It looks like some of the artifacts aren’t getting flipped to public in the igniterealtime maven repo. In particular, “webadmintld”
[WARNING] The POM for org.igniterealtime.openfire:webadmintld:jar:4.6.4 is missing, no dependency information available
Looking in the repo, only 4.2.0 is there as a release, and 4.3.0 as a snapshot. It looks like this hasn’t been published since 2017. As the example plugin pom.xml file (https://github.com/igniterealtime/openfire-exampleplugin/blob/master/pom.xml) uses “${openfire.version}”, this breaks a plugin if I try to build it against Openfire 4.6.4 for instance.
