No code generated for schemas located with https: and locally, but http: works.

I believed that

XmlSchemaClassGenerator.Console.exe --verbose --output=gen "https://schemas.opengis.net/gml/3.2.1/gml.xsd"

should generate classes for the opengis gml schema types in the exsisting folder "gen". However what happens is

1. gen stays empty
2. I get a lot of messages about types already been declared:

[...]
The complexType 'http://www.opengis.net/gml/3.2:FeatureArrayPropertyType' has already been declared.
The complexType 'http://www.opengis.net/gml/3.2:BoundedFeatureType' has already been declared.
The complexType 'http://www.opengis.net/gml/3.2:AbstractFeatureCollectionType' has already been declared.
The complexType 'http://www.opengis.net/gml/3.2:FeatureCollectionType' has already been declared.
The complexType 'http://www.opengis.net/gml/3.2:IndirectEntryType' has already been declared.
The complexType 'http://www.opengis.net/gml/3.2:DefinitionProxyType' has already been declared.
The simpleType 'http://www.opengis.net/gml/3.2:IncrementOrder' has already been declared.
The complexType 'http://www.opengis.net/gml/3.2:MovingObjectStatusType' has already been declared.

Next I mirrored the schema and tried the local files:

XmlSchemaClassGenerator.Console.exe -o "out" -v schemas.opengis.net/gml/3.2.1/gml.xsd

And got the same messages as above and no code.

HOWEVER

If I use http: instead of https: to locate the schema:

XmlSchemaClassGenerator.Console.exe --verbose --output=gen "https://schemas.opengis.net/gml/3.2.1/gml.xsd"

The classes are generated, and they compile and work.

I've tried:

• The current xscgen tool in windows and linux
• The current 2.1.1167 release on windows and linux
• A build of HEAD on linux.

What is wrong? Did I miss something? The gml schemas do a lot of mutual XIncludes, which might explain why the tools receives duplicate definition - so I'd guess that some check for recursive XIncludes is kind of broken?

There is a chain of includes that leads to http://schemas.opengis.net/iso/19139/20070417/gco/basicTypes.xsd which has

<xs:import namespace="http://www.opengis.net/gml/3.2" schemaLocation="http://schemas.opengis.net/gml/3.2.1/gml.xsd"/>

The validation in XmlSchemaSet treats this as a different URI than https://schemas.opengis.net/gml/3.2.1/gml.xsd.

Oh wow, thank you! I fixed this for me by using a custom XmlResolver that forces an URL scheme.
