  • development environment/workspace, best practices for setting up?
  • build infrastructure
    • Buckminster vs. Tycho/Maven
    • how to create a new build job for my Palladio Addon?

Best practice Developer On-Boarding (question from fortiss)

  • Falix: development environment, best practices how to setting up?
    • Philipp: when doing refactoring, use buckminster to materialize all plugins; otherwise, install nightly into Eclipse, check out only plug-ins to be changed
    • Steffen: recommends his students to use Eclipse's materialize wizard for any slightly larger project
  • Felix: we do have error messages when trying to materialize
    • Christian: solution to current problem
      • cause: you try to materialize the target platform, which however points to local directory on the build server
      • recommendation: don't materialize target platform, just download modelling tools Eclipse
  • Philipp: EventSim is so far decoupled from integrated Palladio build; rmap files refer to nightly build rather than cmap files as often as possible
    • don't know if materialization works as intended
    • needs to be "fixed" before EventSim can be integrated into the release
  • Steffen: by the way, Wiki build documentation is still in progress, planned to be completed soon

Build Infrastructure

  • Felix: did you consider using Vagrant?
    • Steffen: thinking of offering master thesis
  • Steffen: or use Tycho?
    • Stephan: parent POM required, no POMs on a per-plugin-base required
    • Steffen: Tycho better maintained than Buckminster, but migration overhead considerable
    • Stephan: stepwise migration should be possible
      • Solution 1: generate update sites via Tycho, include update site in Buckminster
      • Christian, Solution 2: maven (repository) reader in Buckminster
      • Steffen: other direction works as well (read buckminster builds from maven)
  • Stephan: we should systematically compare features Buckminster vs. Maven
    • Steffen: likes materialization feature into workspace
