this submodule name is test with build.kts file contains

configurations.create("default")
artifacts {
  add("default", files("1st.aar"))
  add("default", file("2nd.aar"))
}

trying to add this 2 .aar files in submodules then this submodule is added in another core module like this

implementation(project(":test"))

but the only 1.aar files can be inflated in the core module why the other '2.arr' file data is not coming in that core module can anyone help here.

Sounds very unlikely that this is specific to the Kotlin DSL, so the question is actually off-topic here. Besides that, is it maybe because you use

files

in the first line but

file

in the second? 🤷‍♂️ Here is the official docs on how to properly share things between projects: https://docs.gradle.org/current/userguide/cross_project_publications.html

I want to use both the aar files @Vampire but in doc there is nothing how can I use both the aar files

Can you knit an MCVE?

Adding 2 aar files like this not able use functions of both the file. only one is getting called

If this should be the MCVE, it neither is C nor V ;-)
