spring – Gradle build不会向包中添加版本

我正在使用带有Gradle 4.2的Spring Boot 2.0.0.M7创建一个REST微服务.
当我从Eclipse构建或从控制台./gradlew构建运行时,build / libs中生成的包被命名为$app.jar而不是$app- $version.jar.

我错过了什么？我的build.gradle与Spring Boot Docker GS指南相同,这个问题阻止了生成docker镜像,因为无法找到jar.

这是我的build.gradle文件：

buildscript {
    ext {
        springBootVersion = '2.0.0.M7'
        springCloudVersion = 'Finchley.M5'
        gradleDockerVersion = '0.13.0'
    }
    repositories {
        mavenCentral()
        maven { url 'https://plugins.gradle.org/m2/' }
        maven { url 'https://repo.spring.io/snapshot' }
        maven { url 'https://repo.spring.io/milestone' }
        maven { url 'https://repo.spring.io/libs-milestone' }
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
        classpath("gradle.plugin.com.palantir.gradle.docker:gradle-docker:${gradleDockerVersion}")
    }
}

apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'com.palantir.docker'
apply plugin: 'org.springframework.boot'
apply plugin: 'io.spring.dependency-management'

    baseName = 'networks'

}
