尝试测试Jersey Web服务时出错

java.lang.NoClassDefFoundError: groovy/lang/GroovyObject
Caused by: java.lang.ClassNotFoundException: groovy.lang.GroovyObject

。

import static com.jayway.restassured.RestAssured.expect;
import static com.jayway.restassured.RestAssured.get;
import static org.hamcrest.CoreMatchers.equalTo;
import static org.hamcrest.CoreMatchers.nullValue;

import org.junit.Test;

public class SimpleTest  {

    @Test
    public void testUserFetchesSuccess() {
        expect().
                body("id", equalTo("1")).
                when().
                get("/service");
    }

}

这是什么意思？怎么解决？

更新

我下载并安装了groovy-all。现在我得到：
