tools:overrrideLibrary doesn't recognize library and forces to use AndroidX

Question

My Android Studio project has minSdk 10. It still uses legacy libraries. Indeed the build.gradle file contains:

android.useAndroidX=false
android.enableJetifier=false

I imported a Maven legacy dependency that requires minSdk 14. implementation 'com.android.support:webkit:28.0.0'. Obliviously I got a compiling error. Since I don't want to increase the project minSDK, I tried to ignore the error. To do that, I added this line to the Manifest:

<uses-sdk
        tools:overrideLibrary="com.android.support.webkit" />

The problem is that I still can't compile the project since the error message asks to do "ovverrideLibray" for the new AndroidX library, and not for the old legacy library!

use tools:overrideLibrary="androidx.webkit" to force usage

(I just want to ignore a minSdk library error, who cares if the library is new or old!)

How can I solve this problem?

This project targets some old devices, and switching to AndroidX would be worse. I just want to add that legacy library ignoring the error.

Any solution? Thank you in advance.
