Maven deployment onto heroku issue for ORtools + Import for local maven dependency not appearing

I am trying to use the jar file for google OR tools as a dependency in order for it to run on heroku, because on heroku I get this error

 $ ./mvnw -DskipTests clean dependency:list install

I decided the solution would be solved using this process : https://devcenter.heroku.com/articles/local-maven-dependencies

I followed it step by step and yet the local maven dependency isnt showing up when I try to import it

This is whats in the pom.xml

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

</dependencies>


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

I added another change in order to try to draw the .dylib file directly but that still didnt work, I replaced

Loader.loadNativeLibraries();

for the ortools with

String filePath = new File("").getAbsolutePath();
        filePath = new File(filePath+"/ortools/ortools-darwin-x86-64/libjniortools.dylib").getAbsolutePath();
        System.load(filePath);

And while this works locally, I get this error on heroku

java.lang.UnsatisfiedLinkError: /app/ortools/ortools-darwin-x86-64/libjniortools.dylib: /app/ortools/ortools-darwin-x86-64/libjniortools.dylib: invalid ELF header

I still have yet to find a different solution to get OR-tools onto heroku
