grails 2.2.3和spock 0.7的classcast异常

Question

以下是我们正在做的事情，它在grails 2.0.0和spock 0.6 中起作用

一个简单的领域：

package com.grails
class User {
    String name, password
    def methodWithNoArguments(){
        return "Object: methodWithNoArguments"
    }
    static constraints = {
    }
}

单位规格：

package com.grails
import spock.lang.* 
import grails.test.mixin.TestFor 
import grails.test.mixin.Mock 
import grails.test.GrailsMock
@TestFor(UserController)  // testing for 
@Mock([User])             // collaborators class 
UserControllerSpec extends  Specification {
    // DOES NOT work in 2.2.3 spock 0.7,
    // WORKS in grails-2.0.0 spock 0.6
    def 'create a Domain collaborator using Mock'() {
        given: 'user'
        // can't mock this anymore, causes classcast exception.
        User user = Mock(User)
        user.methodWithNoArguments()  >> { "Mock: (3) methodWithNoArguments" }
        when: 'we call the method'
        def val1 = user.methodWithNoArguments()
        then: 'value should be from the mocked method'
        val1 == "Mock: (3) methodWithNoArguments"
    } }

上述情况导致grails 2.2.3和spock 0.7出现以下异常。注意（适用于grails-2.0.0和spock 0.6）

|java.lang.ClassCastException：com.grails.User不能转换为net.sf.cglib.proxy.Factory位于org.spockframework.mok.runtime.ProxyBasedMockFactory$CglibMockFactory.createMock（ProxyBasedMokFactory.java:93）位于org.spockframework.mok.runtime.ProxyBasedMockFactory.create（ProxyBasedMokFactory.java:49）网址：org.spockframework.mok.runtime.JavaMockFactory.create（JavaMockFactory.java:51）位于org.spockframework.mok.runtime.CompositeMockFactory.create（CompositeMockFactory.java:44）网址：org.spockframework.lang.SpecInternal.createMock（SpecInternal.java:47）网址：org.spockframework.lang.SpecInternal.createMockImpl（SpecInternal.java:282）网址：org.spockframework.lang.SpecInternal.MockImpl（SpecInternal.java:99）在com.grails.UserControllerSpec.create a Domain collaborator using Mock（UserControllerSpec.groovy:94）

想知道是否有一些不兼容的库，这里是BuildConfig.groovy

dependencies {
    test "org.spockframework:spock-grails-support:0.7-groovy-2.0"
}
plugins {
    runtime ":hibernate:$grailsVersion"
    runtime ":jquery:1.8.3"
    runtime ":resources:1.2"
    build ":tomcat:$grailsVersion"
    runtime ":database-migration:1.3.2"
    compile ':cache:1.0.1'
    test(":spock:0.7") {
        exclude "spock-grails-support"
    }
}

示例测试应用程序位于[e-mail]：nbostech/ggrails-spock-2.2.3.git

git checkout grails-2.0.0<2.0.0>/bin/grails测试应用程序--单元UserControllerSpec；//所有测试都通过

git结账主机<2.2.3>/bin/grails测试应用程序--单元UserControllerSpec；//其中一项测试失败。。

Grails和Spock mock不打算以这种方式混合。要么让它成为Grails @Mock，要么成为Spock Mock()。
