Please, ANSWER this question AT http://stackoverflow.com/questions/37680260/how-to-compile-cygnus-1-1-0-from-sources-and-update-cygnus-0-13

Question:
how to compile cygnus 1.1.0 from sources and update cygnus 0.13?

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

Edit 1 (compiling cygnus-common)

[root@PAPELclub-VM014cen-Prod cygnus-common]# mvn clean compile exec:exec assembly:single

y el resultado en target:

I don't know why is terminating it I already give more memory to de jvm of maven as the documentation said:

export MAVEN_OPTS="-Xmx512m -XX:MaxPermSize=128m"

Edit 2
With the compiled files in the right places

/usr/cygnus/plugins.d/cygnus/lib/cygnus-ngsi-1.1.0-jar-with-dependencies.jar
/usr/cygnus/plugins.d/cygnus/libext/cygnus-common-1.1.0-jar-with-dependencies.jar
/usr/cygnus/bin/cygnus-flume-ng

all with the correct rights (777) I'm getting the following error when running with this command:

1. timeout for batch accumulation
   cygnusagent.sinks.ckan-sink.batch_timeout = 60

1. number of retries upon persistence error
   cygnusagent.sinks.ckan-sink.batch_ttl = 10

How should I update the 0.13 version? should I uninstall cygnus 0.13 and do it on a clean flume? will be released a yum install package like with the cygnus 0.13 version?
