Импорт библиотеки GraphStream в Android Studio

Я импортировал модули gs-ui-android и gs-core-2.0-alpha, и они также отражены в settings.gradle. Также включены в модуль приложения Gradle

implementation files(':gs-ui-android')
implementation files(':gs-core-2.0-alpha')

Также включены операторы импорта

 import org.graphstream.graph.*;
    import org.graphstream.graph.implementations.*;

Я все еще получаю ошибку в этом коде

error: package org.graphstream.graph does not exist error: package org.graphstream.graph.implementations does not exist error: cannot find symbol class SingleGraph error: incompatible types: String cannot be converted to Node error: cannot find symbol class Viewer

Пример кода:

Graph graph1 = new SingleGraph("I can see dead pixels");
    graph1.addNode("A" );
    graph1.addNode("B" );
    graph1.addNode("C" );
    graph1.addEdge("AB", "A", "B");
    graph1.addEdge("BC", "B", "C");
    graph1.addEdge("CA", "C", "A");
    Viewer viewer = graph1.display();

Build.gradle (модуль приложения):

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
