Question

这只是一个从https://start.spring.io/下载的演示项目

我对此很陌生，不知道如何进行

我遇到的构建错误。

您可以像这样在POM中使用标签：

const buttonValues = ["a", "b"]  

const addingValuesToButtons = () => {
   for (var i = 0; i < buttonValues.length; i++) {
      if(buttonValues[i] === "a") {
         //add attribute name and value to first two buttons
      }
      if(buttonValues[i] === "b"){
         //add attribute name and value to first three buttons
      }
   };

   return(
     <div>
      <button> One </button>
      <button> Two </button>
      <button> Three </button>
      <button> Four </button>
     </div>
   )
}

com.example：demo：0.0.1-SNAPSHOT的不可解析的父POM
