Dynamically Link To Latest 'jar-with-dependencies' From Maven Central

Question

I'm trying to use the Maven central API to provide dynamic download links for the latest versions of an artifact. While this works for a normal jar, I cannot seem to get it to link to the 'jar-with-dependencies' version of the artifact.

Using the com.ning:nagios artifact, the latest can be downloaded at

http://repository.sonatype.org/service/local/artifact/maven/redirect?r=central-proxy&g=com.ning&a=nagios&v=LATEST

I had assumed that I could use the l query param (based on the linked API) to specify the 'jar-with-dependencies' classifier but the link only downloads the normal jar.

http://repository.sonatype.org/service/local/artifact/maven/redirect?r=central-proxy&g=com.ning&a=nagios&v=LATEST&l=jar-with-dependencies

Is there any way to link to this version of the artifact?

Answer 1

It turns out the classifier parameter is 'c' for the redirecting download service, not 'l' as used in the Solr API (in that API 'c' is for 'classname') - so this will work:

https://search.maven.org/remote_content?g=com.ning&a=nagios&v=LATEST&c=jar-with-dependencies

(note, updated after Sonatype put BASIC auth on the old url - we use this new official download url on maven.org instead now)

It downloads the 1.2MB jar that includes dependencies (not the regular jar) - currently the latest version is nagios-0.0.2-jar-with-dependencies.jar.
