运行我的Gradle Liquibase插件时，我在哪里放置MySql JAR依赖项？

Question

我使用的摇篮2.7在Windows 7我想一旦运行

gradle build 

所以我有下面的代码在我的build.gradle文件

// In this section you declare the dependencies for your production and test code 
dependencies { 
    // The production code uses the SLF4J logging API at compile time 
    compile (

     'commons-beanutils:commons-beanutils:1.8.3', 
     'commons-collections:commons-collections:3.2.1',

     'org.springframework:spring-webmvc:4.2.1.RELEASE' 
    ) 

... 
liquibase { 
    activities { 
    main { 
     File propsFile = new File("${project.rootDir}/src/main/resources/liquibase.properties") 
     Properties properties = new Properties() 
     properties.load(new FileInputStream(propsFile)) 
     changeLogFile 'src/main/resources/db.changelog-1.0.xml' 
     url 'jdbc:mysql://localhost:3306/my_db' 
     username 'username' 
     password 'poassword' 
    } 
    runList = "main" 
    } 
} 

testClasses.dependsOn update 

，但我得到运行我Liquibase插件以下错误

For more information, use the --logLevel flag 
:update FAILED 

FAILURE: Build failed with an exception. 

* What went wrong: 
Execution failed for task ':update'. 
> liquibase.exception.LiquibaseException: Unexpected error running Liquibase: java.lang.RuntimeException: Cannot find database driver: com.mysql.jdbc.Driver 

鉴于司机在我的类路径（见上述“‘的mysql：mysql的连接器的Java：5.1.36’”在depencney列表），在那里它需要去让Liquibase认识它？

编辑：％的建议，我想下面的

buildscript { 
    repositories { 
    mavenCentral() 
    } 
    dependencies { 
    classpath("mysql:mysql-connector-java:5.1.36") 
    } 
} 

liquibase { 
    activities { 
    main { 
     File propsFile = new File("${project.rootDir}/src/main/resources/liquibase.properties") 
     Properties properties = new Properties() 
     properties.load(new FileInputStream(propsFile)) 
     changeLogFile 'src/main/resources/db.changelog-1.0.xml' 
     url 'jdbc:mysql://localhost:3306/xxx_db' 
     username 'xxx' 
     password 'xxx' 
    } 
    runList = "main" 
    } 
} 

testClasses.dependsOn update 

，但得到下面的错误...

$ gradle build

望着liquibase插件源，它看起来像你会需要添加您的依赖到您的buildscript

buildscript { 
    repositories { 
     mavenCentral() 
    } 
    dependencies { 
     classpath 'mysql:mysql-connector-java:5.1.36' 
    } 
}
