commons-logging defines classes that conflict with classes now provided by Android after Android Studio Update

Question

I have updated Android Studio to version 3 and now seems unable to compile my project previously compiled without errors.

The error message is the follow

Error:Error: commons-logging defines classes that conflict with classes now provided by Android. Solutions include finding newer versions or alternative libraries that don't have the same problem (for example, for httpclient use HttpUrlConnection or okhttp instead), or repackaging the library using something like jarjar. [DuplicatePlatformClasses]

The dependencies are

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:27.0.0'
    compile 'com.android.support:design:27.0.0'
    compile 'com.google.api-client:google-api-client-android:1.23.0' exclude module: 'httpclient'
    compile 'com.google.http-client:google-http-client-gson:1.23.0' exclude module: 'httpclient'
    compile 'com.google.firebase:firebase-core:11.4.2'
}

and error seems caused by

compile 'com.google.api-client:google-api-client-android:1.23.0' exclude module: 'httpclient'
compile 'com.google.http-client:google-http-client-gson:1.23.0' exclude module: 'httpclient'

I already use exclude module: 'httpclient' So why It doesn't compile? Is this a bug of Android Studio 3 and\or included com.android.tools.build:gradle:3.0.0 plugin or I'm missing something? With the previous version no problem to compile exactly the same project.

Solution 1

Add to build.gradle located in app module

configurations {
    all {
        exclude module: 'httpclient'
    }
}

Solution 2

If the problem is with commons-logging then it must be excluded too. Add the following code in app/build.gradle

configurations {
    all {
        exclude module: 'httpclient'
        exclude module: 'commons-logging'
    }
}

Solution 3

Got the same issue. I have done below changes

 configurations {
    all{
        exclude group: 'commons-logging', module: 'commons-logging'
        exclude group: 'org.apache.httpcomponents'
    }
}


packagingOptions {
    exclude 'META-INF/LICENSE.txt'
    exclude 'META-INF/LICENSE'
    exclude 'META-INF/NOTICE.txt'
    exclude 'META-INF/NOTICE'
    exclude 'org/apache/http/version.properties'
    exclude 'org/apache/http/client/version.properties'
}

Solution 4

You should replace "compile" with "implementation" as it's deprecated in the latest gradle and exlude "org.apache.httpcomponents" from Google api client libraries:

implementation('com.google.api-client:google-api-client-android:1.23.0') {
    exclude group: 'org.apache.httpcomponents'
}
implementation('com.google.http-client:google-http-client-gson:1.23.0') {
    exclude group: 'org.apache.httpcomponents'
}

this solution was found here: https://developers.google.com/google-apps/activity/v1/quickstart/android

Solution 5

Run in terminal, inside project folder:

./gradlew app:dependencies > dependencies.txt

Then check dependencies.txt to find who is using conflictive dependencies and act accordingly (check for updates, get rid of it, or use exclude as suggested by @Silverstorm)

[CommonsWare]

"So why It doesn't compile?" -- your problem is with commons-logging, based on the error. Perhaps there are newer versions of those com.google dependencies that you should be using.

[AndreaF]

@CommonsWareI haven't find any newer library these versions are latest October 2017 releases

[Gabriele Mariotti]

Do you have same jars in libs folder?

[AndreaF]

@GabrieleMariotti absolutely not. I haven't any jars in libs folder. The libraries are only specified in dependencies section in build.gradle (otherwise also the previous Android studio would have refused to build). For this reason I cannot figure why after Android Studio update won't compile.

[Ramesh sambu]

I am not able to get release apk if exclude httpclient

[Silverstorm]

@RameshSambu Have you placed the above code in the inner build.gradle of the app module?

[Ramesh sambu]

Yes I added like that

[scionoftech]

you can find release apk at app/release

[Pkmmte]

You have just saved me from a major release crisis. Thank you!

[Vahe Gharibyan]

compile: compile library for each which contain current module. implementation: compile library for current module, that's mean implemented library not visible for "parent" modules

[Narendra Singh]

In which tag, do I need to put that?

[Silverstorm]

@NerendraJi in configurations. If It's missing just copy paste the code that I have posted.

[Stevey]

What if I'm using httpclient? My code used to compile before upgrading to Android Studio 3.0. I'm actually using httpclient in my code, and I don't want to switch to okhttp.

[Pravinsingh Waghela]

@user3562927 I am also facing and having the same issue as you are having. Did You got any solution for it, as in older version it was working. but after upggading Android Studio and Gradle it is not.

[gbansal]

configurations { all { exclude module: 'httpclient' exclude module: 'commons-logging' exclude group: 'org.json', module: 'json' exclude group: 'org.apache.httpcomponents' exclude module: 'opengl-api' exclude module: 'xmlParserAPIs' exclude module: 'xpp3' } } this works for me

[ARLabs]

Ok, but how libraries that use httpclient would work without it? LVL library of Google depends on org.apache.http

[khammami]

but compile is deprecated in the new Android Studio so you'll get a warning to replace it with "implementation" or " api' & that depends on your need

[kibitzerCZ]

@ARLabs @user3562927 @Pravinsingh-Waghela You need to provide some different httpclient library/wrapper. You could try this one - I was in the same situation yesterday and this library is the only solution that worked for me. You will only have to change all org.apache.http imports in your code to cz.msebera.android.httpclient.

[Kirill Karmazin]

Note: app:dependencies - here app is the name of your app module, for example myAwesomeApp

[Muhammad Saqib]

this will exclude org.apache.http.client.HttpClient what if our code is already using this library?

[srs]

then you need to find that specific library which is causing this duplicate httpclient import and need to remove the transitive httpclient dependency from that specific library.

[Muhammad Saqib]

in my case, org.apache.http.client.HttpClient was causing the conflict since android is now itself providing this library. Luckily, I found a clone github repo of org.apache.http.client.HttpClient with different name space which solved my problem.

[Muhammad Saqib]

here is the clone, just in case if anyone want to use implementation group: 'cz.msebera.android', name: 'httpclient', version: '4.4.1.2'

[Alex Lipov]

Those classes are not exposed as public API, though they are used as part of implementation. To see an example of such conflict, check this issue.

[Pratik Saluja]

Where to put this code? In App or Project Level Gradle? @Raja Peela

[Raja Peela]

@PratikSaluja App level inside android {}

[Pratik Saluja]

Weird for me it worked outside of the android block.
