Is there a maven repository for JCS 1.4-SNAPSHOT. I've searched the Apache repositories, but can't seem to find it. Also is JCS still under active development? The mailing lists seem to be down.
Thanks.
I have checked Maven Central there you will find a 1.3 release but i have rechecked the SNAPSHOT repository of the project and couldn't find a up-to-date release. The current site is of the 19.feb 2012 ..so not that old. But if you don't get an answer on the mailing list Hm...

I had a maven project which I successfully deployed to Sonatype.
All the checks were successful.So,I released it from Sonatype.
But even though Maven Central Sync has been activated,the project I released is not yet been released to Maven Central Repository.
Can anyone please suggest solution for this?
The artifacts should be published to central in 10-15 minutes, but it can take up to several hours before you'll see them in the search results at https://search.maven.org.
If it's been longer than that file an issue at https://issues.sonatype.org in the "Community Support - Maven Central" and we'll look into this for you.
Has anyone been successful in building an eclipse plugin for Juno against the CDH4 installation?
I've seen CDH3 all over the net. Looking for CDH4.
Thanks much.
I'm not sure if you're referring to the Hadoop Eclipse plugin or a plugin to develop code against CDH4. I'll answer both questions.
Developing against CDH4 in Juno:
By far, the easiest way to write applications against CDH4 components in Eclipse (any version), is by using m2eclipse[1] and adding the Cloudera Maven repository to your pom.xml. In fact, a significant portion of folks at Cloudera (including myself), do this regularly. Recently, one of our engineers (Natty) wrote a nice blog post about getting started with CDH4, Maven, and Eclipse[2] (and other IDEs). Otherwise, nothing special is required to write apps against CDH4 other than having the JARs around. You can also browse through the Cloudera Maven repository here[3].
The Hadoop Plugin:
Long ago, a plugin for Eclipse existed that allowed for MR job execution and some other bits. It has, however, been unmaintained for a very long time (at least two to three years now). I don't think anyone ever updated it to work with Juno--, let alone Juno, itself.
Hope this helps.

I followed the instructions found at: http://iredlof.com/part-4-compile-hadoop-v1-0-4-eclipse-plugin-on-ubuntu-12-10/
System: Local: Windows 7, Eclipse Juno (4.2.2), hadoop-1.2.1. Remote: Debian 7.1 with the same hadoop version.
I should mention that I built the plugin against vanilla hadoop-1.2.1 freshly downloaded from apache.
Not everything works with the plugin: I can add new MR location (remote in my case), I can browse/upload/download/delete files from DFS, but BUT I cannot run my code (using Run as ... Run to Hadoop). The console writes "ClassNotFoundException: WordCountReducer"
A good thing is that the jar generated by eclipse can be manually uploaded to MR master and started from command line.
You can get Hadoop Eclipse plugin at this GitHub Repository. https://github.com/winghc/hadoop2x-eclipse-plugin.

I am upgrading an system I have been developing for some time now to JBoss AS 6 (6.0.0-Final). Everything works well with JBoss but I can't find a maven repository. I read the information on their web-site which directs me to: https://repository.jboss.org/nexus/content/repositories/releases
However it only contains Jboss 4.2.3.GA?!
I believe that my question is incorrect. This is what I believe is the correct answer:
Maven2 always uses http://repo1.maven.org/maven2/ as a fallback when packages are not found in the repositories supplied. So one should supply the jboss repository, https://repository.jboss.org/nexus/content/groups/public-jboss/, but it will only contain jboss specific packages. For everything else (javaee packages and so on) the maven2 fallback reposity should be used.
I didn't understand that a Maven2 repository was always used as a fallback. So I got confused when I couldn't find the packages I needed in the Jboss repository.
The groupId has changed to org.jboss.as
Here are some 7.x Alpha releases
And here are some 6.x release links through nexus (couldn't find a browsable version of these)
I want to start using maven in code I distribute but I can't find an efficient way to work with dependencies. Every new dependency takes me far too long to add.
As a simple example, I need to add Tomcat for compilation. Do I really have to manually trawl the repo in my browser to find the group-id, artifact-id and version number?
In every case it seems easier to find the non-maven downloads. I hope I've missed something obvious.

No. Use a repository search engine. Some are mentioned here, more here. Some IDE also offer facilities to search and add dependencies (e.g. Eclipse with m2eclipse).
First of all, using some IDE really helps. Eclipse has m2eclipse plugin and if you define locations of remote maven repositories in your pom definition, you can add dependencies in its pom editor and it will automatically search the proper artifacts for you.
What is really helpful is using repository manager like Nexus / Artifactory, where you gather the most important maven repositories and then you don't need to declare particular repository locations in your pom definition for various artifacts, but everything will be proxied via Nexus.
I have a stable opensource library and was wondering how (and if) I can publish my lib to maven official repositories so people can include it in their pom.xml files and get the dependency downloaded automatically.
The process to get your library in the central repostiory is documented in the Guide to uploading artifacts to the Central Repository. In short, the new process is to get your project hosted by one of the approved Forges that will be synced with central, the Maven folks don't rsync personal repository anymore. In your case, your best bet would be to use the Sonatype Forge (open to any OSS Project). Check the given link (and also this document).
If you want reliable access for everyone out there, you need to stick with central. Due to the tendency of people at dev.java.net to break rules about the immutability of released artifacts, some people don't trust it. Further, it can be Very Slow.
To get your project into central, you need have your code in some public repo that they can sync from.
Central repository
A bit less bureaucratic dev.java.net Maven2 repository - allows completely automatic deployment.
