenEvictionRunsMillis=1800000
            numTestsPerEvictionRun=3
            testOnBorrow=true
            testWhileIdle=true
            testOnReturn=true
            validationQuery="SELECT 1"
        }
    }
}

这是我得到的错误（基本上是ClassNotFoundException：

看起来 1.1.5 版在 maven repo 中不存在。您应该尝试使用 1.1.1 并启动应用程序。

这是我使用的一个，来自 Maven，因此没有 jar - 正如评论中所建议的那样。

dependencies {
    runtime    'org.mariadb.jdbc: mariadb-java-client:1.5.0-RC1'        
    /*1.6.0-SNAPSHOT,,,,1.5.0-RC1,,,1.4.6*/
}

或 Jar 连接字符串

dependencies {
    runtime    'jdbc: mariadb-java-client:1.5.0-RC1' 
}

或者 Maven 严格来说

<dependency>
    <groupId>org.mariadb.jdbc</groupId>
    <artifactId>mariadb-java-client</artifactId>
    <version>xxx</version>
</dependency>

请务必仔细检查这种情况的源文档：
