Another option is to use the Apache Maven Shade Plugin: This plugin provides the capability to package the artifact in an uber-jar, including its dependencies and to shade - i.e. rename - the packages of some of the dependencies.

add this to your build plugins section

<plugin>
     <groupId>org.apache.maven.plugins</groupId>
     <artifactId>maven-shade-plugin</artifactId>
</plugin>

May be your dependencies not build correctly. Check compilation issue in project.

Clean and rebuild project.

For maven project: mvn clean install

For gradle projects: gradle clean build or gradlew clean build
