As Mike pointed out, those errors are reported by the Eclipse maven tooling. In the POM editor there are some quick fix options you can use to convince Eclipse to ignore build plugins it doesn't understand.
If what you want to do in Eclipse is work on the Guacamole java code, you'll probably be able to work just fine by first running 'mvn package' outside of Eclipse to do the parts that aren't handled by the Eclipse build. carl > On Feb 7, 2018, at 6:34 PM, Mike Jumper <mike.jum...@guac-dev.org> wrote: > >> On Wed, Feb 7, 2018 at 1:26 PM, Cyxo Pykob <cy...@yahoo.com.invalid> wrote: >> >> Hello Guacamole team, >> I am trying to build Guacamole client using Eclipse IDE.
