i'am new for geoserver souce code,and I've just down load this imagemosaic-stac plugin,and import to geoserver source code,import maven module,and catch many errors which like :"com.joshfix.geotools.geotiff does not exist" in StacMosaicReader.java,and other not found in AoiLayerListener.java、StacRestClient.java、AssertDescriptor.java etc.
And in Maven window,imagemosaic-stac's Dependencies com.joshfix:cog-image-reader:0.0.1-SNAPSHOP download fail,i've try many times to reimport,but all failed, why?i've no idea.
