dependency conflicts spotting

1) preapre raw dependencies
./dependency-list.sh ipflow-parent.pom
./dependency-list.sh link-core-1.3.2.pom

2) compile
javac ConfiltList.java

3) execute
java ConfiltList ipflow-parent.pom.dep.raw flink-core-1.3.2.pom.dep.raw

4) file: dependency-list.sh
#!/bin/sh

POMFILE=$1
#wget http://central.maven.org/maven2/org/apache/flink/flink-core/1.3.2/flink-core-1.3.2.pom

mvn dependency:tree -f $POMFILE > $POMFILE.dep
cat $POMFILE.dep | grep '[INFO]' | awk 'match($0, /\:jar\:.*/) && $0!~"test" {print $0}' | awk -F "- " '{print $2 ":flink-core-1.3.2"}' | sort | uniq > $POMFILE.dep.raw
