Error using Retrofit Rest Adapter : NoClassDefFoundError: Retrofit.Restadapter$Builder

Question

My application always crashes when i instantiate the RestAdapter

private void submitForm(SignupForm form){
    RestAdapter adapter = new RestAdapter.Builder()
                .setEndpoint(ENDPOINT)
                .build();
        SignUpApi signUpApi = adapter.create(SignUpApi.class);
    signUpApi.sendStudentForm(form);
}

i also included retrofit.jar file and Gson.jar file. There is similar question here but i dont use gradle.

I fix this issue by add

packagingOptions {
    exclude 'META-INF/maven/com.squareup.retrofit/retrofit/pom.properties'
    exclude 'META-INF/maven/com.squareup.retrofit/retrofit/pom.xml'
}

in gradle.

My network lib

compile 'com.squareup.okio:okio:1.6.0'
compile 'com.google.code.gson:gson:2.6.2'
compile 'com.squareup.retrofit2:retrofit:2.0.1'
compile 'com.squareup.retrofit2:converter-gson:2.0.1'
compile 'com.squareup.okhttp3:logging-interceptor:3.2.0'
compile 'com.squareup.okhttp3:okhttp:3.2.0'
compile 'com.squareup.okhttp3:okhttp-urlconnection:3.2.0'
