How to properly connect the Android Studio module?

Question

Android

I am developing an application, one of the functions of which is the identification of a person by voice. I found a project on the Internet that implements the necessary functionality.
I had to update Gradle to the latest version to get it to work. It starts up and works fine.

I tried to integrate marffull into my project.

Here are my gradle files:
project build

// Top-level build file where you can add configuration options common to all sub-projects/modules.
plugins {
    id 'com.android.application' version '7.1.2' apply false
    id 'com.android.library' version '7.1.2' apply false
    id 'org.jetbrains.kotlin.android' version '1.5.30' apply false
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

build module app:

plugins {
    id 'com.android.application'
    id 'org.jetbrains.kotlin.android'
}

android {
    compileSdk 32

    defaultConfig {
        applicationId "com.example.tes5skyrimreal"
        minSdk 28
        targetSdk 32
        versionCode 1
        versionName "1.0"

        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
    kotlinOptions {
        jvmTarget = '1.8'
    }
}

dependencies {

    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'androidx.core:core-ktx:1.7.0'
    implementation 'androidx.appcompat:appcompat:1.4.1'
    implementation 'com.google.android.material:material:1.5.0'
    implementation 'androidx.constraintlayout:constraintlayout:2.1.3'

    implementation project(path: ':marffull')

    testImplementation 'junit:junit:4.13.2'
    androidTestImplementation 'androidx.test.ext:junit:1.1.3'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.4.0'
}

settings:

pluginManagement {
    repositories {
        gradlePluginPortal()
        google()
        mavenCentral()
    }
}
dependencyResolutionManagement {
    repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
    repositories {
        google()
        mavenCentral()
    }
}
rootProject.name = "TES 5 SKYRIM REAL"
include ':app', ":marffull"

The problem is that the studio stubbornly does not recognize some java files.
What is recognized:

import marf.MARF
import marf.Storage.ModuleParams
import marf.Storage.TrainingSet
import marf.util.MARFException

What is not recognized:

import marf.util.Debug
import marf.util.OptionProcessor

It all looks rather strange. In marf.Storage, I can get some files, but not all. In marf.util I can only get exceptions, not class files.
