Hi,

Since I updated from Spine 3.6 to 3.7 (3.7.81), I can't export JSON + Atlases from the command line utility.

It fails with this:

/Applications/Spine/Spine.app/Contents/MacOS/Spine -e export-config.json
Spine Launcher 3.7.81
Esoteric Software LLC (C) 2013-2019
Mac OS X x86_64 10.14.1
ERROR: Missing output path.

Following is an example of config file I use:

{
    "project": "/absolute/path/to/skeleton.spine",
    "output": "/absolute/path/to/output/",
    "class": "json",
    "extension": ".json",
    "format": "JSON",
    "nonessential": true,
    "prettyPrint": true,
    "createAtlas": true,
    "texturePacker": {

        "paddingX": 2,
        "paddingY": 2,
        "edgePadding": true,

        "maxHeight": 2048,

        "alphaThreshold": 0,

        "wrapY": "ClampToEdge",
        "format": "RGBA8888",
        "alias": true,
        "outputFormat": "png",
        "jpegQuality": 0.9,
        "ignoreBlankImages": true,
        "fast": false,
        "debug": false,
        "silent": false,
        "combineSubdirectories": false,
        "ignore": false,
        "flattenPaths": false,
        "premultiplyAlpha": false,
        "useIndexes": false,
        "bleed": true,
        "limitMemory": false,
        "grid": false,
        "scale": [ 0.2, 0.4 ],
        "scaleSuffix": [ "@1x", "@2x" ],
        "atlasExtension": ".atlas",
        "name": null
    }
}

This used to work perfectly fine before updating to Spine 3.7, as you can see, there is an output path specified. I tried to add it with -o option on the command line as well but it fails with the same error.

Is there anything I am missing or is this a bug?

As I rely a lot on the command line tools to export animations, this makes Spine 3.7 unusable for me at the moment

Some more information:

The export works with the new Spine launcher (3.7.81) set up to spine 3.6.53, but fails as soon as I set its version to 3.7.81

Thanks!
