Robolectric 4.3.1失败，并显示消息：Android 29需要Java 9（具有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。

我已将android.enableUnitTestBinaryResources=true添加到gradle.properties中，并在build.gradle中配置了testOptions.unitTests.includeAndroidResources = true。

我的测试跑步者是Robolectric 4.x文档中指定的AndroidJUnit4::class。

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

此外，仅从Gradle 6.0起，才支持使用JDK 13进行构建。
