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.

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

我的测试运行ner 是 AndroidJUnit4::class，如 Robolectric 4.x 文档中所述。

Answer 1

Robolectric 目前只能识别 JDK 具有正确格式的版本字符串 (X.XX.XX)： https://github.com/robolectric/robolectric/issues/5303#issuecomment-547029317.

此外，只有 Gradle 6.0 及更高版本才支持使用 JDK 13 构建。

Answer 2

订购 Robolectric 版本时出现问题，特别是 4.3.1。只需将 Robolectric 版本升级到 4.5.1 或更高版本。

 implementation "org.robolectric:robolectric:4.5.1"

谢谢。
