Also, we hope to have all these maven issues worked out soon in 4.3

Hi Noah,
In addition to what Brian suggested, one other thing:
B) Alternatively, if you want to build a executable jar or just dump all the
dependencies into a directory
You can also use "mvn dependency:copy-dependencies" to dump all the
dependencies into the target/dependency directory, for easy access.

Build works great, but I am trying to resolve dependencies to this installation
locally with another package, and I am running into problems. I am using one of
the basic netCDF-Java examples from the netCDF-Java website. This is the
pom.xml file I am using to compile, while successfully resolves the netCDF-Java
dependency:
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0
http://maven.apache.org/xsd/maven-4.0.0.xsd";>
<modelVersion>4.0.0</modelVersion>
<groupId>test</groupId>
<artifactId>test</artifactId>
<packaging>jar</packaging>
<version>0.1</version>
<name>test</name>
<dependencies>
<dependency>
<groupId>edu.ucar</groupId>
<artifactId>netcdf</artifactId>
<version>4.3.8-SNAPSHOT</version>
</dependency>
</dependencies>
</project>
However, when I try to run the example program,
$ java -cp target/test-0.1.jar Test
Exception in thread "main" java.lang.NoClassDefFoundError:
ucar/ma2/InvalidRangeException
And so on. Is there a way to include all of these sub-dependencies
automatically, given that I already included netcdf?
Yes,
---- THE SHORT ANSWER:
To get a classpath with all the dependencies for your project run:
mvn dependency:build-classpath
---- THE LONG ANSWER
A) You can also just use Maven to run your test program. Here's some examples:
1) Without args
mvn exec:java -Dexec.mainClass="Test"
2) With args
mvn exec:java -Dexec.mainClass="Test" -Dexec.args="foo bar"
3) With runtime dependencies in the CLASSPATH
mvn exec:java -Dexec.mainClass="Test" -Dexec.classpathScope=runtime
B) Alternatively, if you want to build a executable jar or just dump all the
dependencies into a directory, you should take a look at maven's assembly
plugin. There's an example assembly descriptor at
http://code.google.com/p/vcr4j/source/browse/trunk/src/main/assembly/download-bundle.xml
C) Finally, If you just want to see what dependency's are used by your project
run:
mvn dependency:tree
Cheers
