Jetifier issue when using AndroidX

[virengujariya]

Failed to transform '/Users/latergram/.gradle/caches/modules-2/files-2.1/org.parceler/parceler/1.1.11/98501bf35dc8296db0e31146ddd26c57b3952ef4/parceler-1.1.11.jar' using Jetifier. Reason: The given artifact contains a string literal with a package reference 'android.support.v4.widget' that cannot be safely rewritten. Libraries using reflection such as annotation processors need to be updated manually to add support for androidx.. (Run with --stacktrace for more details.) To disable Jetifier, set android.enableJetifier=false in your gradle.properties file.

Now I need to keep enableJetifier set to true for dagger to work so can't set it to false

@virengujariya, admittedly I havent been able to focus on the androidx stuff... do you have the ability to put together a quick project to demonstrate this issue so I can troubleshoot it?

[virengujariya]

@johncarl81 When creating new project I realized it works fine there. I think it could be a cache issue. Trying every possible options to clean cache and re build but so far no luck. Will keep looking and update if found fix.

Looks like you'll have to remove use of android.support.v4.widget Couple of references that could be helpful

Same issue here. @virengujariya Have you started using AS 3.3.0-b3 or AS 3.4.0-a3? I suppose that begin from these AS versions Jetifier checks string literals which contain support library references, and fail if yes. Parceler have transfuse dependency which contain 'android.support.v4.app.*' literals in AndroidLiterals.java and I think that its the main reason. @johncarl81 I'll create empty project which reproduce the error.

@johncarl81 https://github.com/SunnyDayDev/error-showcase-parceler-androidx Try run the project and you'll get the error.

[virengujariya]

@SunnyDayDev It still fails for same reason on AS 3.3 beta-3 Did it work for you?

[johncarl81]

Was able to reproduce and I found the issue (thanks for a test case!)... here's the offending line of code from Transfuse: https://github.com/johncarl81/transfuse/blob/f892304a0306b5bb6f3f679c703b5075d3af6c99/transfuse-support/src/main/java/org/androidtransfuse/adapter/element/ASTElementFactory.java#L70 I think we can remove these lines because the issue has been resolved.

Ok, issued a fix and pushed out parceler 1.1.12-SNAPSHOT to maven central if you want to try it out @SunnyDayDev @virengujariya

BTW, here's how to try it out wiht @SunnyDayDev's example project:

Thanks @johncarl81

[SunnyDayDev]

@johncarl81, it's working fine) Thanks!

[jbarr21]

@johncarl81 any chance we could get a non-snapshot release with this fix?

[johncarl81]

Sure, I was thinking about waiting for the gradle plugin to leave beta, but my arm could be twisted.... I'll try to release 1.1.12 this evening/weekend.

[johncarl81]

Ok, just released 1.1.12 with this fix.
