Duplicate import
Hi,
When I try to start just one bundle, the 'log4j-1.2.16.jar' bundle, I
get this error:
Auto-deploy install: org.osgi.framework.BundleException: Duplicate
import - com.sun.jdmk.comm
Google doesn't help me here.
Could you help me?
The maven directory: http://repo1.maven.org/maven2/log4j/log4j/1.2.16/
Thank you in advance,
Peter

There is no default for package versions, so if you don't specify one
then it doesn't get one. In your case, it might be simplest just to
specify the bundle version (i.e., JAR version) as the package version
for all exported packages otherwise.

Unfortunately, older versions of the BND tool make a simplifying
decision to import all exports, which you most likely don't want to do,
since you are creating a library bundle. I am hoping that we can update
maven-bundle-plugin to use the newer versions of BND that have a few
more heuristics for generating imports for exported package.
I generated a log4j bundle using a newer version of BND and ended up
with the attached manifest file, where you can see it no longer imports
the exports. You can achieve this in the current plugin with an export
like this:
<Export-Package>!org.apache.log4j.lf5.*,!org.apache.log4j.chainsaw.*,org.apache.log4j.*;-noimport:=true</Export-Package>
Once we get a new plugin release, it will hopefully make better default
choices for this issue.

I inadvertently specified that class twice in the Import-Package element in the log4j's POM. I just noticed the typo when writing that last sentence. I was ready to report it as a bug in maven-bundle-plugin since I thought that it had duplicated the entry. However, it would have been nice for the bundle plugin to warn about it.
Before seeing the typo, I had committed a modified pom.xml and have checked that it successfully starts in Equinox.

- Thank you Richard, I deleted the line (and some others) manually.
It works now.
- The problem is: It's the latest and only version of log4j that
supports OSGi (and that is deployed on the Maven repo).
Yours,
Peter

Looking at its manifest, I see:
Import-Package: com.ibm.uvm.tools;resolution:=optional,com.sun.jdmk.co
mm;resolution:=optional,com.sun.jdmk.comm;resolution:=optional,javax.
The package is imported twice, not sure why, but that is an error. Try a
different version.
