Document how to add dependency jars for Java Microprofile stack

[mtamboli]

For Liberty applications which are referencing DB2 jars in server.xml file, there is no easy way to copy those files to container image. There is a way to do this by updating generated application pom file. This can be time consuming to figure out so best to document.

I can certainly see this going into Java MicroProfile guide but not sure if other docs can use it too.

<dependency>
     <groupId>com.microsoft.sqlserver</groupId>
     <artifactId>mssql-jdbc</artifactId>
     <version>6.4.0.jre8</version>
    </dependency>      
...

     <plugin>
      <groupId>org.apache.maven.plugins</groupId>
      <artifactId>maven-dependency-plugin</artifactId>
      <version>3.0.1</version>
      <executions>
          <execution>
              <id>copy-resource</id>
              <phase>package</phase>
              <goals>
                  <goal>copy-dependencies</goal>
              </goals>
              <configuration>
               <stripVersion>true</stripVersion>
               <outputDirectory>/project/user-app/target/liberty/wlp/usr/servers/defaultServer/resources/sqljars/</outputDirectory>
               <includeArtifactIds>mssql-jdbc</includeArtifactIds>
              </configuration>
          </execution>
      </executions>
     </plugin>

It is related to Service binding worked by Arthur and Kyle.

For this issue we simply wanted to get an example of how to do this kind of thing out there as an example for people who are trying this out.

There is a larger design discussion to be had around making this easier, which should be contained in kabanero-io/collections#160

If this is covering how to do this today using maven dependencies then the documentation should be requested from the owner of the java-microprofile Appsody stack.

[mtamboli]

I think this should be assigned to YK Chang.

@marikaj123 This is not a collections issue so I have removed myself as owner. This needs assigning to the team who own the java-microprofile stack, I believe, as was noted in the previous two comments, that YK Chang (@yeekangc) is a good starting point.

I see at least 2 parts to this:

1. Document the how today i.e. what has been done. Perhaps @mtamboli and team can help working with the right Docs person (in a guide or whatever appropriate).

2. Longer term answer on how all these should fit together from the container image up to the template, the stack and the collection. I can see gaps to close and integration issues to work out and may relate to the Service Binding work mentioned above. Can file an issue under Appsody stack repo for this.

FYI, @scottkurz.

@yeekangc - any idea who need to work on this issue beside an ID person?
