Review comment:
Sure. It's a good question.
Until now we used wildcard in the docker-compose.yaml to define the
classpath, independent from the current version:
```
HADOOP_CLASSPATH:
/opt/ozone/share/ozone/lib/hadoop-ozone-filesystem-lib-current*.jar
```
Unfortunately it didn't work all the time. When I executed a command from
the container (after `docker-compose exec scm`) the jar file is not added to
the classpath.
I modified the docker-compose file to use the exact jar file. To make it
version independent instead of the simple copy I replace the current version
with maven (filtering) and copy to preprocessed version to the final
destination with dist-layout-stitching script.
Old version: src/main/compose ---[copy with dist-layout-stitching]--->
destination dir
New version: src/main/compose ---[copy and replace version with maven]--->
target/compose ---[dist layout stiching] --> destination dir
