Heroku构建后，Spark应用程序立即崩溃

Question

I have tried countless methods to get a spark app deployed to Heroku with Maven through the terminal in IntelliJ. Heroku keeps giving me this message and I'm sure it has something do with the Procfile & maybe my pom.xml. It runs fine locally

Heroku logs :

2018-01-24T21:36:14.000000+00:00 app[api]: Build succeeded

my Procfile :

web: ./build/install/ctr39/bin/ctr39

I have been copying and manipulating here all day

Any idea what I'm doing wrong? It likely has something to do with the ports issue in Spark and I copied the snippet in my main file the docs provided ...

static int getHerokuAssignedPort() {
        ProcessBuilder processBuilder = new ProcessBuilder();
        if (processBuilder.environment().get("PORT") != null) {
            return Integer.parseInt(processBuilder.environment().get("PORT"));
        }
        return 4567; //return default port if heroku-port isn't set (i.e. on localhost)
    }

Answer 1

With the help of Codefinger above pointing me in the right direction...

I updated my POM.XML .. I got rid of web-runner and added

<build>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-dependency-plugin</artifactId>
                <version>3.0.1</version>
                <executions>
                    <execution>
                        <id>copy-dependencies</id>
                        <phase>package</phase>
                        <goals><goal>copy-dependencies</goal></goals>
                    </execution>
                </executions>
            </plugin>
        </plugins>
    </build>

and then changed my Prodfile to ...

web: java $JAVA_OPTS -cp target/classes:target/dependency/* com.reach.ctr39.App

I kept the Port function the same from the Spark documents. Thank you guys. Hope this helps someone in the future.

Try using the following Procfile file:

web: java -jar ./target/ctr39-1.0-jar-with-dependencies.jar

And instead of ProcessBuilder try:

System.getenv('PORT')
