I'm wondering if there was a way to get the sigar compiled binaries ie. libsigar-universal-macosx.dylib etc.. using maven. i know that i can just manually add it but I wish to automate the deployment
In maven there are lot of way to arrange your build
Consider the following options:
Quick and dirty: Make dependency of scope 'system' put the library in the predefined place and build.
Read about the system scope here
Much better approach although requires more work: create a maven repository with the thirdparty jars that you don't have in repo 1. Although you can use http server like apache and provide an http based access to such a repository, I would recommend you to use the proxy that was build exactly for this purpose. Consider to use Nexus or Artifactory for this.
Then configure these repositories in the maven installation (all the sigar jars will be managed by this repository) and build your project.
Hope this helps

I am setting up a local repository using Apache Archiva. After setting up now I need to copy the libraries that got downloaded into my local maven repository into archiva. Currently I am manually copying it but it is very tedious process and I am planning to automate it using some scripts. Is there any better approach to do this?
I'm trying to write a plugin for this here which is able to copy jars and poms for all dependencies in all Configurations (including transitive dependencies). You might be interested in this code
Note: I've got a failing test here because I can't currently get the parent pom xml via the Gradle API's. I raised a feature request in Gradle here
There's a suggestion on the issue to use the IvyPot plugin... I haven't tried this myself but might be worth a shot.
I am trying to implement a little service in Scala using Maven to manage dependencies and I would like to add webhdfs-java-client that I have found at https://github.com/wdavidw/webhdfs-java-client
I have added to pom.xml following code:
<dependency>
<groupId>org.zxs</groupId>
<artifactId>webhdfs-java-client</artifactId>
<version>0.0.0</version>
</dependency>
It does not work, as I have expected. Does anyone could give me an advice if there exists some catalog of maven repositories (something like pip for Python)? And what can I possibly do if I'll not find this library in the catalog? Is it possible to somehow add it to maven manually?
In maven world you can install this dependency locally and resolution will be done via local cache (the one that usually resides in ~/.m2). Steps are as simple as mvn clean install in that repo. Having said this, it wouldn't resolve problem for your users (transitive dependencies, you know), which is why you likely need to publish that dependency somewhere (or ask library author whether it's published somewhere).
SBT, which is scala's de-facto build tool allows you to depend on other sbt flavored projects simply by referencing their git repository, but sadly, maven has no such feature.
I have built an internal library for my team and would like them to be able to include it in their projects using Maven. Is it possible to publish it to my private Github repository so they can access it? Ideally I would like to do this using m2eclipse without needing the Maven command line interface.
The best suggestions i can make is to use a repository manager which will make it simple to offer others the artifacts which they can use in the usual maven way via a dependency.
Update
In the nexus book it's described how to setup nexus, secure it and make restriction by user etc. to restrict access to the nexus.

I'm new to Maven, using the m2e plugin for Eclipse. I'm still wrapping my head around Maven, but it seems like whenever I need to import a new library, like java.util.List, now I have to manually go through the hassle of finding the right repository for the jar and adding it to the dependencies in the POM. This seems like a major hassle, especially since some jars can't be found in public repositories, so they have to be uploaded into the local repository.
Am I missing something about Maven in Eclipse? Is there a way to automatically update the POM when Eclipse automatically imports a new library?
I'm trying to understand how using Maven saves time/effort...
You picked a bad example. Portions of the actual Java Library that come with the Java Standard Runtime are there regardless of Maven configuration.
With that in mind, if you wanted to add something external, say Log4j, then you would need to add a project dependency on Log4j. Maven would then take the dependency information and create a "signature" to search for, first in the local cache, and then in the external repositories.
Such a signature might look like
groupId:artifactId:version
or perhaps
groupId:artifactId:version:classifier
This identifies a maven "module" which will then be downloaded and configured into your system. Once in place it adds all of the classes within the module to your configured project.
Maven principally saves time in downloading and organizing JAR files in your build. By defining a "standard" project layout and a "standard" build order, Maven eliminates a lot of the guesswork in the "why isn't my project building" sweepstakes. Also, you can use neat commands like "mvn dependency:tree" to print out a list of all the JARs your project depends on, recursively.
Warning note: If you are using the M2E plugin and Eclipse, you may also run into problems with the plugin itself. The 1.0 version (hosted at eclipse.org) was much less friendly than the previous 0.12 version (hosted at Sonatype). You can get around this to some extent by downloading and installing the "standalone" version of Maven from apache (maven.apache.org) and running Maven from the command line. This is actually much more stable than trying to run Maven inside Eclipse (in my personal experience) and may save you some pain as you try to learn about Maven.
I'm trying to check out slf4j-simple-1.6.2 from a trusted repository (preferably, SLF4J's official repo) and pull it down into an Eclipse project. I'm doing this because I need to tweak SLF4J Simple's code so that it binds to my own logging implementation.
I'm hoping there is a way to do this without having to use Maven, because I've never used Maven before and feel much more comfortable running Ant builds.
Nevertheless, I've searched SLF4J's site high and low and cannot find any trusted links to their repository.
Even once I get the project imported into Eclipse, I still need to figure out how to get it building with Ant.
Could someone please help me:
Find the repo
Confirm whether an Ant build is possible
Thanks in advance!
The zip download here also contains the sources.
The official source code repository is hosted on GitHub. However, I believe you are doing it the wrong way.
The idea of SLF4J is to have a dependency on slf4j-api and let the developer to add exactly one binding. Instead of tweaking original bindings just write your own one. Of course you can use simple binding a starting point, but modifying existing open source libraries and maintaining patched versions is a lot of work.
As you said, slf4j is present in the official Maven repository.
So basically, you have 2 simple solutions without using Maven:
Download the JAR / sources / javadocs from this Maven repository, and copy them in your own project directory.
Use Ivy. This is an extension of Ant to give a better dependencies management. It can connect to Maven repositories. So you will be able to retrieve your slf4j dependency without having to use Maven.
