当我使用以下方法执行 jar 时遇到以下错误java -jar .\QuartzScheduler-0.0.1-SNAPSHOT.jar

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

这是我的 build.gradle 的一个片段，请帮助阐明这一点。

构建.gradle

plugins {
    id 'java'
    id 'org.springframework.boot' version '3.3.1'
    id 'io.spring.dependency-management' version '1.1.5'
}

group = 'com.quartz'
version = '0.0.1-SNAPSHOT'

java {
    toolchain {
        languageVersion = JavaLanguageVersion.of(17)
    }
}

repositories {
    mavenCentral()
}

dependencies {
    implementation 'org.springframework.boot:spring-boot-starter-quartz'
    implementation 'org.springframework.boot:spring-boot-starter-web'
    implementation 'org.springframework.boot:spring-boot-starter-jdbc:2.4.1'
    implementation 'org.apache.logging.log4j:log4j-api:2.20.0'

    testImplementation 'org.springframework.boot:spring-boot-starter-test'
    testRuntimeOnly 'org.junit.platform:junit-platform-launcher'
}

tasks.withType(Jar) {
    duplicatesStrategy = DuplicatesStrategy.EXCLUDE

    manifest {
        attributes["Main-Class"] = "com.quartz.QuartzSchedulerApplication"
    }
}

jar {
    enabled = true
    archiveClassifier = ''

    manifest {
        attributes 'Main-Class' : "com.quartz.QuartzSchedulerApplication"
    }

    from {
        configurations.runtimeClasspath.collect {it.isDirectory() ? it : zipTree(it)}
    }
}

tasks.named('test') {
    useJUnitPlatform()
}

QuartzSchedulerApplication.class

package com.quartz.QuartzScheduler;

import com.quartz.QuartzScheduler.model.User;
import com.quartz.QuartzScheduler.repo.UserRepo;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.ApplicationContext;

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;

@SpringBootApplication
public class QuartzSchedulerApplication {

    public static void main(String[] args) {

        try {
            ApplicationContext context = SpringApplication.run(QuartzSchedulerApplication.class, args);


        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

任何帮助都将不胜感激。提前致谢！

我开始使用 Log4j 构建我的 Quartz 项目，并且成功了。此外，我验证了 jar 文件包含我的主类，并且清单文件也存在。当我使用 bootJar 运行应用程序时，它也成功了。我还尝试使用 java -cp .\QuartzScheduler-0.0.1-SNAPSHOT.jar com.quartz.QuartzSchedulerApplication 执行 jar 文件。不确定这是否是由于 JDBC 的实现。
