Upgrade from Optaplanner Failure: Missing rewrite() Method in upgrade-timefold.gradle Script

Describe the bug
Gradle build fails with an exception when running the upgrade script for Timefold Solver. The error indicates that the rewrite() method is not found.

Expected behavior
he Gradle build should complete successfully, applying the necessary upgrades without any errors.

Actual behavior
The build fails with the following error message:

No signature of method: org.gradle.api.internal.artifacts.dsl.dependencies.DefaultDependencyHandler.rewrite() is applicable for argument types: (org.codehaus.groovy.runtime.GStringImpl) values: [ai.timefold.solver:timefold-solver-migration:1.15.0]
Possible solutions: wait(), wait(long), create(java.lang.Object), with(groovy.lang.Closure)
> Could not find method rewrite() for arguments [ai.timefold.solver:timefold-solver-migration:1.15.0] on object of type org.gradle.api.internal.artifacts.dsl.dependencies.DefaultDependencyHandler.

To Reproduce

1. Run the following command in the terminal:

curl https://timefold.ai/product/upgrade/upgrade-timefold.gradle > upgrade-timefold.gradle
gradle -Dorg.gradle.jvmargs=-Xmx2G --init-script upgrade-timefold.gradle rewriteRun -DtimefoldSolverVersion=1.15.0

Additional information

The issue seems to be related to the rewrite() method not being available in the DefaultDependencyHandler class. This might be due to a missing plugin or an incorrect method call in the [upgrade-timefold.gradle] script.

Start with the downloaded upgrade-timefold.gradle script and reproduce the failure using the provided curl and Gradle command. Inspect why rewrite() is invoked on DefaultDependencyHandler and confirm the upgrade script completes rewriteRun successfully with timefoldSolverVersion=1.15.0.
