[Solved]-How to resolve 'Offline / Missing artifact org.geotools:gt-shapefile:jar:17-SNAPSHOT' in Maven?-eclipse

i think that instead of ${geotools.version} you should place a real version number of the project, like 15.1 i am not sure though if that's the problem

also, you might want to consider changing to gradle build. i think it is a lot simpler

it looks like the boundless artifactory was down at that moment. for the time being you can use version 16-rc1 as the latest released version, 15.2 as the last stable release.

if you absolutely must be on the cutting edge, i'd recommend downloading/cloning master and building it locally.
