Extract com.mysema.query.types as module to minimize deps of generated code #103

At the moment generated code (Q... classes) contains imports to com.mysema.query.types. This package is in querydsl-core module/jar which has a lot of dependencies (see querydsl / querydsl-core / pom.xml).

Now imagine a value module which provides types with @embeddable annotations. It would be good if this simple module could have a minimized set of RUNTIME thirdparty deps e.g. a querdsl-core-types module.

What do you think?

Sincerely, h2000

PS. Thank you very much for your great library!

This might make sense if the generated query types would primarily be used without Querydsl queries. Is it like that in your case? Could you present your case in more detail?

h2000 commented Feb 25, 2012

Generally I would try to minimize deps where possible (esp. coming from a big osgi project). Try to reverse your view: why should the generated project depended on such "big" jar esp. if the imports in the generated code success otherwise.

We have a relative simple module with embeddable value classes like money (currency+big decimal amount). So why should we add so much third-party deps to the module? It is possible that the user of the module did not want to use the querydsl at all, so the price using our module should be so small as possible.

I think this could be a good starting point to minimize other module deps as well.

We can't make such a change for a minor release, but this can be considered for 2.4.0 or 2.5.0.

This issue is related : #106

In addition to ripping codegen related classes also the alias functionality could be extracted. Then the cglib dependency could be dropped.

Querydsl core should be now quite minimal :

Bundle-SymbolicName: com.mysema.querydsl.core
Bundle-Name: Querydsl Core
Bundle-Vendor: Mysema
Bundle-ManifestVersion: 2
