Maven Dependency Issue: Could not resolve dependencies for project - maven

Question

I'm having an issue with the github CLIFF repository building a Tomcat .war.
https://github.com/c4fcm/CLIFF
David-Laxers-MacBook-Pro:CLIFF davidlaxer$ java -version
java version "1.8.0_05"
Java(TM) SE Runtime Environment (build 1.8.0_05-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.5-b02, mixed mode)
David-Laxers-MacBook-Pro:CLIFF davidlaxer$ mvn -version
Apache Maven 3.2.1 (ea8b2b07643dbb1b84b6d16e1f08391b666bc1e9; 2014-02-14T09:37:52-08:00)
Maven home: /Users/davidlaxer/Downloads/apache-maven-3.2.1
Java version: 1.8.0_05, vendor: Oracle Corporation
Java home: /Library/Java/JavaVirtualMachines/jdk1.8.0_05.jdk/Contents/Home/jre
Default locale: en_US, platform encoding: UTF-8
OS name: "mac os x", version: "10.10.5", arch: "x86_64", family: "mac"
David-Laxers-MacBook-Pro:CLIFF davidlaxer$
The project builds (e.g. - mvn package) in the CLIFF parent:
E.g.
[INFO] Reactor Summary:
[INFO]
[INFO] CLIFF ............................................. SUCCESS [ 0.003 s]
[INFO] common ............................................ SUCCESS [ 2.854 s]

[INFO] cliff ............................................. SUCCESS [ 18.804 s]
[INFO] ------------------------------------------------------------------------
[INFO] BUILD SUCCESS
[INFO] ----------------------------------------------------------------
It gets a dependency error in the child:
e.g stanford-entity-extractor:

[INFO] ------------------------------------------------------------------------
[INFO] BUILD FAILURE

I don't see .jar for stanford-entity-extractor:jar:2.3.0 here:
http://mvnrepository.com/artifact/edu.stanford.nlp/stanford-corenlp
or here:

Maven then gets an error in the CLIFF parent build building Tomcat:

Answer 1

Looks like stanford-entity-extractor and common are submodule jars that aren't available locally or publicly. If you haven't run mvn install their jars will not have been installed in your local repo yet, so they will be unresolvable.
