Extension "guacamole-auth-jdbc-postgresql-1.4.0.jar" could not be loaded
Hi,
I'm running guacamole-client 1.4.0:
# grep VERSION /var/lib/tomcat-8.5-hmn/webapps/HMNsg/translations/en.json
"VERSION" : "1.4.0",
but I'm seeing this in the log:
[localhost-startStop-1] DEBUG o.a.g.extension.ExtensionModule - Reading extension: "guacamole-auth-jdbc-postgresql-1.4.0.jar"
[localhost-startStop-1] ERROR o.a.g.extension.ExtensionModule - Extension "guacamole-auth-jdbc-postgresql-1.4.0.jar" could not be loaded: Authentication provider class cannot be loaded (wrong version of API?).
[localhost-startStop-1] DEBUG o.a.g.extension.ExtensionModule - Unable to load extension.

The version of Guacamole is downloaded from the Guacamole home page, but I think I must have gotten the GIT version instead. Now I re-built the 1.4.0, and I do not get the extension error anymore.
Sorry for the confusion.
Thanks,
Vieri

HMNsg seems like a slightly odd name - just to confirm, are you running a
standard version of Guacamole downloaded from the Guacamole home page? Have
you made any modifications to any source code? Do all of your downloads -
both the WAR and the extensions - come from the same download location?
