Cannot read amazfit gpx track

[Nymerea]

Hi, I cannot parse a gpx file imported from my amazfit watch. java.io.InvalidObjectException: Invalid GPX: Invalid value for 'version': Unknown version string: '7.7.5-play'.

here is an exemple of the gpx file :

<?xml version='1.0' encoding='UTF-8' standalone='yes' ?>
<gpx xsi:schemaLocation="http://www.topografix.com/GPX/1/1 http://www.topografix.com/GPX/1/1/gpx.xsd" xmlns="http://www.topografix.com/GPX/1/1" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:ns3="http://www.garmin.com/xmlschemas/TrackPointExtension/v1" xmlns:ns2="http://www.garmin.com/xmlschemas/GpxExtensions/v3" xmlns:ns1="http://www.cluetrust.com/XML/GPXDATA/1/0" creator="Zepp App" version="7.7.5-play">

The version attribute determines the GPX version, which is either "1.0" or "1.1", according to the GPX-standard. The amazfit watch is creating an invalid GPX file.

You have to fix the version string to "1.1".

[Nymerea]

In this code

    public static Version of(final String version) {
            return switch (version) {
                case "1.0" -> V10;
                case "1.1" -> V11;
                default -> throw new IllegalArgumentException(format(
                    "Unknown version string: '%s'.", version
                ));
            };
        }

can't we make it return V11 by default ?

Since the given GPX file is invalid, this is not my preferred fix. But I can imagine, that such files are readable with lenient mode.

final var gpx = GPX.Reader
    .of(Mode.LENIENT)
    .read("invalid.gpx");

Merged into r3.1.0.

Thanks a million for the fix. I had to write my own parser with xstream. I will happilly migrate to jpx :-)
