Missing p2 site for yakindu plugin

[lwrage]

Summary

From @Etienne13 via google group:

I have downloaded Eclipse 2019-12 R, modelling tools (https://www.eclipse.org/downloads/packages/release/2019-12/r/eclipse-modeling-tools).

I cannot install OSATE 2.7.0 in this environment from the update site (http://osate-build.sei.cmu.edu/download/osate/stable/2.7.0/updates/).

Expected and Current Behavior

Here is the error message I get:

Cannot complete the install because one or more required items could not be found.
Software being installed: Open Source AADL Tool Environment Graphical Editor Developer Resources 3.0.0.v20200201-1852 (org.osate.ge.feature.source.feature.group 3.0.0.v20200201-1852)

Environment

• OSATE Version: 2.7.0
• Operating System:

Workaround:

Add http://updates.yakindu.com/statecharts/releases/3.5.9 as an p2 site to Eclipse before installing OSATE (Help -> Install New Software... -> type the URL into field "Work with:" -> "Enter" key). That URL is missing from our p2 repository's list of external sites.
