Gradle - Library Duplicates in Dependencies

gradle - library duplicates in dependencies

To find duplicate dependencies or its required dependencies, you can visualize library dependencies in tree. Execute gradle command as below.

gradle -q dependencies yourProject:dependencies --configuration compile

Note that, run gradlew in Windows as below.

gradlew -q dependencies yourProject:dependencies --configuration compile

The command result will show you human-readable tree hierarchy of all dependencies as below.

compile - Classpath for compiling the main sources.
+--- org.androidannotations:androidannotations-api:3.2
+--- com.android.support:support-annotations:22.1.1
+--- com.squareup:otto:1.3.6
+--- in.srain.cube:grid-view-with-header-footer:1.0.10
+--- com.nostra13.universalimageloader:universal-image-loader:1.9.3
+--- com.github.chrisbanes.photoview:library:1.2.3
+--- org.simpleframework:simple-xml:2.7.1
+--- com.google.android.gms:play-services-base:6.5.+ -> 6.5.87
+--- project :yourProject
|    +--- com.loopj.android:android-async-http:1.4.6
|    +--- org.apache.httpcomponents:httpmime:4.2.5
|    |    \--- org.apache.httpcomponents:httpcore:4.2.4
|    \--- com.google.code.gson:gson:2.3.1
+--- project :facebook
|    \--- com.android.support:appcompat-v7:22.1.1
|         \--- com.android.support:support-v4:22.1.1
|              \--- com.android.support:support-annotations:22.1.1 -> 22.2.0

You can see overriden dependencies and decide in mind which ones should be avoided. In above example, last line com.android.support:support-annotations presents overriden from 22.1.1 to 22.2.0 internally.

To avoid duplicates, you can add exclude clauses in each project build.gradle file.

compile('com.github.chrisbanes.photoview:library:1.2.3') {
    exclude group: 'com.android.support'
}

compile('org.simpleframework:simple-xml:2.7.1') {
    exclude module: 'stax'
    exclude module: 'stax-api'
    exclude module: 'xpp3'
}

compile('com.google.android.gms:play-services-base:6.5.+') {
    exclude module: 'support-v4'
}

Gradle: How to check for duplicate dependencies in project?

You can use ./gradlew projectName:dependencies to see a tree of all the dependencies of your project. Both that are repeated or with different versions are remarked in the different configurations and classpaths.

How to Remove Duplicate Libraries added via gradle?

Instead of adding it in the Configurations. I added the exclude for only the library like this:

compile ('com.rengwuxian.materialedittext:library:1.7.1') {
   exclude group: 'com.nineoldandroids', module: 'library'
}

Resolve duplicated external libraries in Android Studio

This might be because of something called as Transitive dependency. Lets say you are using android core library version 1.5.0 and you are also using an another library say XyzImage library. Now the XyzImage library internally depends on the android core library version 1.2.0. Now due to this your app dependency tree would look like as follow:

-- Your App
 +-> AndroidCore@1.5.0
 +-> XyzImageLibrary@1.1.0
     +-> AndroidCore@1.2.0

Now the XyzImageLibrary can configure it's gradle file in such a way that the gradle should only use the 1.2.0 version of the AndroidCore library while processing the XyzImageLibrary files. Due to this, gradle would need to download multiple version of same library. You can lookup the dependency tree of your Android App by following the solution https://stackoverflow.com/a/35235229/5309486 .

Android build.gradle Exclude duplicate classes

You can find all the dependencies of your project with the command

./gradlew :app:dependencies

Bitmovin and Purchasely seems to both use exoplayer.
So to avoid conflicts you can remove the module exoplayer from either one of those dependencies.

In your case, I think you should remove it from Purchasely

implementation ("io.purchasely:core:2.4.7") {
    exclude module: 'exoplayer-core'
    exclude module: 'exoplayer-hls'
    exclude module: 'exoplayer-dash'
    exclude module: 'exoplayer-ui'
    exclude module: 'extension-okhttp'
    exclude module: 'extension-mediasession'
}

Android Duplicate Dependencies

Seems you have included same library file twice

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

compile fileTree(dir: 'libs', include: 'gson-*.jar')

compile fileTree(dir: 'libs', include: 'Parse-*.jar')

So it seems that gson-*.jar and Parse-*.jar are included twice.

Edit:

As you said the problem is with umano sliding up library, then it should be the problem of its dependencies.

dependencies {
    compile 'com.android.support:support-v4:22.2.1'
    compile 'com.android.support:support-annotations:22.2.1'
    compile 'com.android.support:recyclerview-v7:22.2.1'
    compile 'com.nineoldandroids:library:2.4.0'
}

And I have check com.baoyz.pullrefreshlayout:library, it has the following dependency

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:support-v4:21.0.0'
}

so you included 2 versions of support library, and thus having the problem.

compile 'com.baoyz.pullrefreshlayout:library:1.0.1'

To fix the problem, replace the line above to the one below.

compile('com.baoyz.pullrefreshlayout:library:1.0.1') { 
{
    exclude group: 'com.android.support', module: 'support-v4'
}

In addition to the above, setup multidex following the guide below
