java - 为什么heroku构建由于gradle和spring boot而失败？

Question

我正在尝试为Spring Boot和Gradle设置基本工作区。
一切在本地和travis中都可以正常运行，但是在heroku中构建失败。我认为问题不在实际代码中，而在配置中。

这是我在github.中的项目

build.gradle

plugins {
    id 'java'
    id 'maven'
    id 'jacoco'
    id 'org.springframework.boot' version '1.5.3.RELEASE'
}

group = 'org.karlin'
version = '0.1.0'

sourceCompatibility = 1.8
targetCompatibility = 1.8

tasks.withType(JavaCompile) {
    options.encoding = 'UTF-8'
}

bootRepackage {
    mainClass = 'gramise.Gramise'
}

repositories {
    maven {
        url("https://plugins.gradle.org/m2/")
    }
}

dependencies {
    compile("com.google.code.gson:gson")
    compile("org.springframework.boot:spring-boot-starter-thymeleaf")
    compile("org.springframework.boot:spring-boot-starter-data-jpa")
    compile("org.postgresql:postgresql")
    compile("org.apache.commons:commons-dbcp2")
    compile("com.h2database:h2")
    testCompile(group: 'org.springframework.boot', name: 'spring-boot-
    starter-test', version:'1.5.3.RELEASE') {
        exclude(module: 'commons-logging')
    }
    testCompile group: 'com.jayway.jsonpath', name: 'json-path', version:'2.2.0'
}

task stage(dependsOn: ['build', 'clean'])
build.mustRunAfter clean

有heroku构建日志

您需要将gradlew检入Git。

WARNING: Your application does not have it's own gradlew file.

因为您没有执行此操作，所以Heroku使用了非常旧的Gradle版本。
