To make a maven repo from a file:

• Create a directory in the workspace (repo or something)
• execute this:

define an unmanaged artifact

mvn deploy:deploy-file -Durl=file:///path/to/yourproject/repo/ -Dfile=mylib-1.0.jar -DgroupId=com.example -DartifactId=mylib -Dpackaging=jar -Dversion=1.0

add this to your POM (tell maven there is a new magical repo where you just created the unmanaged artifact)

<repositories>
    <!--other repositories if any-->
    <repository>
        <id>project.local</id>
        <name>project</name>
        <url>file:${project.basedir}/repo</url>
    </repository>
</repositories>

Now tell maven to depend on a jar (as imported in step 1)

<dependency>
    <groupId>com.example</groupId>
    <artifactId>mylib</artifactId>
    <version>1.0</version>
</dependency>

to build the executable jar:

mvn install

This will produce a directory called target

now to execute the jar:

java -jar target/Percolation-1.0-SNAPSHOT.jar src/test/input10.txt
