Question:
how to compile cygnus 1.1.0 from sources?

Description:
I follow the guide doing this steps:

git clone https://github.com/telefonicaid/fiware-cygnus.git

cd fiware-cygnus/cygnus-common

mvn clean compile exec:exec assembly:single

cp target/cygnus-common-1.1.0-jar-with-dependencies.jar /usr/cygnus/plugins.d/cygnus/libext

mvn install:install-file -Dfile=/usr/cygnus/plugins.d/cygnus/libext/cygnus-common-1.1.0-jar-with-dependencies.jar -DgroupId=com.telefonica.iot -DartifactId=cygnus-common -Dversion=1.1.0 -Dpackaging=jar -DgeneratePom=false

cp target/classes/cygnus-flume-ng /usr/cygnus/bin/cygnus-flume-ng

cd ../cygnus-ngsi

mvn clean compile exec:exec assembly:single

but in the last step compiling cygnus-ngsi I'm getting the following error:

I installed maven following this guide with the recommended version in the docs(3.2.5) How do I install Maven with Yum?

Flume is already installed from cygnus 0.13 that is what i want to upgrade to 1.1.0

I also tried most of the answers from this topic Maven : error in opening zip file when running maven
