如何为整个Gradle多模块项目只定义一次依赖版本？

我决定从一个城市搬到另一个城市。由于渐变内置BOM导入支持但是

我遇到了这个问题：

我无法在native Gradle中找到替代方案：

    dependencyManagement {
        dependencies {
            dependency("org.springframework:spring-core:4.0.3.RELEASE")
        }
    }
//or
    dependencyManagement {
         dependencies {
              dependencySet(group:'org.slf4j', version: '1.7.7') {
                   entry 'slf4j-api'
                   entry 'slf4j-simple'
              }
         }
    }

然后我可以使用不带版本的依赖关系

dependencies {
    compile 'org.springframework:spring-core'
}

我如何才能在naive Gradle中获得同样的行为？我的意思是：我想定义一个版本一次，就像我在使用下面的解决方案时所做的那样，这有助于避免版本复制粘贴。然而，它与依赖管理插件不同

对于Gradle Kotlin Dsl:

当您可以放置任何常量时，您可以使用自己的代码创建

buildSrc

算法：

创建文件夹

buildSrc/src/main/kotlin

创建包含以下内容的文件

buildSrc/src/main/kotlin/Versions.kt

：

创建包含以下内容的文件

buildSrc/build.gradle.kts

：

在gradle.kts文件中使用以下语法：

对于Gradle Groovy:

创建文件

gradle.properties

将语法类似于

okhttp\u version=4.2.0的版本放在那里

在gradle文件中使用以下语法：

---

您可以在

gradle.properties

文件中执行此操作。即：

# APPLICATION PROPERTIES
name=projectName
group=com.domain
version=1.0.0
description=A brief description

gradleScripts=https://raw.githubusercontent.com/hexagonkt/hexagon/1.2.0/gradle

# DEPENDENCIES VERSIONS
kotlinVersion=1.3.61
kotlinCoroutinesVersion=1.3.2

或者在

settings.gradle

中，如果不想创建另一个文件：

rootProject.name = "hexagon-contact-application"

gradle.rootProject {

    allprojects {
        version = "1.0.0"
        group = "org.hexagonkt"
        description = "Contact application backend api"
    }

    extensions.gradleScripts = "https://raw.githubusercontent.com/hexagonkt/hexagon/1.0.18/gradle"

    extensions.kotlinVersion = "1.3.50"
    extensions.kotlinCoroutinesVersion = "1.3.2"

    extensions.hexagonVersion = "1.0.21"

    extensions.logbackVersion = "1.2.3"
    extensions.bcryptVersion="0.8.0"
    extensions.javaJwtVersion="3.8.2"
}

如果要避免将版本变量添加到所有相关依赖项，可以在生成文件中创建一个方法：

plugins {
    id 'org.jetbrains.kotlin.jvm' version '1.3.50'
}

apply from: "$gradleScripts/kotlin.gradle"
apply from: "$gradleScripts/service.gradle"
apply from: "$gradleScripts/junit.gradle"

defaultTasks("test")

mainClassName = 'com.hexagonkt.contact.ApplicationKt'
applicationDefaultJvmArgs = ["-Xms64M", "-Xmx2G", "-XX:+UseNUMA", "-XX:+UseParallelGC"]

dependencies {
    httpkt(it, "http_server_jetty")
    httpkt(it, "store_mongodb")
    httpkt(it, "hexagon_web")

    implementation("at.favre.lib:bcrypt:$bcryptVersion")
    implementation("com.auth0:java-jwt:$javaJwtVersion")

    testImplementation("com.hexagonkt:port_http_client:$hexagonVersion")
}

private void httpkt(final def dependencies, final String artifact) {
    dependencies.implementation("com.hexagonkt:$artifact:$hexagonVersion")
}

dependencies {
    compile group: 'com.squareup.okhttp3', name: 'okhttp', version: okhttp_version
}

# APPLICATION PROPERTIES
name=projectName
group=com.domain
version=1.0.0
description=A brief description

gradleScripts=https://raw.githubusercontent.com/hexagonkt/hexagon/1.2.0/gradle

# DEPENDENCIES VERSIONS
kotlinVersion=1.3.61
kotlinCoroutinesVersion=1.3.2

rootProject.name = "hexagon-contact-application"

gradle.rootProject {

    allprojects {
        version = "1.0.0"
        group = "org.hexagonkt"
        description = "Contact application backend api"
    }

    extensions.gradleScripts = "https://raw.githubusercontent.com/hexagonkt/hexagon/1.0.18/gradle"

    extensions.kotlinVersion = "1.3.50"
    extensions.kotlinCoroutinesVersion = "1.3.2"

    extensions.hexagonVersion = "1.0.21"

    extensions.logbackVersion = "1.2.3"
    extensions.bcryptVersion="0.8.0"
    extensions.javaJwtVersion="3.8.2"
}

plugins {
    id 'org.jetbrains.kotlin.jvm' version '1.3.50'
}

apply from: "$gradleScripts/kotlin.gradle"
apply from: "$gradleScripts/service.gradle"
apply from: "$gradleScripts/junit.gradle"

defaultTasks("test")

mainClassName = 'com.hexagonkt.contact.ApplicationKt'
applicationDefaultJvmArgs = ["-Xms64M", "-Xmx2G", "-XX:+UseNUMA", "-XX:+UseParallelGC"]

dependencies {
    httpkt(it, "http_server_jetty")
    httpkt(it, "store_mongodb")
    httpkt(it, "hexagon_web")

    implementation("at.favre.lib:bcrypt:$bcryptVersion")
    implementation("com.auth0:java-jwt:$javaJwtVersion")

    testImplementation("com.hexagonkt:port_http_client:$hexagonVersion")
}

private void httpkt(final def dependencies, final String artifact) {
    dependencies.implementation("com.hexagonkt:$artifact:$hexagonVersion")
