Maven jar dependency issue package not found on OpenShift server

I'm getting a dependency issue with a jar I'm attempting to use. I receive the following error

remote: [ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:2.3.2:compile (default-compile) on project sparq: Compilation failure: Compilation failure:
remote: [ERROR] /var/lib/openshift/55846322500446673d000007/app-root/runtime/repo/src/main/java/ServerQuery.java:[3,0] error: package com.github.koraktor.steamcondenser does not exist
remote: [ERROR] /var/lib/openshift/55846322500446673d000007/app-root/runtime/repo/src/main/java/ServerQuery.java:[8,8] error: cannot find symbol
remote: [ERROR] class ServerQuery
remote: [ERROR] /var/lib/openshift/55846322500446673d000007/app-root/runtime/repo/src/main/java/ServerQuery.java:[8,34] error: cannot find symbol

Here is the offending java file.

package helpers;

import com.github.koraktor.steamcondenser.*;

public class ServerQuery {

    public static String getPlayers() {
        SourceServer server = new SourceServer("66.150.155.152",27015);
        server.initialize();
        return server.toString();
    }
}

I've added the following dependency to my pom.xml

<dependency>                                                                                                    
    <groupId>com.github.koraktor</groupId>                                                                      
    <artifactId>steam-condenser</artifactId>                                                                    
    <version>1.3.9</version>
</dependency>

I've also added the following action_hook pre_build script

mvn install:install-file -Dfile=./app-root/repo/steam-condenser.jar -DgroupId=com.github.koraktor -DartifactId=steam-condenser -Dversion=1.3.9 -Dpackaging=jar

Here's the GitHub for the project https://github.com/koraktor/steam-condenser-java And the website for it http://koraktor.de/steam-condenser/usage/

Any ideas? Completely lost. Help much appreciated.

Just by looking at the question and the excerpts provided, I believe you are struggling with the basics of Maven. If I understand the situation correctly you have a library (which is not written by you):

  • once added to your project as a Maven dependency. This seems reasonable if you want to use it.

  • once the source code of the library incorrectly added to your own Java project.

    remote: [ERROR] /var/lib/openshift/55846322500446673d000007/app-root/runtime/repo/src/main/java/ServerQuery.java:[3,0] error: package com.github.koraktor.steamcondenser does not exist

Based on the errormessage above it seems you have copied one of the sourcefiles from the library into your project. This is now causing problems. The main one is that without your source-folder (src/main/java) correctly representing the package structure declared in the source file (com.github...) it cannot be compiled. Hence the errormessage:

package com.github.koraktor.steamcondenser does not exist.

First of all you need to remove this copy-pasted file entirely an just use the dependency-management feature of Maven to get the library on classpath. After that just follow the examples given by the author of the library using the link you have already found (http://koraktor.de/steam-condenser/usage/).

Since you are including the jar file in your project already, trying to manage the dependency with Maven seems like overkill. You should be able to put the jar file in your project's lib directory like this article describes. Then you won't need to configure that dependency in Maven at all.

I would use Maven for any dependencies that you want to download at the time your application is being built. Any jar files that you are checking into your project shouldn't need to be configured in Maven.
