Adding Maven Plugins
Hi,
I'm new to using Maven. I purchased the book, "Maven A Developer's
Nnotebook", and I've read it cover to cover. However, it's not up to
date with Maven2. I've setup my first Maven project and now I'm
trying to download a few Maven plugins. Initially I need to download
the Spring1.2.6.jar and the latest Hibernate jar. I've been trying
for the last four hours or so to figure out how to do this to no
avail.
Could someone please explain the steps I need to take in order to do
this? For example, what are the steps I need to take in order to
download the latest spring core jar?
Thanks in advance for the help.

Thanks for all of the help. I'm starting to get the hang of Maven 2.

Just to add a little bit of info on this, when you specify a plugin in
your pom, you do it in the <build> section. It has one main purpose -
configuring the plugin use. You don't need to specify every plugins
you use if you use the default configuration values, Maven 2 is able
to figure it out by itself. So don't worry about it for the moment.
People are a bit scared at first because Maven 2 is pretty smart and
rely on the "Convention over configuration" principle. Have fun!

A dependency is "something your project needs during compilation,
testing, or runtime".
A plugin is "something you want Maven to run during compilation,
testing, packaging, etc to do *something* to your project/code".
So your project might have a *dependency* on spring core.
And it might use the *plugin* axistools-maven-plugin to generate WSDL
out of your Java, or Java out of your WSDL.
And it might use the *report* javancss-maven-plugin to report on lines
of code in your project etc.
I have to imagine this is all covered in the M2 book mentioned
previously. Can't quote a specific page though... So keep reading. ;-)

The default location of your local repository is <home
directory>/.m2/repository, and you can walk the tree there to see what
has been downloaded. <home directory> in Windows XP is typically
c:\documents and settings\<username>.
You should also try running mvn with the -X option, which prints out
debug information and makes the process easier to understand. For
example: mvn -X jar:jar

So, I'm the one who added the dependency to my pom. However, when I
executed the command, mvn jar:jar, I did not see any messages that it
was downloading the spring core plugin. So, I have two questions:
1) Where can I look to verify that the plugin has been downloaded?
2) What's the difference in defining a plugin as apposed to a dependency?
Thanks.

No good. I've known too many Spaniards.

Re: Adding Maven Plugins
Posted by Hycel Taylor <hy...@gmail.com>.
I'm pretty confused from what I have read:
I do not understand if I should be adding a dependency or a plugin.
This is what I currently have in my pom file:
<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/maven-v4_0_0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>com.acme.app</groupId>
<artifactId>acme1.0</artifactId>
<packaging>jar</packaging>
<version>1.0-SNAPSHOT</version>
<name>Maven Quick Start Archetype</name>
<url>http://maven.apache.org</url>
<dependencies>
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>3.8.1</version>
<scope>test</scope>
</dependency>
<!-- Do I add spring as a dependency? -->
<dependency>
<groupId>spingframework</groupId>
<artifactId>spring-core</artifactId>
<version>1.2.6</version>
</dependency>
</dependencies>
</project>
In the book, Better Builds With Maven, section 2.7 describes getting a
plugin with the <plugins><plugin> elements. However, the dtd, does
not allow a <plugins> element. It does however allow for
<pluginRepositories><pluginRepository> elements.
I would like to get the spring core jar plugin to work. Can any one
provide a solution the I can add to my pom file?
Thanks in advance

If you want to get updated on Maven 2, I can highly recommend the new
book "Better Builds with Maven" written by some of the Maven
contributors. It is available as a free download from this site
(registration is required)

You shouldn't have to download anything manually - Maven should do it
for you. But for this to happen you need to set up your dependencies
correctly. Here's an introduction to how dependencies work:
