Echec de la création de Gradle lorsque proguard est activé

J'essaie de libérer mon application Android avec Gradle.

Tout fonctionne, y compris le ./gradlew clean build assembleRelease commande.

Cependant, dès que j'essaie d'utiliser proguard, Gradle ne parvient pas à créer la version.

Voici l'erreur que je reçois (trace de pile activée):

Est-ce que quelqu'un a une idée de quel est le problème?

Modifier: ./gradlew clean assembleDebug fonctionne parfaitement! et ./gradlew clean build assembleRelease fonctionne si runProguard est désactivé. C'est donc un problème 100% proGuard.

Je lutte contre ce problème depuis quelques heures. Fondamentalement, la tâche proguard arrêtera l'exécution s'il y a des avertissements. Vous pouvez voir les avertissements Proguard et le stacktrace en ajoutant -d à la construction (comme dans: gradle clean assembleRelease -d). Notez que le stacktrace mentionne "Veuillez corriger les avertissements ci-dessus en premier."

Afin d'arriver à un point où la construction passerait à travers proguard, je devais ajouter -dontwarn entrées pour les paquets dont il se plaignait auprès de mon proguard-project.txt fichier. Quelque chose dans le genre de:

-dontwarn org.Apache.lang.**

...etc

Donc, faites simplement… faites comme le stacktrace vous le demande. Fixer les avertissements! :)

BTW, je m'excuse, car je reconnais maintenant que le stacktrace du message d'origine n'est pas tout à fait le même que celui que j'ai rencontré. Cependant, j’estime que ma réponse est utile, car j’ai bien évidemment fini par chercher ici des réponses à mon problème.

Hmmm, je ne comprends pas pourquoi mais il semble que si je commence deux fois la même tâche avec les mêmes paramètres (proguard ...), la seconde est la bonne.

Mais si le second paramètre change, la tâche échoue.

J'espère que ça va aider quelqu'un.

Vous pouvez utiliser -ignorewarnings dans proguard-project.txt pour ne pas avoir à spécifier chaque paquet.
