Retrofit : Url is being changed

Question

Currently I am facing some issues with Retrofit. The URL, I am providing to RetrofitInstance is changing for the second request. Here are the codes:

object RetrofitClientInstance{

     private var retrofit: Retrofit? = null
     //private const val BASE_URL = "http://api.sample.com/req/";
     private const val BASE_URL = "http://test.sample.com/req/"
     private const val BASE_URL_VERSION = "v1/"


     fun getRetrofitInstance() : Retrofit {
        if (retrofit == null) {
            retrofit = Retrofit.Builder()
                    .baseUrl(BASE_URL + BASE_URL_VERSION)
                    .addConverterFactory(GsonConverterFactory.create())
                    .build()
        }
        return this!!.retrofit!!
    }

}

Here are the interface methods for different API requests:

class UserLoginResponseReceiver{

    interface GetDataService {

        @FormUrlEncoded
        @POST(UrlEndPoints.USER_LOGIN_BY_FACEBOOK)
        fun loginUserByFacebook(@Field("access_token") last: String): Call<FbLoginResponse>

        @GET(UrlEndPoints.ALL_POSTS)
        fun getAllPosts() : Call<AllPostsResponse>

    }
}

UrlEndPoints.kt

object UrlEndPoints {

   const val USER_LOGIN_BY_FACEBOOK = "user/auth/facebook"
   const val ALL_POSTS = "post"
}

For the first request (loginUserByFacebook), the URL I am getting by debugging my response is:

http://test.sample.com/req/v1/user/auth/facebook

Which is fine and working perfectly. But for the second request (getAllPosts()) I am getting the following URL:

http://test.sample.com/post

The "req/v1" part is completely cut off! As a result I don't get the desired response. What's the problem here actually? Please help me.

I can't reproduce this, you should try cleaning / rebuilding your project, the code you've provided here has no errors in it.

This is the code I added to test it:

class AllPostsResponse
class FbLoginResponse

fun main(args: Array<String>) {
    val service = RetrofitClientInstance.getRetrofitInstance()
                     .create(UserLoginResponseReceiver.GetDataService::class.java)
    val url = service.getAllPosts().request().url()
    println(url)
}

The URL returned here is the following, as expected:

http://test.sample.com/req/v1/post
