Spring boot 在Heroku上未运行Spring boot

因此，我用Gradle构建了一个spring引导应用程序。 在本地构建和运行时，它工作得很好，但是，我不能让它在Heroku上运行。以下是日志：

我有一个文件：

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'
}

我怀疑这个错误与jar文件有关。我也尝试过在没有Procfile的情况下运行它，但是它仍然不起作用。

您应该在Procfile中指定jar名称和版本，如下所示

---

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

显然，问题出在我的gradle.build文件中。 我使用

implementation

来添加新的依赖项，而不是

compile

。 我一改，它就很有魅力

---

我认为

implementation

是compile的新版本，它将取代它

我认为本地运行是指从目标文件夹运行。将jar复制到其他地方并运行，我怀疑这不会起作用，因为jar没有必需的依赖项（因此类未找到异常）。如果你看到了这个问题，试着用spring启动插件创建胖jar。@最好在本地运行，我的意思是我可以用IntelliJ来构建它，但是当我把它推到Heroku时，它构建起来还是不一样的。我不认为这是问题所在，只是不知道该怎么识别这些类。
