How do I build this project?

[nitrocode]

I made the following changes

• signingConfigs and keystoreProperties in the app/build.gradle because I don't have this file
• I had to bump the gradle version to 4.2.0 in build.gradle
• gradle/wrapper/gradle-wrapper.properties we bumped up gradle to 7.1

I ran gradlew.bat build and get this error

> Task :app:processDebugMainManifest FAILED

FAILURE: Build failed with an exception.

* 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 @2679b9a0
