Question

Hello wave slightly smiling face I have a question regarding my android project Recently I just had App1 but now I need to be able to build another apk different package name from the same code base App2 So what I did so far is to split up the app in modules like this com base se app1 se app2 both app1 and app2 depend on base in base i have a file com base Constants kt in app2 I want to override that file So app2 also has file com base Constants kt but with different values When I run both app1 and app2 in debug everything works well But when I am trying to generate a signed apk for app1 and app2 I get error `Duplicate jar entry com base Constants class ` Does anyone know how to deals with this Can I specify in gradle somehow to now include the Constant kt in base Or did I misunderstood how to use modules with multiple apps Thankful for any answers pray pray pray FYI I know that gradle can be used to handle constants but right now I am just using that file to test if this structure of modules is possible

Just move the file base com base Constants kt into app1 com base Constants kt if you only need it in app1

Daniel Garibaldi · Answer

Remove it from constants from base it would probably work but I would suggest to not use a KT for defining constants

Daniel Garibaldi · Answer

For that it s better to use the xmls files in the res folder

Alexandra Tsampikakis · Answer

the module base is using Constants So i can t move it to app1

Unless you re doing some logic in this kt file you should use resources

Alexandra Tsampikakis · Answer

Ignore the constants file it the possibility to override a class that I am looking for slightly smiling face

ribesg · Answer

Well you could use that <https docs gradle org current javadoc org gradle api file DuplicatesStrategy html>

ribesg · Answer

It s a flag you can set on a jar build if you set it to EXCLUDE then it ignores files that are already in the jar That would mean you would need to first add app1 2 files then add base files And in this case base s Constant file would not be added

Alexandra Tsampikakis · Answer

yes < ribesg> that is what I am trying to do like this ``` packagingOptions exclude base src main res java com base Constants kt ``` But I am not sure how to write and I have not succeeded yet

Alexandra Tsampikakis · Answer

do you know how to write the exclude btw the module is not a jar its an android project

Rok Koncina · Answer

If you re using it in the base then you shouldn t override it in the app2 Make 2 separate configs one for the base and one for the app2 if you need to

Alexandra Tsampikakis · Answer

< Rok Koncina> thanks for the answer but I am using the file in the base module and base module does not depend on app2 so I don t see how that could work confused

Rok Koncina · Answer

Consider it from this perspective if it s constants then define them as constants and don t override them If they are configuration then create some configuration holder class in the base module and then set it s values from app1 and app2
