[Also posted on http://stackoverflow.com/questions/27847999/how-to-bundle-my-maven-based-gatling-loadtest-into-one-jar]
I created a Gatling load test using the highcharts archetype. I decided against just downloading the latest Gatling ZIP file and creating a simulation within the extracted folder since I rely on a number of dependencies in public and private Maven repositories.
I want to
Maven's assembly plugin looks like an obvious candidate to solve #1. So I added the following to my pom.xml:
<plugin>
<artifactId>maven-assembly-plugin</artifactId>
<configuration>
<archive>
<manifest>
<mainClass>io.gatling.app.Gatling</mainClass>
</manifest>
</archive>
<descriptorRefs>
<descriptorRef>jar-with-dependencies</descriptorRef>
</descriptorRefs>
</configuration>
</plugin>
With this configuration, running a JAR file created with mvn clean package assembly:single
results in the following NoSuchFileException
:
$ java -jar target/myapp-0.1-SNAPSHOT-jar-with-dependencies.jar
