jar1: /home/trantrungtruc/.m2/repository/org/elasticsearch/jna/4.5.1/jna-4.5.1.jar
jar2: /home/trantrungtruc/.m2/repository/net/java/dev/jna/jna/4.1.0/jna-4.1.0.jar

You are having in your classpath 2 jars. You should exclude net/java/dev/jna/jna/4.1.0/jna-4.1.0.jar from your build I think.
If you are using maven, run:

mvn dependency:tree

To see which dependency is bringing this jar and exclude it in your pom.xml.

Throwable #1: java.lang.NoClassDefFoundError: org.elasticsearch.test.ESTestCase

May be you did not include all the needed libs for testing? How did you build your project?
