How to make field private final java.lang.String java.io.File.path accessible [duplicate]

Question

I have a big problem with an old project (Android Studio) of mine that I can no longer run on my new pc. How can I solve this problem?

* What went wrong:
Execution failed for task ':app:processDebugMainManifest'.
> Unable to make field private final java.lang.String java.io.File.path accessible: module java.base does not "opens java.io" to unnamed module @387a8b67

What Java version (JRE/JDK) do you have installed? I would not recommend to install a version higher than 11. For an old project it can make sense to install Java 8 and use it for building the project. — Robert

Had same problem with Flutter. I uninstalled Android Studio and Android SDK and reinstalled everything and upgraded Flutter, without success. Then I created a new Flutter project and copied the sources from the old one, and this time it worked. — Jean G

You must be using JDK-16 which isn't supported yet, use the version below JDK-16, for example, I am using JDK-11 and it worked for me.
