Re: [tycho-user] tycho demo "itp01" with maven build not working


Maven 3.6.1 and 3.6.2 do not work with tycho. Can't remember nature of regressions, but this is likely cause. Either downgrade to 3.6.0 or upgrade to 3.6.3.

My question: is this example running for you, or am I doing anything wrong? Any help on getting this work would be appreciated!
Locally I have installed maven 3.6.1:

$ mvn --version
