Note: there were 12 duplicate class definitions.that is the key. Sometimes different libraries will import other libraries in order to work, and in some cases, you will have the same dependency-library but with a different version. A silly example; a library will importcom.android.support.appcompat-v7-26.1.0and another will importcom.android.support.appcompat-v7-25.2.0. Now, you will have to search for duplicated libraries in your project, and that can take some time...
