This is clearly because it needs Java 11, and it got compiled in Java 8.
However, when I check all places I see, they are all set to Java 11. The below is what I have checked
1. In the Terminal environment
java -version
openjdk version "11.0.12" 2021-07-20 LTS
OpenJDK Runtime Environment Zulu11.50+19-CA (build 11.0.12+7-LTS)
OpenJDK 64-Bit Server VM Zulu11.50+19-CA (build 11.0.12+7-LTS, mixed mode)
elisha.lye@C02FF0VFQ05N k5-compose %
2. In the Gradle setting
3. In the Java Compiler
4. In the JRE Setting
Where do I miss setting my Java Run Time?
Solution
1 - Is for your OS and terminal, nothing common with the project
2 - Is the JDK for running Gradle. For Gradle daemon itself, not for the project
3 - Is the project's bytecode version which could be overwritten in module.
4 - Is the Runtime environment for the IDE itself.
So, you need to edit Project Structure > Project setting > Project > Language level See https://www.jetbrains.com/help/idea/sdk.html#set-up-jdk
