androidX jetifier - Is there a way to ignore jetifying a .JAR?

Question

Trying to update my app to androidX dependencies. Followed instructions here, and compilation failed. The error came from JetifyTransform task failing to process a certain .JAR dependency (FYI - Samsungs Spass SDK) :

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:kaptGenerateStubsStandardNo_vendorDebugKotlin'.
> Could not resolve all artifacts for configuration ':app:standardNo_vendorDebugCompileClasspath'.
   > Failed to transform file 'pass-v1.2.2.jar' to match attributes {artifactType=processed-jar} using transform JetifyTransform
      > Failed to transform '/Users/hanandann/StudioProjects/ArnakPaymentsAndroid/Payments/app/libs/pass-v1.2.2.jar' using Jetifier. Reason: null. (Run with --stacktrace for more details.)

Trying to jetify with jetifier-standalone tool had similar results:

Hanans-MacBook-Pro:bin hanandann$ ./jetifier-standalone -i /Users/hanandann/StudioProjects/.../app/libs/pass-v1.2.2.jar -o /Users/hanandann/StudioProjects/.../app/libs/pass-v1.2.2jet.jar

Now, I don't really mind if SDK's don't get jetified, so I tried setting android.enableJetifier=false in my gradle.properties file, but compilation failed again for a different reason- SupportMapFragment isn't compatible with androidX yet as is reported here

So I'm stuck. With jetify the .JAR won't transform. with it - SupportMapFarg is incompatible.

Any suggestions?

P.S. you know what would be nice? if there was an ignore option for the jetifying function

I got same error because some lib jar file was "malformed" or something, which was a deprecation warning in Gradle 4 and a fatal error in Gradle 5. Downgrading to Gradle 4 solved the issue. – Amylose

Answer 1

added this to gradle.properties:

android.jetifier.blacklist = pass

as suggested by folks at google here.

Be warned - this feature is experimental and unsupported.

Update- current syntax is android.jetifier.ignorelist={your.ignored.lib} as Suggested by @YaMiN

This works for me and says "WARNING: The option setting 'android.jetifier.blacklist=pass' is experimental and unsupported.". Thanks. – Clammy

This does absolutely nothing. – Stripe

Any equivalent options for Xamarin android? – Unbiased

Answer 2

Currently android.jetifier.blacklist is deprecated.

It was removed in version 7.0 of the Android Gradle plugin. This property has been replaced by android.jetifier.ignorelist

Answer 3

Add this in project's gradle.properties: android.jetifier.blacklist =xx.aar,yy.jar split the black list with comma

update on 2022/06/07

If you use gradle 7, it change to android.jetifier.ignorelist

Answer 4

If you need to ignore just a specific .jar file from the jetifier. You can add the file name in the gradle.properties like on the last line from this example.

android.useAndroidX=true
android.enableJetifier=true
android.jetifier.blacklist=liblinphone-4.0.1-debug-symbols.jar
