Missing classes when R8 minify is enabled

[lebeshev]

Describe the bug
When building app with

    isMinifyEnabled = true
    proguardFiles("proguard-android-optimize.txt", "proguard-rules.pro")

and

dependencies {
    implementation("com.microsoft.identity.client:msal:4.0.0")
}

R8 produces following warnings:

Missing class edu.umd.cs.findbugs.annotations.NonNull (referenced from: java.util.Map com.microsoft.identity.common.java.challengehandlers.PKeyAuthChallenge.getChallengeHeaderWithSignedJwt(com.microsoft.identity.common.java.challengehandlers.IDeviceCertificate) and 13 other contexts)
Missing class edu.umd.cs.findbugs.annotations.Nullable (referenced from: android.app.Activity com.microsoft.identity.common.internal.platform.AndroidPlatformUtil.mActivity and 257 other contexts)

Smartphone (please complete the following information):

• Android Version: API 31
• MSAL Version: 4.0.0

[argenkiwi]

I have upgraded to AGP 8.0 and I get an error when making a build with R8 enabled. I believe it is related to this change.

I am on v.4.2.0. Please advice on what rules I should apply to be able to finish the build process without these errors.

[krolikm]

Same issue in v4.5.0. I was able to build the app with these rules in proguard-rules.pro:

-dontwarn edu.umd.cs.findbugs.annotations.NonNull
-dontwarn edu.umd.cs.findbugs.annotations.Nullable
-dontwarn edu.umd.cs.findbugs.annotations.SuppressFBWarnings

[dwane13]

Same with 4.6.1

This library should package R8 rules in consumerProguardFiles, so users do not face this issue.
