Strange artifact/pom setting in Maven Central...

[Sam Husson]

Folks,

I came across an unusual situation where a nexus search for json-lib
(GAV: net.sf.jason-lib:json-lib:2.3:jar) returned -- among other things
-- an entry with packaging jar where the pom does not have a classifier
or anything so that I could rationally expect to find both in our nexus
file system and in the remote Maven Central repo the following
artifact... net/sf/json-lib/json-lib/2.3/json-lib-2.3.jar.  Well, on our
file system we see only the pom.  In maven central we see
json-lib-2.3-jdk13-javadoc.jar                     11-Jul-2009 22:40
245582
json-lib-2.3-jdk13-sources.jar                     11-Jul-2009 22:40              102390
json-lib-2.3-jdk13.jar                             11-Jul-2009 22:40              151390
json-lib-2.3-jdk15-javadoc.jar                     11-Jul-2009 22:40              248751
json-lib-2.3-jdk15-sources.jar                     11-Jul-2009 22:40              104049
json-lib-2.3-jdk15.jar

This suggests that a classifier should be specified.  Sure enough, when I added <classifier>jdk15</classifier> to my dependency I got the correct jar.

My questions:

1 - How is it that the pom in does not specify a classifier yet json-lib-2.3.jar doesn't exist?
2 - How can nexus list the following in a search for json-lib:
        version         packaging       classifier      Download
        2.3             jar                             artifact,pom

yet clicking the pom link shows this dependency...
<dependency>
  <groupId>net.sf.json-lib</groupId>
  <artifactId>json-lib</artifactId>
  <version>2.3</version>
</dependency>

Instead of
<dependency>
  <groupId>net.sf.json-lib</groupId>
  <artifactId>json-lib</artifactId>
  <version>2.3</version>
  <classifier>whatever</classifier>
</dependency>


I hope this loaded question is not too confusing.

Hi Sam,

This was a bug on nexus 1.3.6 and it is already fixed on 1.4.0 (to be released in a few days).

If you wanna try
