Errore nella compilazione di com.squareup.retrofit: convertitore-simplexml: 2.0.0-beta2

Quindi sono in procinto di convertirmi in Retrofit 2.0. Tuttavia quando provo ad aggiungere il convertitore Simple XML al mio build.gradle non verrà più compilato.

Ecco le mie dipendenze

dependencies { compile fileTree(dir: 'libs', include: ['*.jar']) testCompile 'junit:junit:4.12' compile 'com.android.support:appcompat-v7:23.1.1' compile 'com.android.support:design:23.1.1' compile 'com.squareup.retrofit:retrofit:2.0.0-beta2' compile 'com.squareup.okhttp:logging-interceptor:2.6.0' compile 'com.squareup.retrofit:converter-simplexml:2.0.0-beta2' //THIS LINE compile 'com.google.code.gson:gson:2.3' compile 'org.parceler:parceler:0.2.13' compile 'com.jakewharton:butterknife:7.0.1' } 

e quando vado a compilare il mio codice ottengo il seguente errore:

 trouble processing "javax/xml/XMLConstants.class": Ill-advised or mistaken usage of a core class (java.* or javax.*) when not building a core library. This is often due to inadvertently including a core library file in your application's project, when using an IDE (such as Eclipse). If you are sure you're not intentionally defining a core class, then this is the most likely explanation of what's going on. However, you might actually be trying to define a class in a core namespace, the source of which you may have taken, for example, from a non-Android virtual machine project. This will most assuredly not work. At a minimum, it jeopardizes the compatibility of your app with future versions of the platform. It is also often of questionable legality. If you really intend to build a core library -- which is only appropriate as part of creating a full virtual machine distribution, as opposed to compiling an application -- then use the "--core-library" option to suppress this error message. If you go ahead and use "--core-library" but are in fact building an application, then be forewarned that your application will still fail to build or run, at some point. Please be prepared for angry customers who find, for example, that your application ceases to function once they upgrade their operating system. You will be to blame for this problem. If you are legitimately using some code that happens to be in a core package, then the easiest safe alternative you have is to repackage that code. That is, move the classs in question into your own package namespace. This means that they will never be in conflict with core system classs. JarJar is a tool that may help you in this endeavor. If you find that you cannot do this, then that is an indication that the path you are on will ultimately lead to pain, suffering, grief, and lamentation. 

Questo errore non è una novità per la comunità, semplicemente non capisco come si applica al mio progetto. Non ho ancora scritto alcun codice e non riesco a compilare le mie dipendenze di base. Se commento questa linea

 compile 'com.squareup.retrofit:converter-simplexml:2.0.0-beta2' 

Il codice viene compilato. Quindi questo è sicuramente il colpevole in un modo o nell’altro.

L’ho riparato. A quanto pare devi escludere alcune cose.

 compile ('com.squareup.retrofit:converter-simplexml:2.0.0-beta2') { exclude group: 'xpp3', module: 'xpp3' exclude group: 'stax', module: 'stax-api' exclude group: 'stax', module: 'stax' } 

Spero che questo aiuti qualcun altro
