Duplicate libraries in two different project modules

问题

I have project with two modules. I'm using SalesforceSDK which is included as separate module and inside SalesforceSDK I have Cordova which is using okhttp. In second module I have retrofit library which is using okhttp too and when I try to build the project I get

duplicate dex files error

I tried to delete okhttp dependency from SalesforceSDK and include it from my second module but I'm getting

symbols not found error

Only thing left to do is to include okhttp as different module but before I do that I want to ask you if there is another way to fix this problem ?

EDIT:

I tried solution proposed by Aayushi but still I get errors :

Error:Execution failed for task ':app:packageAllDebugClassesForMultiDex'.

java.util.zip.ZipException: duplicate entry: com/squareup/okhttp/Address.class

回答1:

if you are using android studio no need to delete you can use both library

just use

android {
    defaultConfig {
     ...
      multiDexEnabled = true
  }
}

using this statement is also required

dependencies 
{
    compile 'com.android.support:multidex:1.0.0'
}

I also have another solution for this issue. Firstly, I run this command line:

and this is result:

I saw that Paypal also use okhttp library.So, I added this line to gradlew:

compile('com.paypal.sdk:paypal-android-sdk:2.13.3')
        {
            exclude group: 'com.squareup.okhttp3', module: 'okhttp'
        }

And It aslo works fine for me.

Take a look at jarjar, which can let you use one version of OkHttp in one place and another somewhere else.

There are other similar tools (shade), and most of ‘em will work for you.
