我通过右键单击Project-> Run AS-> Spring Boot App，在STS中运行项目。

我试图清理和更新Maven，清理并重建项目。.仍然出现相同的错误..请帮助我，我们还能做些什么来删除此异常。??

Answer 1

在pom文件中包含以下依赖项，然后执行mvn package：

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

在Spring Boot中作为java.lang.ClassNotFoundException：org.apache.tools.ant.Project出现错误
