Stian, apologies for the confusion.
I had been trying to "fix" the referenced bundles as specified in
taverna-parent. Quite a lot of the ones where we used springsource
bundles now have bundles created by the code originators. Also, because
of confusion in mvnrepository, some supposed "jars" were actually
bundles all along and need not have ever used springsource bundles.
I think it is safest to revert the parent pom to one that T3 CLT can
build against and then slowly slowly update the bundle versions.
