Robolectric 4.3.1 失败并显示消息：Android 29 需要 Java 9（有 Java 1）

Question

我正在尝试通过 robolectric 运行我的 android 测试，但它收到以下错误消息：

我安装的 JDK 版本是 13。

我已经添加android.enableUnitTestBinaryResources=true到 gradle.properties 并testOptions.unitTests.includeAndroidResources = true在 build.gradle 中配置。

我的测试运行器AndroidJUnit4::class在 Robolectric 4.x 文档中指定。

Robolectric 目前仅识别具有正确格式 (X.XX.XX) 版本字符串的 JDK： https: //github.com/robolectric/robolectric/issues/5303#issuecomment-547029317。

此外，仅 Gradle 6.0 及以上版本支持使用 JDK 13 进行构建。
