How to solve 'Maven cannot resolve dependencies' on ARM architecture?

Question

My java project is working properly on classical architecture, i.e. Von Neumann architecture. However, maven is unable to resolve dependencies on my Jetson AGX, i.e. ARM architecture. What do I need to change to compile my project on the ARM architecture? Are the corresponding packages available on maven?

The pom.xml:

    <dependencies>
        <dependency>
            <groupId>org.deeplearning4j</groupId>
            <artifactId>deeplearning4j-core</artifactId>
            <classifier>aarch64</classifier>
            <version>1.0.0-beta4</version>
        </dependency>
        <dependency>
            <groupId>org.nd4j</groupId>
            <artifactId>nd4j-native-platform</artifactId>
            <classifier>aarch64</classifier>
            <version>1.0.0-beta4</version>
        </dependency>
        <dependency>
            <groupId>javax.mail</groupId>
            <artifactId>mail</artifactId>
            <classifier>aarch64</classifier>
            <version>1.4</version>
        </dependency>
        <dependency>
            <groupId>org.junit.jupiter</groupId>
            <artifactId>junit-jupiter-api</artifactId>
            <classifier>aarch64</classifier>
            <version>RELEASE</version>

        </dependency>

            <version>4.0.1</version>
        </dependency>
    </dependencies>

Answer 1

Try removing your local m2 directory completely and run mvn clean install OR try " mvn clean install -U" command, This will force update the snapshot dependency .
