Tomcat 在grails-2.2.1中找不到默认容器

由于grails run app命令，我尝试启动web应用程序，但出现以下错误：

| Configuring classpath

| Error SLF4J: Class path contains multiple SLF4J bindings.

| Compiling 2 source files.....

| Compiling 2 source files.....

| Error No default container found. Please install a container plugin such as 'tomcat' first.

BuildConfig.groovy包含

build:tomcat:$grailsVersion“

BuildConfig.groovy:

grails.project.class.dir = "target/classes"
grails.project.test.class.dir = "target/test-classes"
grails.project.test.reports.dir = "target/test-reports"
grails.project.target.level = 1.6
grails.project.source.level = 1.6
//grails.project.war.file = "target/${appName}-${appVersion}.war"

// uncomment (and adjust settings) to fork the JVM to isolate classpaths
//grails.project.fork = [
  // run: [maxMemory:1024, minMemory:64, debug:false, maxPerm:256]
//]

// Plugin Directory Location
grails.project.plugins.dir="./plugins"


grails.project.dependency.resolution = {
    // inherit Grails' default dependencies
    inherits("global") {
        // specify dependency exclusions here; for example, uncomment this to disable ehcache:
        // excludes 'ehcache'
    }
    log "error" // log level of Ivy resolver, either 'error', 'warn', 'info', 'debug' or 'verbose'
    checksums true // Whether to verify checksums on resolve
    legacyResolve false // whether to do a secondary resolve on plugin installation, not advised and here for backwards compatibility

    repositories {
        inherits true // Whether to inherit repository definitions from plugins

        grailsPlugins()

        mavenLocal()
        mavenCentral()

        // uncomment these (or add new ones) to enable remote dependency resolution from public Maven repositories

    }
}

我尝试了“GrailsClean”和“GrailsRefreshDependencies”，但我得到了 错误

|错误未找到默认容器。请先安装容器插件，如“tomcat”。

使用grails run app

我不知道如何解决这个问题

谢谢你的帮助
