Re: [equinox-dev] Can I get logging corresponding to 'diag'?

I also think this is a pax exam problem.

I often have the case that pax exam tests timeout at the service injection. The reason often is a failed resolution of bundles.
I have written a small method for my tests that goes through all bundles and starts each. I then let the eventual exception simply
get thrown. So junit nicely gives me the resolution problem as the test failure.

I built a test case. What it proves is that there is no Equinox problem here, there's a pax-exam problem.

When I run Equinox directly from my own code, I get:

org.osgi.framework.BundleException: Could not resolve module: com.basistech.equinox-logging-demo-problem [2]
  Unresolved requirement: Import-Package: org.apache.commons.io; version="[1.4.0,1.4.1)"

which is perfectly fine.

pax-exam manages to obfuscate this to:

1065 [main] ERROR org.ops4j.pax.exam.nat.internal.NativeTestContainer  - Bundle [com.basistech.equinox-logging-demo-problem_0.0.1.SNAPSHOT [14]] is not resolved

So, I'll be taking this up with them.

In an effort to get a clearer picture, I tried:

java -jar ~/.m2/repository/org/eclipse/osgi/3.10.0-v20140606-1445/osgi-3.10.0-v20140606-1445.jar -console

as per the getting started page, but it just sits there. I am sure this is density on my part.

Tom,

I can do that.

Thanks.

I suggest you open a bug against Equinox with step you used to launch the framework and install/start the bundles.  I'm still a bit confused by how the errors are being logged.  Clearly a better error message should be getting logged that describes the unsatisfied requirement.

What version of Equinox are you using?  Can you give the example of the error message equinox does give you?

I'm embarrassed to  report that I've misplaced the log. I can, however, try to surround the question, as follows.


I am using, in Maven terms:

org.eclipse:osgi:jar:3.10.0-v20140606-1445

The problem was the following.

 Bundle 'fred' imports com.basistech.george;version=[34.0.0,35.0.0)

I stupidly included bundle 'george' with version 35.0.0.

The error message simply said that 'fred' could not be resolved, and cited a number in [] brackets.

Later on I can reconstruct this stupidity by checking out from the right (wrong) commit and running the build, but perhaps this is helpful?

In comparison, when I swapped in Felix, I got a lengthy diagnosis that the problem was the lack of com.basistech.george at the required version.

When I make a mistake in a manifest, and a bundle has unresolvable dependencies, the error message logged is not detailed. (For comparison purposes, felix will log the whole story.) The shell command does not help me; the situation is failing pax-exam tests, and while I could load up in the shell, I'd rather just get the sad story when the test fails.
