[jira] Commented: (SMX4-354) OSGi bundles and versioning

["Jean-Baptiste Onofré (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/activemq/browse/SMX4-354?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=54111#action_54111 ] 

Jean-Baptiste Onofré commented on SMX4-354:
-------------------------------------------

The bundles-pom pom.xml already contains the correct version policy instruction.

I have updated the following bundles:
- commons-codec
- commons-beanutils
- cglib

> Importing their own package may lead to real problems when deploying two
> different versions of such a bundle.  There is a high chance that the second
> one will use the classes from the first one instead of their own classes.
> Version ranges are also important to avoid some problems if the bundle is
> wired to a dependent bundle with a new major version.
> First, we need to upgrade to the maven-bundle-plugin 2.0.0 (in the parent
> pom for all bundles).
> We need to add the following instruction for the maven bundle plugin:
>      <_versionpolicy>[$(version;==;$(@)),$(version;+;$(@)))</_versionpolicy>
> Then for each bundle, we need to make sure each package exported is not
> imported.   For example, if we have:
>    <Export-Package>org.apache.commons.codec*</Export-Package>
> we need to add the following to imports:
>     !org.apache.commons.codec*
> This line needs to be added at the beginning of the Import-Package
> declaration.
