错误：为多模块项目创建jar后，找不到或加载主类

Question

我正在使用IntelliJ和gradle创建一个多模块spring项目，如下所示。 在根文件夹中有以下build.gradle，我在下面进行了以下设置。调用gradle build时，将在build / libs中创建一个jar，但是执行该jar会收到错误消息： **错误：找不到或加载主类com.connect.configuration.ConnectApplication **在不通过以下方式构建而运行应用程序时：gradle bootRun-应用程序正确加载。但是，在构建项目后执行jar文件会产生错误，并且jar输出以下内容：使用

jar -tf myJar.jar
META-INF/
META-INF/MANIFEST.MF

plugins {
    id 'io.spring.dependency-management' version '1.0.8.RELEASE'
    id 'java'
}

subprojects {
    group = 'com.connect.connect'
    version = '0.0.1-SNAPSHOT'

    sourceCompatibility = 1.9
    targetCompatibility = 1.9

    apply plugin: 'java'
    apply plugin: 'io.spring.dependency-management'
    apply plugin: 'java-library'

    repositories {
        jcenter()
    }

    dependencies {
        compileOnly 'org.projectlombok:lombok:1.18.10'
        annotationProcessor 'org.projectlombok:lombok:1.18.10'
    }
    dependencyManagement {
        imports {
            mavenBom("org.springframework.boot:spring-boot-dependencies:2.1.9.RELEASE")
        }
    }
}

settings.gradle
