Cannot Compile Spring Boot Project after Update to New Version

Question

I updated my Spring Boot Application from 1.3.4 to 1.4.3 and refreshed the project using the Gradle Refresh. I now have an error in my main application class:

• The project was not built since its build path is incomplete. Cannot find the class file for java.lang.Object. Fix the build path then try building this project BeverageDataServices Unknown Java Problem

• The type java.lang.Object cannot be resolved. It is indirectly referenced from required .class files

  BeverageDataServicesApplication.java /BeverageDataServices/src/main/java/com/boelter/beverage

Here is the main application class:

package com.xxx.beverage;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration;
import org.springframework.boot.autoconfigure.mail.MailSenderAutoConfiguration;
import org.springframework.boot.orm.jpa.EntityScan;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Import;
import org.springframework.scheduling.annotation.EnableScheduling;

@SpringBootApplication (exclude = {DataSourceAutoConfiguration.class, MailSenderAutoConfiguration.class})
@ComponentScan(basePackages = "com.xxx.xxx")
@EntityScan("com.xxx.xxx.model") 
@EnableScheduling
public class BeverageDataServicesApplication {

    public static void main(String[] args) {
        SpringApplication.run(BeverageDataServicesApplication.class, args);
    }
}

It looks like the JRE was removed or not present in the Java Build Path ... thank you both for your quick insight!! I added the Java 8 JRE to the Build Path and it works... thanks
