我对Play框架和Couchbase并不熟悉，我正在尝试为我的Play框架应用程序编写一个基本的Junit测试用例，但这给了我NoSuchMethodError:com.couchbase.client.java.env.DefaultCouchbaseEnvironment。我在测试用例中没有在任何地方引用CouchbaseEnvironment，那么为什么会出现此错误？我正在使用sbt test命令通过控制台执行测试用例。
import org.junit.Test;
import play.test.WithApplication;
import static org.junit.Assert.assertEquals;
public class AppControllerTest extends WithApplication {
@Test
public void testMethod() {
boolean t = true;
assertEquals(true, t);
}
}

这是版本不兼容的问题。 SBT正在拉CouchbaseMock，该CouchbaseMock比我使用的Couchbase java-client (2.4.2)还早于java-client。
我将(2.7.7)版本更改为Couchbase java-client，因为我想在测试用例中使用CouchbaseMock。
也可以通过从2.4.2删除build.sbt的CouchbaseMock行来解决
