Jmeter with maven and using external groovy scripts issues with groovy imports

Question

I'd like to execute jmeter tests from maven using groovy scripts, but I got the error below. For setting up jmeter and maven I did what is described here .

Shall I package my groovy functions and entities into a jar and copy into jmeter's lib directory and only put those groovy scripts next to the jmx file which contains the sampler code?

2019-06-22 17:40:17,714 INFO o.a.j.s.SampleResult: sampleresult.useNanoTime=true
2019-06-22 17:40:17,714 INFO o.a.j.s.SampleResult: sampleresult.nanoThreadSleep=5000
2019-06-22 17:40:17,744 ERROR o.a.j.p.j.s.JSR223Sampler: Problem in JSR223 script CreateUsers, message: javax.script.ScriptException: org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:

Answer 1

You need to add to your pom.xml Gson dependency

 <dependency> <groupId>com.google</groupId> <artifactId>gson</artifactId> <version>2.1.0</version> </dependency> 

Answer 2

I found the answer:

• I need to package into jars my libraries I'd like to use in testing and put them into jmeter/lib directory
• I have to align Sampler scripts path, so jmeter can work with them

The solution for the first is the following from jmeter-maven-plugin doc:

<project>
    [...]
        <build>
            <plugins>
                <plugin>
                    <groupId>com.lazerycode.jmeter</groupId>
                    <artifactId>jmeter-maven-plugin</artifactId>
                    <version>USE LAST VERSION</version>
                    <executions>
                        <execution>
                            <id>jmeter-tests</id>
                            <goals>
                                <goal>jmeter</goal>
                            </goals>
                        </execution>
                    </executions>
                    <configuration>
                        <testPlanLibraries>
                             <artifact>org.apache.activemq:activemq-spring:5.15.2</artifact>
                 <artifact>org.apache.activemq:activemq-client:5.15.2</artifact>
                 <artifact>org.apache.activemq:activemq-broker:5.15.2</artifact>
                </testPlanLibraries>
                        <excludedArtifacts>
                             <exclusion>com.sun.jdmk:jmxtools</exclusion>
                             <exclusion>com.sun.jmx:jmxri</exclusion>
            </excludedArtifacts>
                    </configuration>
                </plugin>
            </plugins>
        </build>
    [...]
</project>

The solution for the second is that I need to copy Sampler scripts next to jmx file. Maven can do this easily using maven-resource-plugin .
