Not building with current milo version

[gbrost]

Hi,

great project idea, we really could use this. However, if i try to build with most current milo, i get this error:

Could you give me hand there?

Thanks Gerd

Yes. I will try to fix this today. In the last days Milo wasn't really stable, from an API perspective.

[ctron]

I just checked, the problem should be solved by the changes I already made last week.

Simply re-open this issued if you still encounter any issues.

[gbrost]

Thank you very much! It is building now. Just one question: Did you ever encounter the problem that a milo-based route does not start? I tried to deploy the example route from your project. The log outputs:

2016-11-28 15:00:34,454 | INFO | FelixStartLevel | BlueprintContainerImpl | 34 - org.apache.aries.blueprint.core - 1.6.1 | Bundle camel-opc-timer-to-rest.xml/0.0.0 is waiting for namespace handlers [http://camel.apache.org/schema/blueprint]

And bundle:diag prints:

Bundle 255

Status: GracePeriod Blueprint 11/28/16 3:48 PM Missing dependencies: (&(objectClass=org.apache.aries.blueprint.NamespaceHandler)(osgi.service.blueprint.namespace=http://camel.apache.org/schema/blueprint))

Thanks!

[gbrost]

Sorry, posted my reply in german language first, out of habit. Translated to english now.

[ctron]

Looks like you are missing OSGi blueprint support. This is available in karaf as "camel-blueprint" IIRC.

[gbrost]

I get the feeling this is a "wrong error message" problem or a bug in my karaf version. I describe the problem here. I was just wondering if this could somehow be related to milo, since other routes seem to deploy fine.

[ctron]

I get a "page not found" by this link.

[gbrost]

Sorry, i messed up the link. I fixed it, please try again :)

[ctron]

Hm .. I see. This seems rather strange to me. Can you make some sort of reproducer, like a few lines of instructions how to get to this problem.

[gbrost]

I now found the root of the problem. You are dependent on Camel 2.18, right? I was on a branch where we did not upgrade yet. Upgrading to Camel 2.18 fixes the problem. Thank you very much!

[gbrost]

Sorry for needing your help again: I had my test route up and running (at least it was contacting my OPC-UA server). I restarted karaf and now it get this error:

Obviously com.google.common.base is missing. But how could it be running before? Could you give me a hand finding the root of the problem?

How did you install the milo component? Using the Karaf feature? It should already declare the dependency on Guava.
