image - Building fiware/cygnus docker from source code - issue with the last step (8) -

-

when trying build fiware/cygnus docker image source code, last part of it, namely building of image jar with: 

docker build -f ./docker/dockerfile -t fiware/cygnus .

gives following message in last step (8) of building process: "no source files specified". @ point building appears aborted.

the building done according: https://github.com/telefonicaid/fiware-cygnus/tree/master/docker (source code from: https://github.com/telefonicaid/fiware-cygnus.git ), , amounts first building java archive (jar) provided source code, , subsequently building docker image jar file.

1) reason message in step 8? since, according documentation, no other steps mentioned. also, "target" directory, mentioned in documentation, appears not made.

2) however, there appear image, no tags (cf "-t fiware/cygnus" flag in command mentioned above). result fact building done step 8, leaving incomplete image?

many thanks!

step 8 is

step 8 : add ./target/*.jar /tmp/

this means haven't had success building jar.

replicating steps current head 2a9c87fb7fd6156225e2eed7fbc9792f1d9c5dfe gave me errors, attributed java_home variable not set.

please, implement following changes in dockerfiles until merge master:
