[ERROR] Failed to execute goal on project dhis-api: Could not resolve dependencies for project org.hisp.dhis:dhis-api:jar:2.35-SNAPSHOT: The following artifacts could not be resolved: org.geotools:gt-opengis:jar:18.0, org.geotools:gt-geojson:jar:18.0: Could not find artifact org.geotools:gt-opengis:jar:18.0 in MavenCentral (https://repo1.maven.org/maven2)

I tried to set the opengis jarfile manually but still the issue is not resolved. Please help me to set-up build and run the dhis2 project successfully , so that I can run it on my own server.
Thanks
