Question

我正在使用gradle（4.7版）来编译具有多模块的项目（Java 1.8）：

./gradlew -p web -x test build

其中一个没有dist jar，另一个有问题，编译输出的正常dir结构是什么？

--build
----classes
----libs
----tmp

和异常的目录结构：

--build
----classes
----tmp

这是build.gradle（异常模块）：

project(":monitor-business") {

    description = "business"

    dependencies {
        api project(':data')
        api project(':common')
        implementation('org.springframework.boot:spring-boot-starter-web')
    }
}

PS：所有模块都不生成libs文件夹，libs是缓存。为什么模块不生成dis jar文件，如何配置gradle项目。这是项目的完整配置：

group 'dolphin'
version '1.0-SNAPSHOT'


buildscript {
    ext {
        springBootVersion = '2.1.3.RELEASE'
        springVersion = '4.3.7.RELEASE'
        springfoxVersion = '2.6.1'
        jacksonVersion = '2.8.7'
        lombokVersion = '1.16.14'
    }
    ext['tomcat.version'] = '9.0.16'

    repositories {
        mavenCentral()
        jcenter{
            url 'http://jcenter.bintray.com'
        }
    }

    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")

    }
}

def getVersionCode() {
    def versionFile = file("$rootDir/version.properties")
    if (!versionFile.canRead()) {
        throw new GradleException("Could not find version.properties!")
    }
    def versionProps = new Properties()
    versionProps.load(new FileInputStream(versionFile))
    def versionCode = versionProps['VERSION'].toString()
    return versionCode
}

PS：我的问题就像这样的备忘录：https://discuss.gradle.org/t/gradle-4-x-jar-is-not-generated/24773

我已经解决了，但是不知道为什么。...

要解决此问题，请使用以下命令来构建项目（它将生成libs文件夹和jar文件）：

./gradlew -p web -x test -x jar build

版本版本：4.7。（5.3版不起作用）

gradlew complie没有lib.jar
