如何在Buck中使用自定义注释处理器？

Question

As the title states - I'd like use custom Java Annotation Processors with Buck (eg Dagger 1 / 2). Checking out the documentation did not reveal any evident annotation-processing related properties for any Java (or Android) related build rules, and I also couldn't find any examples for this scenario.

I did find this issue thread on GitHub though, without any meaningful recent answers.

Is this something that Buck still does not support? In case not, did anyone find a workaround for this?

Answer 1

Coneko points you to the code in question in that issue. Every build rule in Buck has a Description with an Arg class that describes the arguments the rule takes. In the case of java_library , there is annotation_processor_deps , annotation_pocessor_params , annotation_processors , and annotation_processor_only .

• annotation_processor_deps - the set of dependencies needed to run the annotation processor
• annotation_pocessor_params - the list of arguments to pass to the annotation processors
• annotation_processors - the annotation processors
• annotation_processor_only - True if this library is only an annotation processor
