sonar 3.5.1 installation error in tomcat 6.0.32 plugin name
org.sonar.l10n.gwt

After deploying jenkins successfully into tomcat on Linux RED HAT 6.1
(64b), I tried to deploy war sonar file (3.5.1 version)
Sonar doesn't start because of a resource bundle error:
2013.08.29 10:37:04 ERROR o.s.s.p.Platform Can't find bundle for base
name org.sonar.l10n.gwt, locale en
java.util.MissingResourceException: Can't find bundle for base name
org.sonar.l10n.gwt, locale en at
java.util.ResourceBundle.throwMissingResourceException(ResourceBundle.java:1539)
~[na:1.6.0_20]
at java.util.ResourceBundle.getBundleImpl(ResourceBundle.java:1278)
~[na:1.6.0_20]
I searched on a Codehaus repo and I found various versions of
org.soanr.l10n.gwt (Spanish, Japanese, French, Chinese) but no en version.
I think that's a problem. I tried to force locale to French in catalina.sh
but this doesn't work:
if [ -z "$LOGGING_MANAGER" ]; then
JAVA_OPTS="$JAVA_OPTS
-Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager
-Duser.language=fr -Duser.region=FR"
else
JAVA_OPTS="$JAVA_OPTS $LOGGING_MANAGER -Duser.language=fr -Duser.region=FR"
