Codenameone: Erreur de construction lors de l'intégration de Codename One Bibliothèque de transfert de données native

J'ai essayé d'intégrer cn1lib pour le transfert de données natif, qui est disponible sur la page Extensions. Malheureusement, lorsque cette bibliothèque est intégrée, certaines erreurs de construction apparaissent: Certaines classes awt sont manquantes (par exemple, import java.awt.Component;).Codenameone: Erreur de construction lors de l'intégration de Codename One Bibliothèque de transfert de données native

Je ne sais pas, ce qui manque exactement pour obtenir la construction.

Voici la console-sortie avec l'erreur de construction:

Comment avez-vous installé la bibliothèque? Grâce Codename Un paramètres, ou d'une autre manière? –

Grâce à la section settings - y compris l'appel de "refresh Libs" – KlausHeywinkel

Pouvez-vous lister les erreurs exactes que vous avez? Les obtenez-vous en cliquant sur le projet et en faisant une construction? –

Il semble y avoir un bogue dans le modèle Eclipse build.xml dans la version actuelle. J'ai appliqué un correctif qui sera inclus avec la prochaine mise à jour du plugin. En attendant, vous devrez apporter une petite modification à votre fichier build.xml.

Vers la ligne 170 de votre build.xml, il y a un appel javac:

<javac destdir="native/internal_tmp" compiler="modern" 
      source="1.8" 
      target="1.8" 
      bootclasspath="lib/CLDC11.jar" 
      classpath="lib/CodenameOne.jar:${build.classes.dir}:lib/impl/cls:build/tmp"> 
      <src path="native/javase"/> 
      <src path="lib/impl/native/javase"/> 
     </javac>

Retirez la ligne bootclasspath=, si vous vous retrouvez avec:

<javac destdir="native/internal_tmp" compiler="modern" 
      source="1.8" 
      target="1.8" 
      classpath="lib/CodenameOne.jar:${build.classes.dir}:lib/impl/cls:build/tmp"> 
      <src path="native/javase"/> 
      <src path="lib/impl/native/javase"/> 
     </javac>
