Grails中的連接錯誤

Question

運行grail應用程序時出現以下錯誤。我嘗試了各種各樣的東西，但錯誤並沒有消失。

任何人都可以請幫忙。

請檢查您的"grails-app/conf/BuildConfig.groovy"

我想你可能會不小心編輯它的。看起來像msql-connector被放置在錯誤的地方。

dependencies { 
    // specify dependencies here under either 'build', 'compile', 'runtime', 'test' or 'provided' scopes eg. 
    runtime 'mysql:mysql-connector-java:5.1.16' // RIGHT PLACE 
} 

plugins { 
    runtime ":hibernate:$grailsVersion" 
    runtime ":jquery:1.7.1" 
    runtime ":resources:1.1.5" 

    build ":tomcat:$grailsVersion" 
    //runtime ':mysql-connector-java:5.1.16' // WRONG PLACE, IF YOU SAW HERE. 
}
