描述

此规则用于检查文件或项目中是否定义了变量但未使用它们。

建议

Remove variables and arguments that are not used. Workflows should only have variables and arguments that are necessary for its execution. Unused variables and arguments make the project more difficult to understand and should be removed. For removing all unused variables, use the button "Remove Unused Variables" in the ribbon, as shown here.
