“NetBeans Platform Development with Maven 2”, by Emilian Bold

[Mike Amanti]

Emilian Bold:

I downloaded and installed JDK 6u6 with NetBeans 6.1 (the Java SE Development Kit 6u6 with NetBeans IDE 6.1 Bundle ) from here… http://java.sun.com/javase/downloads/netbeans.html

Next, I Downloaded and installed “Java EE (5) + Tools” defaulted to the existing Java SE directory “JDK_6u6_and_NB_6.1”… from here http://java.sun.com/javaee/downloads/index.jsp

Thirdly, I used the Netbeans website http://www.netbeans.org/index.html search mechanism and searched for “Maven 2” and found…

    NetBeans Platform Development with Maven 2
     http://www.netbeans.org/community/magazine/html/04/maven.html

3.A) I followed the above development with Maven 2 procedures and created a project: file | new project | maven and the although the build included an error while “Starting Jakarta Velocity v1.4”, "Velocity successfully started" and resulted in "BUILD SUCCESSFUL".

3.B) Next, again, following the development procedure, I Changed the packaging (from jar) to nbm and tried to build the project… and that resulted in "BUILD SUCCESSFUL"

3.C) Next, again, following the development procedure, I Added the nbm-maven-plugin and did a Clean & Rebuild and this resulted in “BUILD SUCCESSFUL” resulted.

So far so good.

3.D) Next, again, following the development procedure, "Run The Project".
“You might get errors related to Windows paths while trying to run the project.
Make sure you don’t have spaces in these paths, as these are usually the culprits.”

NOTE: My NetBeans Project Window did not even show a directory for
"Other Sources" as depicted in the development procedure.
Perhaps this is the first sign of real trouble.

When I ran the project, "ERROR"s resulted as follows…
=====================================

===========================================

The obvious question is...
Given that I have followed the development procedure,
What is causing the ERRORs?

NOTE: In the project's properties wizard,
I selected "actions" and then checked the checkbox associated with
“Use External Maven for Build Executiuon”…  same results.
