I am trying to configure Eclipse to be able to run gatling test. I have a file that I created using Gatling recorder, however in eclipse I get bunch of errors like grizzled-slf4j\_2.9.2-0.6.10.jat is cross-compiled with an incompatible version of Scala(2.9.2) any ideas why I am getting this? ---

I got past this issue, but now I am getting [ERROR] Failed to execute goal com.excilys.ebi.gatling:gatling-maven-plugin:1.3.4:execute (default-cli) on project gatling-maven-project: Gatling failed.

Honestly, I have no idea what you’re doing and what happens on your project. Could you please provide: - eclipse version - Scala IDE plugin version (and check that it’s the one for Scala 2.9, not Scala 2.10) - m2e version - m2e-scala version Stéphane This set up is plug-and-play, for real!!! ---

honestly, I am having such a hard time just to get a simple test working in eclipse. I know its all me, but I can’t figure it out. I installed Maven 3.0.5 I installed eclipse with the Scala IDE m2e version 1.3 m2e-scala version 3.0.0.v-2\_10-201303191346-dac2f1c Scala plugin version reads 3.0.0.v-2.10-201… All I want to do is create a project in eclipse to run my Gatling test. ---

Hi, It looks like you’re using an old version of Gatling (1.3.4). You should update to 1.5 😉 (open pom.xml, look for gatling.version, change the version and you’re done) Looks like you’re using the Scala 2.10 version of Scala IDE, but Gatling 1.X uses Scala 2.9… Cheers, Pierre ---

Bull’s eye! Here’s a procedure, please stick to it! - Download eclipse Juno (4.2) classic (no need for JEE) - Help \> Install New Software \> Add =\> install Scala IDE 3.0.0 (with Scala 2.9 for Gatling \< 2, with Scala 2.10 for Gatling \>= 2, if you want to you both, you’ll need 2 separate eclipse installations and workspaces) - Help \> Install New Software \> Add =\> install everything from scala-m2e (it has the latest m2e too, and no need for maven, it has an embedded version) - Maven \> Archetypes \> Add Remote Catalog =\> add Excilys catalog - New \> Other \> Maven \> Maven Project =\> create a new project with gatling archetype - Run As \> Scala Application =\> Recorder for recording and Engine for simulating Beware that we don’t support old Gatling versions, upgrade to 1.5. Like always, eclipse behaves much much better if you use a recent JVM and that you tune it properly in eclipse.ini. Here are my options: -Xmn256m -Xmx2048m -Xss2m -XX:MaxPermSize=256m -XX:+HeapDumpOnOutOfMemoryError -XX:+AggressiveOpts -XX:+OptimizeStringConcat -XX:+UseFastAccessorMethods -XX:+UseParNewGC -XX:+UseConcMarkSweepGC -XX:+CMSParallelRemarkEnabled -XX:SurvivorRatio=8 -XX:MaxTenuringThreshold=1 -XX:CMSInitiatingOccupancyFraction=75 -XX:+UseCMSInitiatingOccupancyOnly -XX:+CMSClassUnloadingEnabled ---

Thank you so much for your help. Both you and Pierre. I finally have this working.
