mvn compile fails on my machine - dependancy issues ..

[davidbalme]

This project looks very intriguing .. Having build issues tho' :-)

Did a git clone of this project .. from my ubuntu machine ..
java version..
ubuntu@ubuntu-Latitude-E6440:/tmp/converter-page$ java -version
openjdk version "1.8.0_162"
OpenJDK Runtime Environment (build 1.8.0_162-8u162-b12-114.04-b12)
OpenJDK 64-Bit Server VM (build 25.162-b12, mixed mode)

on mvn clean compile I get failure - as follows

[ERROR] Failed to execute goal on project java-converter: Could not resolve dependencies for project de.aschoerk.java-converter:java-converter:war:1.0-SNAPSHOT: The following artifacts could not be resolved: com.github.javaparser:javaparser-core:jar:2.4.1-SNAPSHOT, org.apache.maven.doxia:doxia-converter:jar:1.3-SNAPSHOT, org.apache.maven.doxia:doxia-sink-api:jar:1.8-SNAPSHOT, org.apache.maven.doxia:doxia-logging-api:jar:1.8-SNAPSHOT, org.apache.maven.doxia:doxia-test-docs:jar:1.8-SNAPSHOT, org.apache.maven.doxia:doxia-core:jar:1.8-SNAPSHOT, org.apache.maven.doxia:doxia-core:jar:tests:1.8-SNAPSHOT, org.apache.maven.doxia:doxia-module-apt:jar:1.8-SNAPSHOT, org.apache.maven.doxia:doxia-module-confluence:jar:1.8-SNAPSHOT, org.apache.maven.doxia:doxia-module-docbook-simple:jar:1.8-SNAPSHOT, org.apache.maven.doxia:doxia-module-fml:jar:1.8-SNAPSHOT, org.apache.maven.doxia:doxia-module-fo:jar:1.8-SNAPSHOT, org.apache.maven.doxia:doxia-module-latex:jar:1.8-SNAPSHOT, org.apache.maven.doxia:doxia-module-itext:jar:1.8-SNAPSHOT, org.apache.maven.doxia:doxia-module-rtf:jar:1.8-SNAPSHOT, org.apache.maven.doxia:doxia-module-twiki:jar:1.8-SNAPSHOT, org.apache.maven.doxia:doxia-module-xdoc:jar:1.8-SNAPSHOT, org.apache.maven.doxia:doxia-module-xhtml:jar:1.8-SNAPSHOT: Could not find artifact com.github.javaparser:javaparser-core:jar:2.4.1-SNAPSHOT

Is there something I'm doing wrong -or just plain forgetting? .. haven't yet bothered to change pom.xml to modify versions on dependencies .. Would like to avoid that if possible ..

Any ideas?
