新建的SpringBoot项目启动报 “Exception in thread "main" java.lang.IllegalArgumentException”错误解决办法

场景：
新建了个SpringBoot项目，什么都没动过，结果刚启动控制台就给抛出如下错误信息：

Exception in thread "main" java.lang.IllegalArgumentException: Cannot instantiate interface org.springframework.context.ApplicationContextInitializer : org.springframework.boot.context.ConfigurationWarningsApplicationContextInitializer

把我整懵了。。
百度了一通，无果，把以前建的项目打开启动，没问题，我寻思这也太离谱了吧。拿两个项目的pom.xml对比了一下，最后改了个版本号，好了，我哭了。

原pom.xml 部分内容如下

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.1.5.RELEASE</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>

修改后：

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.1.4.RELEASE</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>

解决办法：

把2.1.5改成了2.1.4，成了！
