Java 几个带渐变和弹簧的模块

我正在尝试使用Spring boot插件清理构建项目，并得到以下消息：

任务“：讲师05:findMainClass”的执行失败。 无法从以下候选对象中找到单个主类[ru.atom.boot.mm.MatchMakerApp，ru.atom.boot.hw.HelloSpringBoot]

我找不到关于这个案子的任何信息。我发现了几个问题，比如，但这是给maven的。如何正确配置我的项目？
我想补充一下

bootRepackage {
    mainClass = 'ru.atom.boot.mm.MatchMakerApp'
}

到

build.gradle

我的根项目：

plugins {
id 'org.springframework.boot' version '1.5.8.RELEASE'
id 'com.github.kt3k.coveralls' version '2.6.3'
}

bootRepackage {
mainClass = 'ru.atom.boot.mm.MatchMakerApp'

子项目，我正在尝试构建，它有两个主要类：

dependencies {
compile rootProject.libraries.spring_boot
compile rootProject.libraries.log4j


testCompile rootProject.libraries.junit
testCompile rootProject.libraries.spring_boot_test
}

sourceSets {
main {
    java {
        srcDirs = ['src/main/java']
    }
}
test {
    java {
        srcDirs = ['src/test/java']
    }
}
}

尝试将其替换为：

springBoot {
    mainClass = 'ru.atom.boot.mm.MatchMakerApp'
}

如前所述，您可以在Spring Boot plugin中阅读更多内容

pom文件中的起始类是什么？还是在org.springframework.boot插件中定义主类？@jprismupdated@jprism这就是我试图定义的主要内容class@jprism实际上，我现在要添加build.gradle。Try:springBoot{mainClass='ru.atom.boot.mm.MatchMakerApp'}
