Hi Henrik, hello builder,

Can you provide some more information about this builder job? What did

Hi Sebastian,

Short answer - the builder that was executed was just test code - it
returned a fixed build result (a .txt file).

Longer answer - B3 has the notion of BuildUnit (the thing you are
building), and Builder the thing that operates on a BuildUnit to produce
some result.
A Builder is an asynchronous function with declarative dependencies on
other Builders (i.e. other build results from other BuildUnits).
When calling a Builder, it returns an Eclipse Job. When this job is run,
it collects the result of all the declarative dependencies and executes
its specific build step.

My first run (using a toy example) managed to run one of these builders.

Here is (part of) the toy model in b3 DSL:

unit fruitsallad version 1.0.0 {
builder make {
input {
unit/apple/1.0.0#dice;
unit/banana/1.0.0#dice;
unit/orange/1.0.0#dice;
}
}
}

unit apple version 1.0.0 implements Fruit {
builder peel {
output { applepeel.txt; }
}
builder seeds {
output { appleseeds.txt; }
}
builder pulp {
output { applepulp.txt; }
}
}

Will write a lot more about how this all works once I have it working...
