Minutes

• Java 8 issues with Oxygen
  • Running development launch configurations requires Java 8
  • VIATRA will still target Java 7
    • Requiring Java 8 would not work before Luna
  • TODO Zoli: create issue
• Maven toolchain setup
  • Code generation’s target Java version can differ from Maven’s Java version
• DSE Maven support
  • DSE plugins as pure Maven modules
  • Would be good for TTC model generation
  • WIP
• Model transformation debugger status
  • Demo: Current status of prototype
  • Java debugger - VIATRA debugger interoperability: when execution is suspended on a Java breakpoint in a transformation’s “right side”:
    • the Variables and Debug view shows Java content
    • Java stepping etc. can be used
    • modifications performed by the Java code during the execution of the right side won’t be displayed in the Transformation Model Instance Viewer, only the latest state before the activation
    • when resuming, execution can be suspended again on a VIATRA breakpoint
  • TODO Peti: documentation on wiki
  • TODO a transformation developer?: test whether more features are needed
