Type com.novi.serde.ArrayLen is defined multiple times

[wxcaixiaowei]

Hi, I encountered the same problem as #109 . When I was building the release package, it kept failing:
Type com.novi.serde.ArrayLen is defined multiple times: /Users/ontwang/.gradle/caches/transforms-3/0fce63b0b50a8e8efde10c93f35c117f/transformed/jetified-client-sdk-java-1.0.5.jar:com/novi/serde/ArrayLen.class, /Users/ontwang/Documents/xxx/xxxxx/ji_app/platform/android/bloc/build/intermediates/runtime_library_classes_jar/release/classes.jar:com/novi/serde/ArrayLen.class

I tried to get the latest example from crux master. After modifying the build.grale, it still didn’t work with same error. And My global dependencies were also removed from diem. These attempts took me a whole day. I want to know why I still get this error when novi is no longer in my dependency tree.

and i try to modify bindGen for cargo build -r bloc && \ , not work

and i try to delete anything of diem ,it take error :

and i try to add

packagingOptions {
exclude 'com/novi/serde/*'
}

still not work ....

Looking forward reply, thanks

Read #108 again and confirm that the solution is probably to remove the reference of diem, and then modify the missing class reference in another way. This will take much time. I think the best way is to update this part of the function in crux

Hey @wxcaixiaowei thanks for raising this. I did notice that the cat_facts example still had a couple of references to the diem deps, which I've now removed and pushed to master. You shouldn't need any external dependencies now, as they are all provided as part of the typesGen task in the shared build.gradle. To include them make sure that the sourceSets are correct. In the examples we have it like this:

    sourceSets {
        main.java.srcDirs += "${projectDir}/../../shared_types/generated/java"
    }

and I noticed you have an extra ../ in yours. Check that it resolves to the correct directory.

LMK if you're still having problems. Happy to work with you until they are resolved (and the feedback is very useful).

Thanks for your reply.

additional ../ is depends on my project directory, because this project is shared by Android and iOS, we all feel that the location of your rust code is not in line with our habits, so we changed the location independently in the project directory, i think it's not a problem. because in debug flavor works.

in fact, I have tried the reference method without adding any diem, but my confusion R8 task will report an error, the specific error path:

Now it is getting closer to the release time of my project, I have to use cargo build -r to package my rust code, manually place the so file under the jnilibs of the project, and then minify enabled false to make my generate signed apk work

So my question is how to make my proguard task not report an error without relying on diem. Thanks again for your reply,Looking forward to your reply again if you can help me
