Je n’arrive plus à compiler avec maven le projet Asqatasun et le plugin Jenkins
suite à la mise à jour de l’OS d’un ordinateur (de Ubuntu 14.04 à Ubuntu 16.04). 
Avant cette mise à jour, les paquets maven et openjdk-7-jdk étaient installés à partir des dépôts officiels. Après la mise à jour, la compilation n’est plus possible. Pour Ubuntu 16.06, le paquet openjdk-7-jdk n’est plus disponible et c’est openjdk-8-jdk qui le remplace.

J’ai réglé l’erreur “JAVA_HOME environment variable is not set”
en utilisant les commandes suivantes :
JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64/ PATH="$PATH:/usr/lib/jvm/java-8-openjdk-amd64/bin" export PATH JAVA_HOME
mais le résultat n’est pas meilleur (je n’ai pas conservé les logs).
A ce stade je ne suis pas sûre que JDK était installé (le JRE oui)
et j’ai oublié de faire un javac -version (je faisais uniquement un java -version).
Nouvelle tentative en installant openjdk-7-jdk à partir du dépôt ppa:openjdk-r/ppa
mais la compilation bloquait pour le sous-projet asqatasun-web-app
Dernière tentative en désinstallant maven et tous les paquets openjdk-*
puis en installant dans la foulée maven et openjdk-8-jdk.
La configuration actuelle de l’environnement est :
sudo lsb_release -a No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 16.04.1 LTS Release: 16.04 Codename: xenial
sudo java -version openjdk version "1.8.0_91" OpenJDK Runtime Environment (build 1.8.0_91-8u91-b14-3ubuntu1~16.04.1-b14) OpenJDK 64-Bit Server VM (build 25.91-b14, mixed mode)
sudo javac -version javac 1.8.0_91

La compilation du plugin Jenkins fonctionne maintenant.
Par contre pour le projet Asqatasun
elle échoue pour le sous-projet asqatasun-engine .
Une idée ? 
Ci-dessous le log maven :
