"Error while processing" errors in BindingsGenerator task of ExportJarToXml target.

[awattar]

Steps to Reproduce

I'm getting a few message errors that are not causing bindings build as failed:

Error while processing '[Method] java.time.temporal.Temporal adjustInto(java.time.temporal.Temporal temporal, long newValue)' in '[Class] java.time.temporal.ChronoField': Type 'java.time.temporal.Temporal' was not found.
Error while processing '[Method] java.time.temporal.Temporal addTo(java.time.temporal.Temporal temporal, long amount)' in '[Class] java.time.temporal.ChronoUnit': Type 'java.time.temporal.Temporal' was not found.
Error while processing type '[Class] X': Type 'Y' was not found.

Those errors are probably only related to ExportJarToXml phase because those errors are not travelling to the GenerateBindings target. It cannot be adjusted by transforms as ExportJarToXml/BindingsGenerator TransformFiles property is empty.

It seems that BindingsGenerator behaves differently for those two targets - probably to OnlyRunXmlAdjuster property true/false difference.

Expected Behavior

Build without error messages.

Actual Behavior

Error messages present.

There is some information on this error here: https://stackoverflow.com/questions/51128130/xamarin-android-binding-generation-giving-type-x-was-not-found-errors-for-clas

Sounds like you can try adding <AndroidEnableDesugar>true</AndroidEnableDesugar> or <AndroidDexTool>dx</AndroidDexTool> to your .csproj and see if that helps.

If not, is the library you are trying to bind public? Can you provide it or your MSBuild log for us to look at? (Getting diagnostic log)

Closing due to lack of info. If you are still encountering this and can provide a log, feel free to re-open.

I am trying to create a Xamarin Binding Library from an .aar. I created a simple android studio project with a one simple activity and build .aar file. After it go to rider with jetbrains xamarin sdk version 11.2.0.21 and create an empty Binding library and add my .aar with LibraryProjectZip as build action. Also add .aar dependencies and compile it. Into debug console I get this error:

Error while processing '[Method] java.time.temporal.Temporal adjustInto(java.time.temporal.Temporal temporal, long newValue)' in '[Class] java.time.temporal.ChronoField': Type 'java.time.temporal.Temporal' was not found.

Error while processing '[Method] java.time.temporal.Temporal addTo(java.time.temporal.Temporal temporal, long amount)' in '[Class] java.time.temporal.ChronoUnit': Type 'java.time.temporal.Temporal' was not found.

I added to my .csproj this line to enable java 8 features, but does not work.

NOTES:

• I share a simple project for it
  https://github.com/estebanhiguitad/XamarinBindingApplication

• I need support those API versions in my project, from 21 to 30.

• I share this issue to rider team, leave link:
