Exception in thread "main" java.lang.UnsatisfiedLinkError: Cannot find TensorFlow native library for OS: linux, architecture: x86_64

Question

I am trying setup TensorFlow Java application in Eclipse Oxygen (OS: Ubuntu Linux 16.x). I installed Tensorflow and followed the process mentioned in official documentation for Java (Maven Project) installation. I downloaded libtensorflow-1.3.0.jar, jni files and included in the build path. When I execute the program I get this following error

Exception in thread "main" java.lang.UnsatisfiedLinkError: Cannot find TensorFlow native library for OS: linux, architecture: x86_64. See https://github.com/tensorflow/tensorflow/tree/master/tensorflow/java/README.md for possible solutions (such as building the library from source). Additional information on attempts to find the native library can be obtained by adding org.tensorflow.NativeLibrary.DEBUG=1 to the system properties of the JVM.

App.java

package com.tensorflow.malwaredetection;

import org.tensorflow.TensorFlow;

/**
 * Hello world!

 */
public class App 
{
    public static void main( String[] args )
    {
        System.out.println( "Hello World!"+ TensorFlow.version() );
    }
}

I got tired of this error and tried to do this in an old-fashioned way. Created App.java in a separate folder and included jar, jni files in the same directory. When I execute this from command line, I get different error

dev@ubuntu:~/Downloads$ javac -cp libtensorflow-1.3.0.jar Test1.java
dev@ubuntu:~/Downloads$ java -cp libtensorflow-1.3.0.jar:. -Djava.library.path=./jni Test1
Error: Could not find or load main class Test1

I think you need to include jni library dependency in your pom.

<dependency>
    <groupId>org.tensorflow</groupId>
    <artifactId>libtensorflow_jni</artifactId>
    <version>1.1.0</version>
</dependency>
