More than one file was found with OS independent path 'org/apache/commons/csv/QuoteMode.java'

Question

As far as I have read the other link regarding similar issues like this, there is always the issue of 2 libraries conflicting, I think that's the case with me too but can anyone tell me which library is causing the conflict or what is the issue and how do I resolve this issue? Below is my Gradle, and I only get this one line error in my stack trace. Any help would be appreciated. This error only comes when I run any instrumented test in this package, I have other packages as libraries, and all of those tests run fine, but I can't run any instrumented test in this package.

apply plugin: 'com.android.library'

android {
    compileSdkVersion rootProject.ext.compileSdkVersion


defaultConfig {
    minSdkVersion rootProject.ext.minSdkVersion
    targetSdkVersion rootProject.ext.targetSdkVersion

    versionCode rootProject.ext.versionCode
    versionName rootProject.ext.versionName

    testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    consumerProguardFiles 'consumer-rules.pro'
}

buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
    }
}
testOptions {
    unitTests.returnDefaultValues = true
}
compileOptions {
    sourceCompatibility = 1.8
    targetCompatibility = 1.8
}

}

I read alot of ther links similar to this error, but I couldn't not find a solution for me, but it didn't cross my mind to check for these too lines. first:

check if you have set this in you build.gradle->dependencies

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

if you've set this in you build.gradle file then check for this too if you tried to import libraries from your libs directory:

implementation files('libs/...')

if you have this too in your build.gradle file, please remove it or comment it out, because you are trying to re-import the library again which result is that error.
