Why does Gradle build fail with "Unable to merge dex" error after adding SegementProgressBar library?

Hello,

After adding your library to my app's build.gradle, I get the following error message:

Error:Execution failed for task ':app:transformDexArchiveWithExternalLibsDexMergerForDebug'. com.android.builder.dexing.DexArchiveMergerException: Unable to merge dex

From what I can gather, this indicates that there is some kind of dependency issue. I tried resolving the issue by updating my google-services dependencies and updating android sdk to no avail. Furthermore, I am not using Kotlin to develop my application.

Is there a way to find which dependency might be causing this, if any?

Thanks a lot for your time!

Below I have posted my project build.gradle and my app build.gradle and information related to Android Studio version and JVM version.

Project build.gradle

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.0.0'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
        mavenCentral()
        maven {
            url "https://jitpack.io"
        }
    }
}

    delete rootProject.buildDir
