Add commons-io dependency to gradle project in Android Studio

Question

Very simple question - how to add commons-io dependency to gradle Android project?

I tried the following

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.5.+'
    }
}

apply plugin: 'android'

dependencies {
    compile files('libs/android-support-v4.jar')
    compile group: 'commons-io', name: 'commons-io', version: '2.0.1'
}

but it does not work The error is

Gradle: A problem occurred configuring project ':LearnIt'.

Failed to notify project evaluation listener. Could not resolve all dependencies for configuration ':LearnIt:_DebugCompile'. > Could not find commons-io:commons-io:2.0.1. Required by: learnit:LearnIt:unspecified

In case anyone needs all apache commons libs - http://mvnrepository.com/artifact/org.apache.commons — Jaydev, May 10 '17 at 13:22

As of now (May 2014) if you use the default generated project it is actually amazingly simple (though difficult to find instructions!

Open the second level build.gradle, and add the following line to the dependencies {:

compile "commons-io:commons-io:+"

That will get the latest version of commons-io. My complete file looks like this:

apply plugin: 'android'

android {
    compileSdkVersion 19
    buildToolsVersion "19.0.0"

    defaultConfig {
        minSdkVersion 18
        targetSdkVersion 19
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            runProguard false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
        }
    }
}

dependencies {
    compile "commons-io:commons-io:+"
}

That works great - very useful to have IOUtils as part of the project. – MikeV Oct 28 '14 at 21:58

Thanks for this but do not use + operator in dependencies. that is bad for version differences. – okarakose Apr 09 '16 at 20:45
It has pros and cons. – Timmmm Apr 09 '16 at 20:50

@OmerKarakose is right. It is better to stick to one version and not pull the latest always. – Dinesh Oct 23 '16 at 21:15

you need to declare a repository where you want to resolve the commons-io library from (e.g. MavenCentral):

buildscript {
    repositories {
        mavenCentral()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:0.5.+'
    }
}

apply plugin: 'android'

repositories{
    mavenCentral()
}

dependencies {
    compile files('libs/android-support-v4.jar')

    compile group: 'commons-io', name: 'commons-io', version: '2.0.1'
}

see buildscript { repositories { mavenCentral() } – Georgy Buranov Jul 27 '13 at 11:15

You have it configured inside `buildScript`, but not inside the build file itself. `buildScript` is used to declare additional dependencies needed by the custom tasks themselves, and not dependencies needed by the project being built. Also note that Rene is a gradle committer. He knows what he's talking about. See http://www.gradle.org/docs/current/userguide/organizing_build_logic.html#sec:external_dependencies – JB Nizet Jul 27 '13 at 11:27
ok thank you! Now it is clear, but was a little bit confusing at the beginning – Georgy Buranov Jul 27 '13 at 13:24
I am keep getting this error : Unable to load class 'org.apache.commons.io.FileUtils'. Android Studio 3.2.1 – sobby01 Dec 16 '18 at 12:54
Something like this would work these days as well: implementation "commons-io:commons-io:2.4" – ror Jul 29 '20 at 13:11

Use gradlePlease to get the dependency.

Add the following to your app/build.gradle file:

dependencies {
    compile 'org.apache.commons:commons-io:1.3.2'
}

//UPDATED

implementation group: 'commons-io', name: 'commons-io', version: '2.6'
