Can't run java project with tdlib

[ArtoLord]

I am trying to build a project with tdlib but getting an error:

[ 1][t 0][1572598921.344264507][tl_jni_object.cpp:37]	Can't find class [org/drinkless/tdlib/Client]

What am I doing wrong?

The class org/drinkless/tdlib/Client is unknown to JVM. It is likely that it wasn't built during project build phase.

What can i do to build project with this class?

Usually, just add to the project. You have already did this, so you need to investigate why it is not available. You can also look at https://github.com/whyoleg/ktd as an example of TDLib usage from Kotlin.
