add external jar to our dependency

There is a jar file lets say "abc.jar" which maven dependency does not exist(ie created a jar by using java command of own classes). I want to add this jar as maven dependency so that at build time it will automatically copy that jar in lib folder as like other maven dependency. how i will do. please help .

A normal maven dependency is always resolved by looking into a repository. So you must put your JAR file into a repository.

You could install your JAR into your local repository. Have a look at the install plugin. The install-file goal is your friend.

If other developers also need this JAR (because they are working with the same project), they either need to install it locally too, or - better - you deploy the JAR to a remote repository. Have a look at the deploy plugin. Here the deploy-file goal is your friend. For deploying artifacts, you need a repository manager like Nexus or Artifactory.

However, a dependency could also have the system scope (look at the other answers).

You can use the systemPath attribute in the dependency tag in the POM file of your project.

In your pom.xml, use the following snippet corresponding to abc.jar:

<dependencies>
  <!-- Other dependencies -->
  <dependency>
    <groupId>abc</groupId>
    <artifactId>x</artifactId>
    <version>1.0</version>
    <scope>system</scope>
    <systemPath>{path_to_abc.jar}</systemPath>
  </dependency>
</dependencies>

The scope parameter corresponding to this artifact must be set to system, for the artifact to be picked up from the specified systemPath.

Hope this helps!

Add it as a dependency with a system scope. See the docs here.

However, rather than adding it as a system dependency it might be better to mavenize the jar itself, then you can build and install it into your dependency management system.

Also, see this question: Can I add jars to maven 2 build classpath without installing them?
