springBoot2.0 gradle 多模塊項(xiàng)目打包問題。

項(xiàng)目是用springBoot+gradle生成的，后來改成了多模塊，結(jié)果打包的時(shí)候報(bào)錯(cuò)：The value of a manifest attribute must not be null (Key=Start-Class)
這個(gè)start-class應(yīng)該就是springboot啟動(dòng)的application類，不知道是不是因?yàn)槲腋某闪硕嗄K項(xiàng)目，gradle配置文件沒寫好，所以導(dǎo)致拿不到start-class。

以下是build.gradle文件（springboot版本原本是2.0.0 M7，后來改成了2.0.1.BUILD-SNAPSHOT）：

apply from: "./libraries.gradle"

buildscript {
    ext {
        springBootVersion = '2.0.1.BUILD-SNAPSHOT'
        mybatisGeneratorVersion = '1.4'
    }
    repositories {
        mavenCentral()
        maven { url "https://repo.spring.io/snapshot" }
        maven { url "https://repo.spring.io/milestone" }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
    }
}

apply plugin: 'java'

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

/*group = 'com.psy'

/*repositories {
    mavenCentral()
    maven { url "https://repo.spring.io/snapshot" }
    maven { url "https://repo.spring.io/milestone" }
}*/

//configuration for all projects
allprojects {
    apply plugin: 'java'
    group 'com.psy'
    version = '0.0.1-SNAPSHOT'
    sourceCompatibility = 1.8
    targetCompatibility = 1.8

    repositories {
        mavenCentral()
        maven { url "https://repo.spring.io/snapshot" }
        maven { url "https://repo.spring.io/milestone" }
    }

    /*jar {
        enabled = true
        baseName = 'psy'
        version = '0.5.0'
        manifest {
            attributes "Manifest-Version": 1.0,
                       'Main-Class': 'org.springframework.boot.loader.JarLauncher',
                    'Start-Class': 'com.psy.metrics.MetricsApplication'
        }
    }*/

    /*bootJar {
        classifier = 'app'
        baseName = 'psy'
        version = '0.5.0'
        manifest {

    }*/
}

//find out the java projects
ext.javaProjects = subprojects.findAll { project -> project.name != 'docs' && project.name != 'manual' && project.name != 'guides'}

    }
}

settings.gradle：
rootProject.name = 'metrics'
include 'web'
include 'service'

include 'common'

報(bào)錯(cuò)信息：

有試過在build.gradle里面覆蓋bootJar的命令，把start-class強(qiáng)行寫上去，雖然能生成jar包，但是并不完整。

求大神們指出一下是哪里出了問題，需要怎么改，萬分感謝T T
