In execute_codegen, line 130 the target_classpath does not contain what I want, i.e it contains scala std libs but not the target dependencies like the hibernate library in the following setup :

querydsl_library(
    name='meta-model',
    dependencies=[
        'libs/hibernate/src/main/scala',
    ],
    sources=rglobs('*.java'),
)

I'm still confused with how pants exactly works
