Dans le but de montrer la n\u00e9cessiter d’encoder les fichiers sources d’une application Android, j’ai eu besoin d’utiliser dex2jar, un outil permettant d’extraire les fichiers .class d’une paquet .dex (pour la VM Dalvik d’Android).<\/p>\n

Comme je pr\u00e9f\u00e8re avoir tous mes paquets g\u00e9r\u00e9s par portage (gestionnaire de paquets Gentoo), j’ai d\u00e9cid\u00e9 d’\u00e9crire un ebuild pour la version courante (la 0.0.7.9-SNAPSHOT).<\/p>\n

 <\/p>\n

Tout d’abord, pour tester l’ebuild (par exemple la suppression des .bat destin\u00e9s \u00e0 windows), il suffit d’utiliser cette commande jusqu’\u00e0 avoir le r\u00e9sultat d\u00e9sir\u00e9:<\/p>\n

ebuild dex2jar-0.0.7.9.ebuild digest &&<\/span> rm<\/span> \/<\/span>var\/<\/span>tmp\/<\/span>portage\/<\/span>dev-util\/<\/span>dex2jar-0.0.7.9\/<\/span> -rf<\/span> &&<\/span> FEATURES<\/span>="test"<\/span> ebuild dex2jar-0.0.7.9.ebuild test<\/span><\/span><\/code><\/p>\n

Ensuite, dans le r\u00e9pertoire dev-util\/dex2jar\/files<\/em> de l’overlay, il faut placer le fichier dex2jar<\/strong> suivant:<\/p>\n

\r\n#!\/bin\/sh\r\n\r\nexec \/opt\/dex2jar\/dex2jar.sh ${1}\r\n<\/pre>\n
L’ebuild final, dex2jar-0.0.7.9.ebuild<\/strong> est \u00e0 placer dans l’overlay sous dev-util\/dex2jar<\/em><\/p>\n
