即使使用Java 8颤振医生问题

Question

我正在使用Ubuntu 18.04LTS，Android Studio v3.0.1，已安装最新的Android SDK API 30和29，Android SDK构建工具，平台工具和命令行工具（最新），已降级为Java jdk1.8，已安装VSCode上的Dart插件，Android Studio上已安装Dart和Flutter插件，并在终端上使用snap安装了flutter。

但是当我运行 User Text Effort Nunique 0 user122 TextA 2 Weeks 3 1 user124 TextB 2 Weeks 3 2 user125 TextC 3 Weeks 1 3 user126 TextD 2 Weeks 3 4 user126 TextE 2 Weeks 3 时，我得到了

flutter doctor

它说即使我安装了插件并重新启动android studio，插件也没有安装。

当我运行Doctor summary (to see all details, run flutter doctor -v): [✓] Flutter (Channel stable, 1.22.0, on Linux, locale en_IN) [!] Android toolchain - develop for Android devices (Android SDK version 29.0.1) ! Some Android licenses not accepted. To resolve this, run: flutter doctor --android-licenses [✓] Android Studio (version 3.0) [!] Android Studio ✗ Flutter plugin not installed; this adds Flutter specific functionality. ✗ Dart plugin not installed; this adds Dart specific functionality. [✓] VS Code (version 1.44.0) [!] Connected device ! No devices available ! Doctor found issues in 3 categories. 时，我会在终端中键入flutter doctor --android-licenses来获得所有许可证并接受它们，即使在此之后运行Y时，它仍然会给我相同的结果。

Java 9出现问题，因此将JDK降级到1.8，但问题仍未解决。

运行以下命令

$ export JAVA_HOME=`/usr/libexec/java_home -v 1.8*`
$ flutter doctor --android-licenses
