Issue in executing gatling-maven-plugin:2.1.6 on jenkins -

Gatling (Open-Source)
1

Hi

I’m running into issues in running my gatling project on Jenkins. Its working fine on my local, but not able to build through Jenkins.

These are my versions:

<gatling.version>2.1.6</gatling.version>
<gatling-plugin.version>2.1.6</gatling-plugin.version>
<scala-maven-plugin.version>3.2.2</scala-maven-plugin.version>

I did see posts on issues when we have spaces in the job name, and paths. I had made sure I’ve no spaces in the path to my Jenkins war, gatling project and Jenkins Job name.

This is the error I’m seeing, when running with -X enabled:

Error: Could not find or load main class Files is typical of a java command line where some space messes everything up.
You’re running on Windows, so there’s a very good chance your JDK is located in Program Files, that… contains a space!

Try adding a logback-test.xml that sets the logging level to DEBUG, you might see the full command line.

Hi Antony

I am facing the same issue where my gatling-maven project is throwing an error, “Error: Could not find or load main class Files”

Were you able to fix the issue that you got? If yes, could you please share how?

I do not have any spaces in my paths. Also, I have the following versions:

<gatling.version>2.1.7</gatling.version>
<gatling-plugin.version>2.1.7</gatling-plugin.version>
<scala-maven-plugin.version>3.2.2</scala-maven-plugin.version>

Thanks in advance!

Regards

Were you able to resolve this issue?
If yes, how?

Thanks.

I had the same issue,

So I created a junction (directory link in ntfs) between C:\Java and C:\Program Files\Java using the command

mklink /J C:\Java “C:\Program Files\Java”

Afterwards I set the JAVA_HOME variable to C:\Java\jdk…

That worked for me in command line, BUT: as soon as I run the maven build from Intellij it failed with the same error - unless I start the build in debug mode o_O … however, I suspect the IntelliJ Launcher and the IntelliJ installpath to be the culprit, because the Gatling process is forked from the maven process and presumably inherits some of its commandline args:

C:\Java\jdk1.8.0_65\bin\java … “-Didea.launcher.bin.path=C:\Program Files (x86)\JetBrains\IntelliJ IDEA 15.0.2\bin” -classpath “D:\tools\apache-maven-3.3.3\boot\plexus-classworlds-2.5.2.jar;C:\Program Files (x86)\JetBrains\IntelliJ IDEA 15.0.2\lib\idea_rt.jar” com.intellij.rt.execution.application.AppMain org.codehaus.classworlds.Launcher -Didea.version=15.0.4

I re-installed IntelliJ in another directory WITHOUT spaces, and that did it for me.
