Re: [m2e-users] Programmatically Build Maven Project

[Igor Fedorenko <igor@xxxxxxxxxxxxxx>]

What are you trying to achieve?

m2eclipse-tycho configurators are not expected to do anything during
maven build... actually, project configurators in general are not
expected to do anything during Maven build.

m2eclipse-tycho configurators are only expected to setup PDE natures and
classpath but everything else is delegated to PDE.
