在Spring boot中以java.lang.ClassNotFoundException:org.apache.tools.ant.Project的形式出现错误

在运行SpringToll套件（版本：3.9.5.RELEASE）中使用SpringBoot应用程序运行SpringBoot应用程序时，我收到一个错误，名为java.lang.ClassNotFoundException:org.apache.tools.ant.Project

我通过右键单击project-->run as-->Spring Boot App在STS as中运行项目

我试图清理和更新maven，清理和重建项目。。仍然得到相同的错误。。请帮助我，我们还可以做些什么来删除此异常。？

在pom文件中包含以下依赖项，然后执行

mvn包

：

<dependency>
    <groupId>org.apache.ant</groupId>
    <artifactId>ant</artifactId>
    <version>1.8.2</version>
</dependency>

org.apache.ant
蚂蚁
1.8.2

已经有一个内置的web starter依赖项，我添加了apache tomcat嵌入依赖项，因此添加单独的依赖项（您在回答部分中提供的org.apache.ant）不会影响project中的其他依赖项？？谢谢你的解决方案，我现在肯定会尝试一下，然后尽快回到u。谢谢。先生。在添加了ant依赖项之后，它工作得很顺利。@user2715085我很高兴它能帮上忙
