Grails 2.2 to 2.3 - 運行分叉測試應用程序時出錯：無法加載grails生成監聽器類

Question

我正在將我的項目從grails 2.2遷移到2.3，當我測試應用程序時（在IDEA 12.1.6上），我得到了這個錯誤

我BuildConfig.groovy是這樣的：

grails.servlet.version = "3.0" 
grails.project.class.dir = "target/classes" 
grails.project.test.class.dir = "target/test-classes" 
grails.project.test.reports.dir = "target/test-reports" 
grails.project.work.dir = "target/work" 
grails.project.target.level = 1.6 
grails.project.source.level = 1.6 

grails.project.fork = [ 
    test: [maxMemory: 768, minMemory: 64, debug: false, maxPerm: 256, daemon:true], 
    run: [maxMemory: 768, minMemory: 64, debug: false, maxPerm: 256, forkReserve:false], 
    war: [maxMemory: 768, minMemory: 64, debug: false, maxPerm: 256, forkReserve:false], 
    console: [maxMemory: 768, minMemory: 64, debug: false, maxPerm: 256] 
] 

grails.project.dependency.resolver = "maven" // or ivy 

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" 
    checksums true 
    legacyResolve false 

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

     grailsPlugins() 
     grailsHome() 
     mavenLocal() 
     grailsCentral() 
     mavenCentral() 
    } 

    dependencies { 
     runtime 'mysql:mysql-connector-java:5.1.24' 
    } 

    plugins { 
     build ":tomcat:7.0.42" 

     compile ":scaffolding:2.0.1" 
     compile ':cache:1.1.1' 

     runtime ":hibernate:3.6.10.2" // or ":hibernate4:4.1.11.2" 
     runtime ":jquery:1.10.2" 
     runtime ":resources:1.2.1" 
    } 
} 

有什麼不對？

爲了充分利用IntelliJ中新的Grails分支測試功能，您需要find the grails-rt.jar file under your IntelliJ installation directory，並將其複製到您的grails項目庫目錄中，或通過類路徑將其提供給您的Grails應用程序。

在我的情況下，在Mac OS X，Grails的-rt.jar的文件位於：

/Applications/IntelliJ\ IDEA\ 13.app/plugins/Grails/lib/grails-rt.jar 

，我複製該文件到~/MyGrailsApp/lib。
