Question

所以我使用Gradle构建了一个spring boot应用程序。它在本地构建和运行时工作正常，但是，我无法在Heroku上运行它。这是日志：

我有这个Procfile：

web: java -jar build/libs/bristech.jar

这是我的gradle.build：

group 'com.bristech'
version '1.0-SNAPSHOT'

apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'idea'
apply plugin: 'org.springframework.boot'

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:1.5.10.RELEASE")
    }
}

repositories {
    mavenCentral()
    maven { url "https://repository.jboss.org/nexus/content/repositories/releases" }
    maven { url 'https://repo.spring.io/libs-snapshot' }
}

jar {
    baseName = 'bristech'
}

task stage {
    dependsOn build
}

sourceCompatibility = 1.8
targetCompatibility = 1.8

dependencies {
    //Spring web, database and security
    implementation("org.springframework.boot:spring-boot-starter-web")
    implementation("org.springframework.boot:spring-boot-starter-data-jpa")
    implementation("mysql:mysql-connector-java:5.1.6")
    implementation 'com.google.firebase:firebase-admin:5.9.0'

    //logging
    implementation("org.apache.logging.log4j:log4j-api:2.10.0")
    implementation("org.apache.logging.log4j:log4j-core:2.10.0")

    testCompile group: 'junit', name: 'junit', version: '4.12'
}

我怀疑错误必须与jar文件有关。我也试过在没有Procfile的情况下运行它，但它仍然无法正常工作。

Answer 1

您应该在Procfile中指定带有版本的jar名称，如下所示。

web: java -jar build/libs/bristech-1.0-SNAPSHOT.jar

Answer 2

显然，问题出在我的gradle.build文件中。我正在使用implementation添加新的依赖项而不是compile。我一改变它就像一个魅力......

我认为implementation是编译的新版本，它将取代它..

Spring无法在Heroku上运行
