Gradle plug-in doesn't seem to acknowledge all modelConverterClasses

In my build.gradle I have a resolve block similar to:

resolve {
    outputFileName = 'swagger'
    outputFormat = 'JSON'
    prettyPrint = 'TRUE'
    classpath = sourceSets.main.runtimeClasspath
    resourcePackages = ['foo.bar']
    modelConverterClasses = ['foo.bar.Resolver1']
    outputDir = file('/dev/null')
}

My assumption (based on an example I see here: https://github.com/swagger-api/swagger-core/issues/3388) was that converter classes could be chained and had intended to add something like:

modelConverterClasses = ['foo.bar.Resolver1', 'foo.bar.Resolver2']

to my config, where foo.bar.Resolver1 would call the next converter in the chain, presumably Resolver2, however it seems like (via printlns) only Resolver2 is ever called.

Reproduce the behavior from the build.gradle resolve block, using two entries in modelConverterClasses and printlns in Resolver1 and Resolver2. Inspect the Gradle plug-in path that processes modelConverterClasses and verify whether both converters are invoked in the expected chain. Done means the handling is corrected or the supported chaining behavior is made explicit.
