Create the release and publish to update site.

I am unable to perform the release. Unfortunately I did neither fully automate nor document the release process and the last release was 5 years ago.

[ERROR] Failed to execute goal org.eclipse.tycho:tycho-packaging-plugin:1.3.0:validate-version (default-validate-version) on project net.sf.mmm.eclipse.templatevariables.plugin: Maven version 1.1.0 must have -SNAPSHOT qualifier for SNAPSHOT builds -> [Help 1]

There are other users having such issues:

However, no helpful answer was given in the thread.
