Hi Alex, Bnd 4.0.0 was only released last Sunday, but this should have been changed yesterday in this commit https://github.com/osgi/osgi.enroute/commit/9f9857c3d317cd08a7aaf7327c1904676299f9ee to make sure enRoute kept building.
EnRoute is automatically pushed to the sonatype OSGi nexus repository, so is it possible that you’re running offline, or firewalled from the repo? You should be able to force snapshot updates from the Maven command line.
