Where should I put IDL files and generated code in Maven project?

I use standard Maven directory structure for my project

- src
  - main
    - java
    - resources
    - webapp
  - test
    - java
    - resources

- target

Now I want to use Thrift and gRPC but I don't know where should I put IDL files and where to put generated code? Is there any "standard" or "best practices" suggestion? Thank you for help!

Solution

you put the AIDL files in the 'exact' same package as you want your generated files to be (with respect to package), You put the AIDL files in your src/ tree and the 'generated' files will be in the 'generated' tree.

src
- main
  - java
    - org
      - whatever
        
        project
        
        services
        
        aidl
        
        POJO2.java
        
        IRemoteService.aidl
        
        IRemoteServiceCallback.aidl
        
        POJO1.aidl

By doing this, the generated files will be in the 'org.whatever.project.services.aidl' package

Here is a good guide. http://developer.android.com/guide/components/aidl.html
