运行 gradlew 测试时的机器人错误

Question

尝试运行gradlew test或gradlew testDebugUnitTest时出现机器人崩溃 有了这个错误

> Task :app:testDebugUnitTest 
WARNING: An illegal reflective access operation has occurred
WARNING: Illegal reflective access by org.robolectric.util.ReflectionHelpers$7 (file:/C:/Users/a.yasser/.gradle/caches/modules-2/files-2.1/org.robolectric/shadowapi/3.8/d638f001e81ef737bb35db2964312360cc996a94/shadowapi-3.8.jar)

ash.gaseelydriver.ui.activities.MainActivityTest > shouldNotBeNull FAILED
java.lang.NoClassDefFoundError
Caused by: java.lang.ClassNotFoundException
Caused by: java.lang.RuntimeException
Caused by: java.lang.IllegalArgumentException

仅当我从命令行运行时，才会发生此问题，我已经尝试了多种解决方案，但没有一个有效，包括

• 删除 .gradle 文件
• 删除 .idea\libraries
• 删除清理/重建项目
• 降级和升级机器人版本
• 将我的整个项目编译版本和 Taget SDK 升级到 28
• 将 gradle 升级到从 3.1.2 到 3.2.0 的版本

这是格拉德尔文件

下面是一个示例测试类

@RunWith(RobolectricTestRunner.class)
@Config(constants = BuildConfig.class, sdk = 27)
public class MainActivityTest {
private MainActivity activity;
@Before
public void setUp() {
activity = Robolectric.buildActivity(MainActivity.class).create()
.resume()
.get();
}
@Test
public void shouldNotBeNull() throws Exception {
assertNotNull(activity);
}

使用 CLI 时，gradle 将使用安装在您机器上的 java 版本。就我而言，安装在我机器上的 Java 版本是 10 版，Android 尚不支持该版本。 您的测试在 Android Studio 上运行，因为它使用了 Android 支持的嵌入式 JDK。 现在要解决您的问题，首先通过运行以下命令检查计算机上安装的 Java 版本：

java -version

如果版本 1.10.xxx，则应：

1. 通过此链接下载并安装 JDK 8。

2. 通过在 bash_profile中添加以下行(在 Mac 上(将环境变量JAVA_HOME指向已安装的 JDK 8 的新路径：

   导出JAVA_HOME = "$ (/USR/libexec/java_home -v 1.8(">

3. 通过新的终端窗口重新运行测试
