}

repositories {
    mavenCentral()
}

dependencies {
    rewrite("org.openrewrite.recipe:rewrite-third-party:0.5.3")
}

2. Run gradle rewriteRun to run the recipe.

Gradle init script

    }
    rewrite {
        activeRecipe("tech.picnic.errorprone.refasterrules.SuggestedFixRulesRecipes$SuggestedFixSwapRecipe")
    }
    afterEvaluate {
        if (repositories.isEmpty()) {
            repositories {
                mavenCentral()
