The sawn off error message:

  ... D:\Karthikeyan\ElasticSearch\ElasticSearch_Tesing\target\dependency-

suggests that you need to change the outputDirectory configuration of the maven-dependency-plugin to:

                    <configuration>
                        <!-- exclude junit, we need runtime dependency only -->
                        <includeScope>runtime</includeScope>
                        <outputDirectory>
                            ${project.build.directory}/dependency-jars/
                        </outputDirectory>
                    </configuration>

to get rid of the newline in the middle the value.

Thankyou., it fixed my issue., now am getting this error while executing my jar file `Error: Could not find or load main class ProjectJar.project.App`. My main class package name is `com.es.utility.DocumentIndex` so do i need to give my full package name instead of `ProjectJar.project.App`..? (in my pom.xml file) – Karthikeyan Jul 08 '18 at 06:35
If i add `com.es.utility.DocumentIndex` am getting `Error: Could not find or load main class com.es.utility.DocumentIndex` error – Karthikeyan Jul 08 '18 at 12:52
