如何在Gradle中使用测试结构引用或链接Java src

Question

我刚接触gradle当前我在编译测试类时遇到了问题我在测试类中引用Java类来测试程序，但我无法编译。问题我不了解如何将Java src结构与测试结构链接或引用。有人可以帮我解决问题。

下面我提供了Src和测试包结构和编译问题的截图。

Java Src和测试结构

编译错误

build.properties

apply plugin: 'java'

sourceCompatibility = '1.7'
[compileJava, compileTestJava]*.options*.encoding = 'UTF-8'

// NetBeans will automatically add "run" and "debug" tasks relying on the
// "mainClass" property. You may however define the property prior executing
// tasks by passing a "-PmainClass=<QUALIFIED_CLASS_NAME>" argument.
//
// Note however, that you may define your own "run" and "debug" task if you
// prefer. In this case NetBeans will not add these tasks but you may rely on
// your own implementation.
if (!hasProperty('mainClass')) {
    ext.mainClass = ''
}

jar {
    manifest {
        attributes 'Main-Class': 'com.gradle.shopcart.ShopCartApp'
    }
}

repositories {
    mavenCentral()
    // You may define additional repositories, or even remove "mavenCentral()".
    // Read more about repositories here:
    //   http://www.gradle.org/docs/current/userguide/dependency_management.html#sec:repositories
}

dependencies {
    // TODO: Add dependencies here ...
    // You can read more about how to add dependency here:
    //   http://www.gradle.org/docs/current/userguide/dependency_management.html#sec:how_to_declare_your_dependencies
    testCompile group: 'junit', name: 'junit', version: '4.12'

}

修改::

我使用netbeans，在gradle插件的帮助下，我在下面创建了这个项目结构，你可以找到截图。如果我错过了什么，请纠正我。
