Grails 2.2到2.3 - 运行forked test-app时出错:无法加载grails构建监听器类

Question

我正在将我的项目从grails 2.2迁移到2.3,当我做test-app时(在IDEA 12.1.6上),我收到了这个错误

我的BuildConfig.groovy看起来像这样:

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"
    }
}

怎么了 ？

为了利用IntelliJ中新的Grails fork测试功能,您需要在IntelliJ安装目录下找到grails-rt.jar文件,并将其复制到grails项目lib目录,或者将其提供给你的grails应用程序通过类路径.

就我而言,在Mac OS X上,grails-rt.jar文件位于:

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

我把这个文件复制到了~/MyGrailsApp/lib.
