java.lang.RuntimeException: Can't find the jar matching scala-library.*\.jar$

Gatling (Open-Source)

Hello,

I am having problems integrating a Gatling execution as a Maven profile in my project. The profile goes like this:

performance

io.gatling
gatling-maven-plugin
${gatling.version}

test1
test

execute

When executing “mvn install -P performance”, I have this problem:

I have not found documentation of this error over Internet. The only similar question is this one: http://stackoverflow.com/questions/34340481/if-i-run-a-plugin-from-the-command-line-at-the-root-pom-what-does-it-do-when-tr
But it fails to give me a clue about what is happening :frowning:

Can you please help me?

Thank you very much

Gatling version is 2.2.0, by the way.

I suspect you’re missing the scala library dependency.
Create a fresh project from the maven archetype.

Thank you, that was the problem. I have created a new project with the archetype, and I have copied the contents of its pom.xml to my project. Now it works :slight_smile:

Great !
