我org.assertj:assertj-core:3.6.2用来测试我的android项目。根据官方规定，我应该将 java 8 与 assertj 3.x 一起使用。
这是我的测试类，我正在尝试验证单击执行的代码何时可以开始预期的活动。
import android.content.Intent;
import org.assertj.core.api.Assertions;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.robolectric.Robolectric;
import org.robolectric.RobolectricTestRunner;
import org.robolectric.Shadows;
import org.robolectric.annotation.Config;
import org.robolectric.shadows.ShadowActivity;
@RunWith(RobolectricTestRunner.class)
@Config(constants = BuildConfig.class, sdk = 21)
public class LoginActivityTest {
@Test
public void testBtnLogin(){
LoginActivity loginActivity = Robolectric.setupActivity(LoginActivity.class);
loginActivity.findViewById(R.id.btnLogin)
.performClick();
Intent expectedIntent = new Intent(loginActivity,MainActivity.class);
ShadowActivity shadowActivity = Shadows.shadowOf(loginActivity);
Intent actualIntent = shadowActivity.getNextStartedActivity();
Assertions.assertThat(actualIntent).isEqualTo(expectedIntent);
}
}
但是当我运行测试时，我得到了这个错误：
:app:compileDebugUnitTestJavaWithJavac (Thread[Daemon worker,5,main]) started.
:app:compileDebugUnitTestJavaWithJavac

我在谷歌上搜索，发现它可能是由错误版本的 java 引起的（我真的不确定）。
以下是有关我的 java 配置的一些信息：
$ java -version
java version "1.8.0_112"
Java(TM) SE Runtime Environment (build 1.8.0_112-b15)
Java HotSpot(TM) 64-Bit Server VM (build 25.112-b15, mixed mode)
$ javac -version
javac 1.8.0_112
$ update-alternatives --config java
There are 2 choices for the alternative java (providing /usr/bin/java).
Selection Path Priority Status
------------------------------------------------------------
* 0 /usr/lib/jvm/java-7-openjdk-amd64/jre/bin/java 1071 auto mode
1 /home/java/jdk1.8.0_112/bin/java 300 manual mode
2 /usr/lib/jvm/java-7-openjdk-amd64/jre/bin/java 1071 manual mode
并且在项目结构中，我还将JDK设置为jdk1.8.0_112
如果是java版本引起的，应该怎么办？如果没有，那我该怎么办？
