Retrofit2 and baseurl in GitLap - retrofit2

Question

I am trying to learn retrofit2 by showing my project's GitLab name into recyclerView . but I can not find what is exactly what to do!!!
according gitlab wiki I found private-tokens and list of projrct.
this is my baseUrl and I create a builder:
Retrofit.Builder builder = new Retrofit.Builder()
.baseUrl("https://gitlab.com/api/v4/projects?private_token=xxxxxx")
.addConverterFactory(GsonConverterFactory.create());
and this is my endpoint:
#GET("/users/:{userid}/projects")
Call<List<GitLabRepo>> reposForUser(#Path("userid") int user);
my GitLabRepo pojo class:
class GitLabRepo {
private String name;
public String getName() {
return name;
}
}
after running I got this error:
java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.sayres.createandroidclient/com.example.sayres.createandroidclient.MainActivity}: java.lang.IllegalArgumentException: baseUrl must end in /: https://gitlab.com/api/v4/projects?private_token=rjezfrSUTn3fcugxLujm/

I know my problem is related to baseUrl but what is correct gitLab BaseUrl?
I want just show my project name into list at recycelerview list.
******************Edit******************
I use of poster :
https://gitlab.com/api/v4/projects?private_token=******/users/:******/projects
And I got :
{
"message": "401 Unauthorized"
}
I see into Status codes at gitlab wiki and wrote there:
401 Unauthorized The user is not authenticated, a valid user token is necessary.
but I have added Private Tokens .

remove the forward slash '/' from get i.e,change your code like this
#GET("users/:{userid}/projects/")
Call<List<GitLabRepo>> reposForUser(#Path("userid") int user);
and add '/' in your endpoint like this
Retrofit.Builder builder = new Retrofit.Builder()
.baseUrl("https://gitlab.com/api/v4/projects?private_token=xxxxxx/")
.addConverterFactory(GsonConverterFactory.create());
