Hi folks,

I just migrated to Gatling 2.3.0 and remember seeing this error - maybe https://github.com/sgoeschl/gatling-blueprint-project/blob/master/pom.xml might help

Thanks in advance, Siegfried Goeschl

[Ashley Hindmarsh]

Same here - dropped back to 2.2.4 for now.

[Stéphane LANDELLE]

No idea what you do but the problem is definitively on your side.

The demo works just fine: https://github.com/gatling/gatling-maven-plugin-demo/blob/master/pom.xml

It happens when I try to run "mvn install io.gatling:gatling-maven-plugin:test" (just the plugin directly). Simulations and running the Engine work directly (through IntelliJ)

Again, please provide a reproducer.

You can check for yourself that the command you provided works just fine against the demo:  https://github.com/gatling/gatling-maven-plugin-demo

Using gatling-maven-plugin 2.2.4 and gatling 2.3.0 fixes this problem (no definition of the scala compiler in my pom)

[Robert Bain]

I had the same problem. I followed the link to the working demo pom and used their versions and the most recent version of gatling on maven central (2.3.1 at time of writing).

The problem persisted. I noticed the following dependency in the pom I was using that was not in the demo pom:

<dependency>
    <groupId>org.scala-lang</groupId>
    <artifactId>scala-library</artifactId>
    <version>${scala.version}</version>
</dependency>

When I removed this, it worked.

I tried upgrading gatling-maven-plugin but any 3x version did not work. Here are the versions that worked for me:

<properties>

    <gatling.version>2.3.1</gatling.version>

    <gatling-maven-plugin.version>2.2.4</gatling-maven-plugin.version>

    <scala-maven-plugin.version>3.3.2</scala-maven-plugin.version>

</properties>

[Shaun Thompson]

Had the exact same problem when using the latest releases of the plugins.

<gatling.version>2.3.1</gatling.version>

<gatling-maven-plugin.version>3.0.0</gatling-maven-plugin.version>

<scala-maven-plugin.version>3.4.2</scala-maven-plugin.version>

[slan...@gatling.io]

Maven plugin 3 is to be used with Gatling 3, not 2.

[Shaun Thompson]

That was simple enough!

Using the following versions bypassed the error above.

 <gatling.version>3.0.0-RC2</gatling.version>

 <gatling-maven-plugin.version>3.0.0</gatling-maven-plugin.version>

 <scala-maven-plugin.version>3.4.2</scala-maven-plugin.version>
