Fyi @jpobst it looks like the generated binding doesn't compile:

obj\Debug\net6.0-android\generated\src\Org.Gradle.Cli.AbstractCommandLineConverter.cs(11,89): error CS0535: 'AbstractCommandLineConverter' does not implement interface member 'ICommandLineConverter.Convert(ParsedCommandLine, Object)'
obj\Debug\net6.0-android\generated\src\Org.Gradle.Wrapper.Download.cs(10,60): error CS0535: 'Download' does not implement interface member 'IDownload.Download(URI, File)' 

It may be a general binding behavior change moving from Xamarin to .NET 6+.

@ivmazurenko can you attach a .binlog of a Rebuild, it skipped this part:

Skipping target "GenerateBindings" because all output files are up-to-date with respect to the input files.

There are some changes to defaults between classic and .NET 6 projects that might be affecting some metadata changes you previously did. You can try setting them back to their classic values to see if it helps.
