Re: [tycho-user] [CAUTION] Tycho fetches dependency information from Mav

["Sievers, Jan" <jan.sievers@xxxxxxx>]

this is probably caused by

https://bugs.eclipse.org/bugs/show_bug.cgi?id=510198

looks like official maven central JDT core binaries drag in a lot of dependencies which are not needed (at least not for our headless compiler usecase)

I opened

    Hi,
     
    when switching to Tycho 1.2.0 I noticed that during build Eclipse content is fetched from Maven central (trace below), despite my target definition. Is this due to
    https://bugs.eclipse.org/bugs/show_bug.cgi?id=510198? I’d like to understand the background. Are the Eclipse parts which my plugins are compiled against are being fetched from Maven central?
     If not, what are these downloads needed for?
     
    These downloads don’t happen with Tycho 1.1.0.
     
    Build command: mvn clean compile -U
     
    Thanks
