Subject Re: [jira] Commented: (FELIX-396) Plugin should allow to specify -split-package directive
Date Thu, 18 Oct 2007 13:10:05 GMT
Hear! Hear!

Felix, I agree. This is a real warning, if you have it, then the same
packages on the class path multiple times with different content. This
is a source for extremely obscure and hard to debug errors.

Kind regards,

     Peter Kriens

FMJ> In fact, this message is very valuable exactly because of the

FMJ> And yes, there are many projects out there, which just pack too

FMJ> So I opt for not doing anything here - except perhaps enhancing documentation on the
wiki page.

>> When using plugin with <Embed-Transitive>true</Embed-Transitive> and
more or less complex dependency tree it is really easy to receive the following warning:
>> [WARNING] Warning building bundle org.foo:boo-bundle:bundle:0.0.1 : There are split
packages, use directive -split-package:=(merge-first|merge-last) on instruction to get rid
of this warning: META-INF, classpath: [Jar:., <skipped>] from: C:\repo\commons-io\commons-io\1.3.1\commons-io-1.3.1.jar
>> Ideally plugin should take care of this by using Maven's dependency resolution mehanisms,
so there won't be any conflicting jars.
>> Also note that when <Embed-Dependency>*;inline=false</Embed-Dependency>
and above warning happens, plugin also include multiple versions of the jar file into the
result bundle.
