gradle junit和错误：找不到符号

Question

我试图在我编译并部署到aws Lambda的概念证明类上从gradle运行一个简单的junit测试。类auth.java接受一个POJO，只有一个属性email。它自己编译得很好，并在AWS上工作。但是，当我跑的时候：

gradle build

我收到以下错误：

Auth.java:6: error: cannot find symbol
System.out.println(payload.email);
symbol:   variable email
location: variable payload of type Object
1 error
:compileJava FAILED

如果我system.out.println（payload.email）；从testauth.java中访问对象的属性没有问题。我是不是没有掌握一些关键的java或gradle概念？我已经重构了5种不同的方式，但我总是收到这找不到符号错误。有人有什么想法吗？这是我的简化代码。

package works.valt.api;

public class Auth {

    public Auth(Object payload) {
        System.out.println(payload.email);
    }

}

import org.junit.Test;
import org.junit.Before;
import static org.junit.Assert.assertEquals;
import works.valt.api.Auth;

public class TestAuth {

    public class Payload {
      public String email = "[e-mail]";
    }

    private Payload payload;

    // create payload
    @Before
    public void setUp() {
      this.payload = new Payload();
    }    

   @Test
   public void testResponse() {
      Auth response = new Auth(this.payload);
   }

}

Build.Gradle

apply plugin: 'java'

repositories {
    mavenCentral()
}

dependencies {
    testCompile 'junit:junit:4.12'
}

test {
    testLogging.showStandardStreams = true
}

task buildZip(type: Zip) {
    from compileJava
    from processResources              
    into('lib') {
        from configurations.runtime
    }           
}

build.dependsOn buildZip

public Auth(Object payload) {
    System.out.println(payload.email);
}

Auth.java:6: error: cannot find symbol
System.out.println(payload.email);
symbol:   variable email
location:
variable payload of type Object
