Artifacts disappearing from maven central?

Question

Over the course of the last few hours, the following artifact seems to have disappeared from maven central:

groupId: org.apache.jena artifactId: jena-jdbc version: 1.1.0

It was there, my project was building just fine, then all of a sudden:

$ curl -I "http://repo.maven.apache.org/maven2/org/apache/jena/jena-jdbc/1.1.0/jena-jdbc-1.1.0.jar" HTTP/1.1 404 Not Found Server: nginx Content-Type: text/html Content-Length: 168 Accept-Ranges: bytes Date: Mon, 22 Sep 2014 08:55:35 GMT Via: 1.1 varnish Connection: keep-alive X-Served-By: cache-iad2121-IAD X-Cache: MISS X-Cache-Hits: 0 X-Timer: S1411376135.762460,VS0,VE53

What's going on here? Will it mysteriously come back? What can cause this to happen? Has anyone seen this before?

FWIW: The workaround is easy, download and install locally... but why did it go away?

Answer 1

I think you have the wrong URL.

Didn't you mean eg jena-jdbc-core?

http://repo1.maven.org/maven2/org/apache/jena/jena-jdbc-core/1.1.0/
