Oracle ojdbc8 12.2.0.1 Forbidden by Maven since December 2017, before that worked well. What configuration has changed on the Oracle repository (setting.xml)?
Maven project: https://github.com/sgrillon14/MavenSampleOracleJdbc
Full trace: https://travis-ci.org/sgrillon14/MavenSampleOracleJdbc
It's possible that the Oracle Maven terms have changed. You may need to re-register on the Oracle Maven site: http://www.oracle.com/webapps/maven/register/license.html I tried your github script and it worked fine with me:
$ mvn clean install --settings test/mvnsettings.xml
