Gradle项目错误-java.lang.ClassNotFoundException:org.springframework.boot.SpringApplication [英] Gradle project error - java.lang.ClassNotFoundException: org.springframework.boot.SpringApplication

问题描述

这是我的主要应用代码:

This is my main application code:

package u.d.dip.rs.app;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;

@EnableWebSecurity
@SpringBootApplication
@ComponentScan(basePackages = "u.d.dip")
@EnableAutoConfiguration
public class DipApplication {
    public static void main(String[] args) {
        SpringApplication.run(DipApplication.class, args);
    }
}

我正在使用gradle构建项目.即使SpringApplication文件已正确导入，我也会遇到以下错误:

I'm using gradle to build the project. Even though SpringApplication file is properly imported I'm getting the following error:

Caused by: java.lang.ClassNotFoundException: org.springframework.boot.SpringApplication
    at java.net.URLClassLoader.findClass(URLClassLoader.java:381)
    at java.lang.ClassLoader.loadClass(ClassLoader.java:424)
    at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:331)
    at java.lang.ClassLoader.loadClass(ClassLoader.java:357)
    ... 6 more

Process finished with exit code 1

当我将鼠标悬停在SpringApplication上时，我会收到gradle消息

I'm getting following gradle message when I hover over SpringApplication

[Gradle: org.springframework.boot:spring-boot:1.5.1.RELEASE] org.springframework.boot public class SpringApplication extends Object

任何帮助将不胜感激. 预先感谢！

Any help would be much appreciated. Thanks in advance!

推荐答案

该错误是由于gradle 3.4出现问题，我已将gradle发行版更改为3.2，现在一切正常.

The error was because of an issue with gradle 3.4 I've changed my gradle distribution to 3.2 and everything is working fine now.
