我已经尝试了无数的方法来通过IntelliJ中的终端将Maven部署到Heroku。 Heroku不断给我这个消息，我确定它与Procfile＆amp;有关。也许是我的pom.xml。它在本地运行良好
Heroku日志：

我的Procfile：
web: ./build/install/ctr39/bin/ctr39
我整天都在这里复制和操纵

知道我做错了什么吗？它可能与Spark中的端口问题有关，我在我的主文件中复制了提供文档的片段...
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)
}
答案 0 :(得分：1)
在Codefinger的帮助下，我指出了正确的方向......
我更新了我的POM.XML ..我摆脱了web-runner并添加了
<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>
然后将我的Prodfile更改为...
web: java $JAVA_OPTS -cp target/classes:target/dependency/* com.reach.ctr39.App
我保留了Spark文档中的Port功能。感谢你们。希望这可以帮助将来的某个人。

尝试使用以下Procfile文件：
web: java -jar ./target/ctr39-1.0-jar-with-dependencies.jar
而不是ProcessBuilder尝试：
System.getenv('PORT')
