java - 如何在Intellij/Gradle中创建可运行的.jar文件

Question

有人可以告诉我如何使用Intellij和Gradle在cmd中运行.jar文件吗？

我尝试创建 list 文件，但出现错误:

no main manifest attribute, in eureka-server.jar

要么

Error: Could not find or load main class com.project.EurekaServerApplication
Caused by: java.lang.ClassNotFoundException: com.project.EurekaServerApplication

我的主类:

package com.project;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;

@SpringBootApplication
@EnableEurekaServer
public class EurekaServerApplication {

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

在MANIFEST.MF中的路径/ resources / META-INF中

Manifest-Version: 1.0
Main-Class: com.project.EurekaServerApplication

我也在build.gradle中尝试

jar {
    manifest {
        attributes(
                'Main-Class': 'com.project.EurekaServerApplication'
        )
    }
}

我以这种方式运行这个jar文件:

java -jar [nameApplication].jar

为了运行.jar文件，必须在gradle构建之后使其可执行(无论intellij如何)，请在gradle文件中使用bootRepackage task:

bootRepackage {
  mainClass = 'com.project.EurekaServerApplication'
}
