@Codemod(id="sonar:java/remove-unused-local-variable-s1481", reviewGuidance=MERGE_WITHOUT_REVIEW, importance=LOW, executionPriority=HIGH) public final class RemoveUnusedLocalVariableCodemod extends io.codemodder.providers.sonar.SonarPluginJavaParserChanger<com.github.javaparser.ast.body.VariableDeclarator,io.codemodder.sonar.model.Issue>
Codemod to remove unused local variables which expression is a variable or just a Literal expression like a single boolean, char, double, integer, long, null, string or a text block string. We are not considering create object expression, method call expressions, condition expressions, etc. because all of them have an expression node and that expression node could result in a method call expression where a process could be performed and deleting it could result on some unexpected behaviors.
