Maven: Including jar not found in public repository

Question

If I was to use a 3rd party library that was not in the maven public repository, what is the best way to include it as dependency for my project so that when someone else checks out my code it will still be able to build?

i.e.

My Application "A" depends on jar "B" which does not exist in the public repository. I, however, wish to add "B" as a dependency to "A" such that when a person on the other side of the world could check out the code and still be able to build "A"

Answer 1

You can install the project yourself.

Or you can use the system scope like the following:

<dependency>
    <groupId>org.group.project</groupId>
    <artifactId>Project</artifactId>
    <version>1.0.0</version>
    <scope>system</scope>
    <systemPath>${basedir}/lib/project-1.0.0.jar</systemPath>
</dependency>

systemPath requires the absolute path of the project. To make it easier, if the jar file is within the repository/project, you can use ${basedir} property, which is bound to the root of the project.
