dm4-thymeleaf built from source: class not found error when starting bundle

[Malte]

While needing to extend the dm4-sign-up module i have trouble getting the dm48-thymeleaf-0.5.jar to start when building it from the sources. Here is the error i got after typing "start bundleId" into the GoGo? Shell.

org.osgi.framework.BundleException: Activator start error in bundle de.deepamehta.webactivator [18].

Using the one built for ​http://download.deepamehta.de i have no trouble. Can you explain this strange behaviour?

[jri]

In which directory did you build dm4-thymeleaf?
How did you deploy it?
What is the content of your bundle-deploy directory?
What does your bundle list (lb) look like?
Did you build DM from source?
Does the error persist?

The standard approach would be to build it in modules-external (in case DM is built from source) resp. bundle-dev (DM binary distro). It should be hot deployed then (by automatically being copied to bundle-deploy). Manual start via Gogo shell should not be required.

Once I recognized a similar error when having the same bundle deployed twice in Felix. Could this be the case?

Do you still have this error?
