Java Spring MVC can't start app on Heroku. Error H10 (can't find webapp runner)

Question

I am trying to run my app on Heroku but it doesn't work. From logs I can see the below:

2016-01-18T13:38:31.621218+00:00 heroku[web.1]: Process exited with status 1 2016-01-18T13:38:48.101117+00:00 app[web.1]: Error: Unable to access jarfile target/dependency/webapp-runner-8.0.30.1.jar

2016-01-18T13:38:48.100249+00:00 app[web.1]: Setting JAVA_TOOL_OPTIONS defaults based on dyno size. Custom settings will override them.

2016-01-18T13:38:48.700243+00:00 heroku[web.1]: State changed from starting to crashed 2016-01-18T13:43:12.241285+00:00 heroku[router]: at=error code=H10 desc="App crashed" method=GET path="/" host=macfol.herokuapp.com request_id=c6418015-843d-4f5a-8dde-83130e94a7c6 fwd="159.220.74.5" dyno= connect= service= status=503 bytes=

I have been unsuccessfully trying to modify both pom.xml as well as procfile in order that Heroku will finally find that .jar.

There is the procfile:

web:    java $JAVA_OPTS -jar target/dependency/webapp-runner-8.0.30.1.jar --target/kamienica

And the pom.xml

The "missing" jar can be found in maven dependencies.

Appreciate your help

EDIT The procfile is now:

web: java $JAVA_OPTS -jar target/dependency/webapp-runner.jar --port $PORT target/kamienica.war

No result...

EDIT 2

There is some progress as it crashes elsewhere ;)

EDIT 3 It's working! Thank you all for making this possible. Finally my app is there. It took me 12 months to reach this point. Thank you again! :)

First Remove the start <pluginManagement> and end <pluginManagement/> tags in pom.xml (Do not delete the content inside it). By including this, the dependency directory and the webapp-runner-8.0.30.1.jar will not be created and the application is getting crashed when executing the java command.
Change the finalName tag to <finalName>kamienica</finalName> . Right now you have the capital letter(K) in the <finalName>...</finalName> tag. Change it to small letter as you named it in web: java $JAVA_OPTS -jar target/dependency/webapp-runner.jar --port $PORT target/kamienica.war

Change the name to <warName>kamienica</warName> in maven-war-plugin plugin

           <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-war-plugin</artifactId>
                <version>2.6</version>
                <configuration>
                    <warSourceDirectory>src/main/webapp</warSourceDirectory>
                    <warName>kamienica</warName>
                    <failOnMissingWebXml>false</failOnMissingWebXml>
                </configuration>
            </plugin>

Thank you!!! It's working. 12 months of developing my first app and now it's there! Thank you!! — Maciej, Jan 19 '16 at 14:10

Your destFileName is webapp-runner.jar but your referencing to another jar in your Procfile:

web:    java $JAVA_OPTS -jar target/dependency/webapp-runner-8.0.30.1.jar --target/kamienica
                                              ^^^^^^^^^^^^^^^^^^^^^^^^^^^
                                                 Version is redundant

Use this instead:

web: java $JAVA_OPTS -jar target/dependency/webapp-runner.jar --port $PORT target/Kamienica.war

`Kamienica` in `kamienica.war` should be starts with a uppercase letter – Ali Dehghani Jan 19 '16 at 12:14
As @TimeTravel said, remove the `pluginManagement` tags – Ali Dehghani Jan 19 '16 at 12:45
