Multiple warnings "Ignoring InnerClasses attribute for an anonymous inner class" when building project

[gdomingues]

After adding this lib to one of the projects I work with I'm facing more than 500 warnings when building the project. It seems it has to do with Log4J as you can see below.

Error:warning: Ignoring InnerClasses attribute for an anonymous inner class
Error:(org.apache.log4j.chainsaw.ControlPanel$1) that doesn't come with an
Error:associated EnclosingMethod attribute. This class was probably produced by a
Error:compiler that did not target the modern .class file format. The recommended
Error:solution is to recompile the class from source, using an up-to-date compiler
Error:and without specifying any "-target" type options. The consequence of ignoring
Error:this warning is that reflective operations on this class will incorrectly
Error:indicate that it is *not* an inner class.

Uber Rides SDK is the only lib I have on my project which has Log4J as a dependency, according to what I see when I run ./gradlew app:dependencies.

I've tried to add these rules to the Proguard file, though it didn't work:

-keepattributes InnerClasses
-keepattributes EnclosingMethod
-dontoptimize

By now I'm removing the Rides SDK from my project, since apparently there's nothing I can do from my side to suppress all these warning messages.

If you need more info, just let me know.

Thanks for the report. We'll look into it!

Please update to the latest SDK "0.5.1" where log4j should not be included, however there is a separate proguard issue.

You should be able to add this to your proguard file to continue for now. We'll be updating the SDK with a fix soon.

-dontwarn com.google.api.**

This is now fixed in v0.5.2

Any update on this issue?

android{
lintOptions {
checkReleaseBuilds false

}*

}

use that above in your gradle and things will go well
