+
+Il est fort probable que le keystore java n'ait pas le certificat de la forge à jour (ce qui est probable avec LetsEncrypt).
+
+Dans ce cas:
+
+1. Se connecter sur la machine Jenkins en SSH avec le compte `root`
+2. Si le script `/root/install-java-cert.sh` n'existe pas encore, le créer avec le contenu suivant:
+
+    ```
+    #!/bin/sh
+
+    set -xe
+
+    DOMAIN=$1
+    JENKINS_HOME=/var/lib/jenkins
+    JAVA_HOME=/usr/lib/jvm/default-jvm
+
+    if [ -z "$DOMAIN" ]; then
+      echo "You must specify the domain as first argument"
+      exit 1
+    fi
+
+    # Import certificate
+    openssl s_client -showcerts -connect "$DOMAIN" < /dev/null 2> /dev/null | openssl x509 -outform PEM > ~/root_ca.pem
+
+    # Duplicate Java Keystore file and move into Jenkins...
+    mkdir -p $JENKINS_HOME/keystore/
+    cp $JAVA_HOME/jre/lib/security/cacerts $JENKINS_HOME/keystore/
+
+    # Add Certificate to Keystore
+    keytool -import -alias $DOMAIN -keystore $JENKINS_HOME/keystore/cacerts -file ~/root_ca.pem
+
+    # Add -Djavax.net.ssl.trustStore=$JENKINS_HOME/keystore/cacerts to the
+    # Jenkins startup parameters. For Debian/Ubuntu, this is /etc/default/jenkins
+    mkdir -p /etc/default
+    echo 'JAVA_ARGS="$JAVA_ARGS -Djavax.net.ssl.trustStore=$JENKINS_HOME/keystore/cacerts"' >> /etc/default/jenkins
+
+    rc-service jenkins restart
+    ```
+
+3. Lancer le script `/root/install-java-cert.sh forge.cadoles.com:443`. Le mot de passe par défaut du keystore est `changeit`.
