Gatling Recorder - Recorder execution failed

Gatling (Open-Source)
1

Gatling version: 3.13.1
Gatling flavor: java
Gatling build tool: maven
Maven Version: Apache Maven 3.9.9
Java Version: jdk 11.0.25 (Adoptium OpenJDK Windows x64)
OS: Windows 11

I have just downloaded the latest version of Gatling Open-Source SDK Java version from:
Download | Gatling →
gatling-maven-plugin-demo-java-main.zip

I am able to run the Gatling simulation successfully with the cmd:

mvnw.cmd gatling:test

However, I am unable to run the Gatling Recorder with the cmd:

mvnw.cmd gatling:recorder

I keep getting the following exception:

[ERROR] Failed to execute goal io.gatling.gatling-maven-plugin:4:12:1:recorder (default-cli) on project gatling-maven-plugin-demo-java: Recorder execution failed: UnsupportedOperationException
Caused by: org.apache.maven.plugin.MojoExecutionException: Recorder execution failed
Caused by: java.lang.UnsupportedOperationException
at java.util.AbstractList.add (AbstractList.java:153)

Appreciate if someone can help provide a solution for this issue.

That was indeed a regression bug, thanks for reporting!
It’s now fixed, please upgrade gatling-maven-plugin 4.12.2.
