Control flow statement indentation

org.openrewrite.staticanalysis.ControlFlowIndentation

Program flow control statements like if, while, and for can omit curly braces when they apply to only a single statement. This recipe ensures that any statements which follow that statement are correctly indented to show they are not part of the flow control statement.

    }
    rewrite {
        activeRecipe("org.openrewrite.staticanalysis.ControlFlowIndentation")
    }
    afterEvaluate {
        if (repositories.isEmpty()) {
            repositories {
                mavenCentral()
