如评论中所述，您在 Maven 命令中输入错误，请尝试 

mvn clean install

First Solution --> please enter proper commands "install"* Not "inctall" According to your screen shot in the Question

问题无法理解，您可以通过 运行 mvn build life cycle 命令找到确切的问题

第一步 = mvn validate 它将验证 pom.xml 文件和其他依赖项的

第二步=mvn compile它将编译并构建项目

第三步=mvn test它将测试所有基本情况

第四步=mvn package会给出jar/war/ear文件

第五步 = mvn verify 它将验证构建

第六步=mvn install会根据我们的pom构建工程

第七步=mvn deploy构建将部署在指定的tom cat服务器

然后你可以找到错误是什么以及在特定情况下必须解决的地方（而运行 mvn build life cycle命令）
