Just a short update to say that the mentioned issue appears also when importing project from the quickstart, for example the switchyard-quickstart-camel-jpa-binding projects. As these projects are supposed to work properly, I reckon that there is an issue between switchyard and its itergration in tooloing/JBDS.
By the way, I have imported the whole switchyard directory and, among the 99 included projects, I'm not sure that there is one which builds correctly. I imported the projects as maven projects and I have configured the JBDS maven as being the one installed on my local workstation. And of course, building the quickstarts with maven in command line mode works properly.
So, JBDS 8.1 doesn't seem to be switchyard ready.
Sorry but I was out for the Thanksgiving holiday.
The issue you describe is due to an issue (Issue Navigator - JBoss Issue Tracker) which will be fixed in the upcoming release of JBDSIS 8.0.4 (8.0.3 is out now, but 8.0.4 is on the way).
If you need to get past the issue before then, you can download the latest Luna updates before 8.0.4 is available by adding this update site - SwitchYard Tooling - Development Milestone Eclipse Update Site: 2.0.1.CR3 - and installing the latest Luna-based tooling for SwitchYard.
Hope that helps!
JBDS 9.0.0.GA is out already since a while and fixes all these issues. But it brings others :-(
