Grails引發H2 WebServlet加載錯誤

我想從我的Grails應用中刪除H2。在我BuildConfig.groovy：Grails引發H2 WebServlet加載錯誤

grails.project.dependency.resolution = { 
    inherits("global") { 
     excludes 'h2' 
    } 

    ... 
}

在我Datasource.groovy文件：

hibernate { 
    cache.use_second_level_cache = true 
    cache.use_query_cache = false 
    cache.region.factory_class = 'org.hibernate.cache.ehcache.EhCacheRegionFactory' 
    singleSession = true 
}

當我做了run-app我的應用程序運行在瀏覽器的罰款，但在控制檯中我看到下面的錯誤輸出：

H2自帶web servlet？！？ 這裏發生了什麼，我能做些什麼來解決它？
