Add Jar and Classifier as dependency to Maven project

Question

I have a local Jar file that I want to add as a dependency for a Maven project that I am working on.

That is easy to do as this answer states.

The problem is that this Jar file requires a foo.classifier file to work properly.

This Jar file is meant to be run by command line (java -jar bar.jar {argument}). The Jar and the classifier files are in the same directory, so everything works just fine.

However, from my project, I want to call the Jar file using its methods and not running a process.

I added the Jar file as a dependency and managed to call the main method that receives the argument, however, it doesn't work properly because of the foo.classifier the file is not set as a dependency for that Jar file to work.

Does anyone know how can I set it as a dependency of that Jar file?

How are you using foo.classifier files in jar. Reading from classpath or physical path? — Vikas, Feb 25 '19 at 13:50
Can you edit the sources and build the `bar.jar` file yourself? — Daniele, Feb 25 '19 at 13:52
I was not the one who coded the Jar file, so I don't know how it is used. I only know that both the jar and classifier files must be in the same directory. Also, I can not edit the sources. — João Alves, Feb 25 '19 at 13:56
Do you have the sources and can read the sources of the main method? — J Fabian Meier, Feb 25 '19 at 14:07

Put foo.classifier files in exact folder in .m2\repository folder where your local Jar file that you added as a dependency is present as dependency jar will be referred from local repository

This sounds brittle to me. – J Fabian Meier Feb 25 '19 at 14:31
This is like having jar and files together in the same directory – Vikas Feb 25 '19 at 14:33
But local repositories are often deleted, recreated etc. – J Fabian Meier Feb 25 '19 at 19:43

You can put your jar to libs directory,and add below code into your pom.xml file:

<dependency> <groupId>htmlunit</groupId> <artifactId>htmlunit</artifactId> <version>2.21-OSGi</version>`` <scope>system</scope> <systemPath>the full path of the jar</systemPath> </dependency>

scope system should be avoided if possible. – J Fabian Meier Feb 25 '19 at 14:31
I can't emphasized this strong enough what JF Meier said. – khmarbaise Feb 25 '19 at 17:42
Yeah,JF Meier is right and I am just talking about a way to use local jar files with Maven. – bp zhang Mar 26 '19 at 09:52

Add the jar to maven repository with the follows command line, specify a group id, artifact id and a version

mvn install:install-file -Dfile="my-local.jar" -DgroupId="my.groupid" -DartifactId="name" -Dversion="1.0.0" -Dpackaging=jar

and then add as dependency to your pom

<dependency>
    <groupId>my.groupid</groupId>
    <artifactId>name</artifactId>
    <version>1.0.0</version>
</dependency>
