在IntelliJ中使用Maven、Spring和ApacheSpark的java会导致错误
我有一个Maven Spring项目，当我在terminal中运行它时，它运行良好，没有任何错误：
java -jar myPro.jar
但是，当我在pom.xml中添加spark依赖项时，会出现以下错误：
Error: Could not find or load main class com.test.myProject.myMainClass
我的pom.xml是：
<?xml version="1.0" encoding="UTF-8"?>

导致该错误的依赖项是：
<dependency>
<groupId>org.apache.spark</groupId>
<artifactId>spark-sql_2.11</artifactId>
<version>2.4.0</version>
<exclusions>
<exclusion>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-log4j12</artifactId>
</exclusion>
<exclusion>
<groupId>log4j</groupId>
<artifactId>log4j</artifactId>
</exclusion>
</exclusions>
</dependency>
MyMain类是：
package com.test.myProject;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.PropertySource;
@Configuration
@SpringBootApplication
@PropertySource("application.properties")
public class myMainClass{
public static void main(String[] args) {
SpringApplication.run(myMainClass.class, args);
}
}
在stackoverflow中，有很多关于找不到主类的问题，我测试了几乎所有的问题，但都没有帮助，当然，其他问题不是关于添加spark依赖项后找不到主类。所以请确保，这个问题不是重复的
经过长时间的搜索和测试，我无法解决它

正如@khmarbaise所说，我已经改变了pom。xml格式如下：
通过转到项目文件夹并在其中使用
mvn clean package，问题得到了解决
