I have taken over an ex-employees project and I have been trying to make it run since past two days. However, the error I got today took a complete day but is still unsolvable. I have been getting parameter specified as non null is null for compileSdkVersion in build.gradle of one of the sub projects. The main build.gradle has the required Sdk versions specified but this is still throwing error.

This is the code of sub build.gradle.
This is the error message I am getting.
- Where: Build file 'D:\xxx\cleanaway-myview-app\driversapp\build.gradle' line: 39
- What went wrong: A problem occurred evaluating project ':driversapp'.
Parameter specified as non-null is null: method com.android.build.gradle.internal.dsl.BaseAppModuleExtension.compileSdkVersion, parameter version
CodePudding user response：
The following fields don't make sense:
compileSdkVersion compileSdk
minSdkVersion minSdk
targetSdkVersion targetSdk
I think someone misunderstood the instruction that compileSdkVersion can be replaced with compileSdk. Because you need to put actual numbers there, for example
compileSdkVersion 31
minSdkVersion 28
targetSdkVersion 31
which would be the old way. The new way
compileSdk 31
minSdk 28
targetSdk 31
not sure if the old way still works. In any case you need to put actual numbers there. Which ones you want for your project is up to you. compileSdk and targetSdk it's usually best to use the highest possible and minSdk the minimum android version you want to support.
