How to use Bitbucket as a maven remote repository?

You can try http://synergian.github.io/wagon-git/index.html it has instructions for bitbucket.

An alternative to using bitbucket is to use a dropbox folder for company. https://code.google.com/p/peter-lavalle/wiki/MavenOnDropBox Contains a very good step by step guide on how to do this.

Install jars in a local maven repository.

Make a directory e.g. maven-repo/repository

cd into maven-repo

execute the following (replacing the arguments by the ones that are relevant to your jar):

mvn install:install-file -DgroupId=com.rapid_i -DartifactId=rapidminer -Dversion=5.3.006 -Dfile=/path/to/artifact/rapidminer.jar -Dpackaging=jar -DgeneratePom=true -DlocalRepositoryPath=./repository  -DcreateChecksum=true

Share the folder to a BitBucket public repository.

Create a repository in your pom.xml pointing to you bitbucket folder.(you must use /raw/master in the path https://bitbucket.org/your-user-or-group/your_maven-repo/raw/master/ !!)

<project xmlns="http://maven.apache.org/POM/4.0.0"     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"     xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><groupId>org.activeintel</groupId><artifactId>rapidminer-proj</artifactId><version>0.0.1</version> <!-- Dependency to jar on Maven Repository on Git-BitBucket --><dependencies>    <dependency>        <groupId>com.rapid_i</groupId>        <artifactId>rapidminer</artifactId>        <version>5.3.006</version>    </dependency></dependencies><!-- Maven Repository on Git-BitBucket --><repositories><repository>    <id>neil_rubens-repository</id>    <url>https://bitbucket.org/your-user-or-group/your_maven-repo/raw/master/repository/</url></repository></repositories></project>

How can I push my company specific project jars into the above remote repository using the project specific pom.xml?

You can't. shouldn't in my opinion.

Bitbucket is not intended to be a maven repository. Trying to get maven to deploy artifacts to BitBucket to it is just wrong may contravene Atlassian's terms of use. On the other hand it might be fine.

You either need to should instead deploy to your own local repository or a public one.
