NoClassDefFoundError while running .jmx command line using lazerycode jmeter plugin

1. It is recommended to use latest versions of JMeter, its Maven plugin and JMeter Plugins so I would recommend amending your pom.xml like:

   <project xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://maven.apache.org/POM/4.0.0"
            xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
       <modelVersion>4.0.0</modelVersion>
       <groupId>com.example</groupId>
       <artifactId>mvn-jmeter</artifactId>
       <version>1.0-SNAPSHOT</version>
       <name>maven-jmeter-demo</name>
       <url>http://maven.apache.org</url>
       <build>
           <plugins>
               <plugin>
                   <groupId>com.lazerycode.jmeter</groupId>
                   <artifactId>jmeter-maven-plugin</artifactId>
                   <version>2.7.0</version>
                   <executions>
                       <execution>
                           <id>jmeter-tests</id>
                           <phase>verify</phase>
                           <goals>
                               <goal>jmeter</goal>
                           </goals>
                       </execution>
                   </executions>
                   <configuration>
                       <jmeterExtensions>
                           <artifact>kg.apc:jmeter-plugins-json:jar:2.6</artifact>
                           <artifact>kg.apc:jmeter-plugins-manager:0.19</artifact>
                           <artifact>kg.apc:jmeter-plugins-extras-libs:1.4.0</artifact>
                       </jmeterExtensions>
                       <downloadExtensionDependencies>false</downloadExtensionDependencies>
                   </configuration>
               </plugin>
           </plugins>
       </build>
   </project>
   

2. It might be an issue with Maven caches so I would suggest running it at least once with -U key like:

   mvn -U clean verify
   

3. If you still experience problems run your test with -X key to enable full debugging output and update your question with it (you might also need to provide your .jmx script)

EDIT: Thanks Dmitri, this was really helpful. In my case I had to add additional library in the pom.xml to resolve this error.

<artifact>com.jayway.jsonpath:json-path:2.2.0</artifact>

I am editing this answer because more often, people don't look into comments to get the answer.
