Timefold migration command is not working could it be that the command is wrong?

Question

Recently I've tried to migrate my OptaPlanner project with the help of the maven command found on the official Timefold website but no matter what I do it doesn't seem to work. I've tried ChatGPT(obviously no help), I tried deleting the repository folder found under ${username}/.m2/repository, still no help.

As you can see I've separated my project and optaplanner to speed up the process of generating a schedule in other words.. microservices. But that shouldn't matter it should just migrate some dependencies.

Anyways, any help is welcomed! The project is written in SpringBoot Java

Answer 1

This looks to me like a Windows-specific problem, not caused by Timefold Solver. Consider the command:

mvn org.openrewrite.maven:rewrite-maven-plugin:4.46.0:run -Drewrite.recipeArtifactCoordinates=ai.timefold.solver:timefold-solver-migration:0.8.41 -Drewrite.activeRecipes=ai.timefold.solver.migration.ToLatest

The error message complains of .recipeArtifactCoordinates not being a valid Maven plugin. This tells me that the command line was parsed incorrectly and that there is some specific syntax one needs to use to make this work on Windows, and specifically in PowerShell.

This question very likely has your answer.
