= Apache Maven =
Maven is a software project management and comprehension tool.
Based on the concept of a Project Object Model (POM), Maven can
manage a project's build, reporting and documentation from a
central piece of information.

Requires Java.

== Lifecycles and phases ==
 * https://maven.apache.org/guides/introduction/introduction-to-the-lifecycle.html#Lifecycle_Reference


=== Clean Lifecycle ===
 * pre-clean: execute processes needed prior to the actual project cleaning
 * clean: remove all files generated by the previous build
 * post-clean: execute processes needed to finalize the project cleaning

=== Default Lifecycle ===
 * validate: validate the project is correct and all necessary information is available.
 * initialize: initialize build state, e.g. set properties or create directories.
 * generate-sources: generate any source code for inclusion in compilation.
 * process-sources: process the source code, for example to filter any values.
 * generate-resources: generate resources for inclusion in the package.
 * process-resources: copy and process the resources into the destination directory, ready for packaging.
 * compile: compile the source code of the project.
 * process-classes: post-process the generated files from compilation, for example to do bytecode enhancement on Java classes.
 * generate-test-sources: generate any test source code for inclusion in compilation.
 * process-test-sources: process the test source code, for example to filter any values.
 * generate-test-resources: create resources for testing.
 * process-test-resources: copy and process the resources into the test destination directory.
 * test-compile: compile the test source code into the test destination directory
 * process-test-classes: post-process the generated files from test compilation, for example to do bytecode enhancement on Java classes.
 * test: run tests using a suitable unit testing framework. These tests should not require the code be packaged or deployed.
 * prepare-package: perform any operations necessary to prepare a package before the actual packaging. This often results in an unpacked, processed version of the package.
 * package: take the compiled code and package it in its distributable format, such as a JAR.
 * pre-integration-test: perform actions required before integration tests are executed. This may involve things such as setting up the required environment.
 * integration-test: process and deploy the package if necessary into an environment where integration tests can be run.
 * post-integration-test: perform actions required after integration tests have been executed. This may including cleaning up the environment.
 * verify: run any checks to verify the package is valid and meets quality criteria.
 * install: install the package into the local repository, for use as a dependency in other projects locally.
 * deploy: done in an integration or release environment, copies the final package to the remote repository for sharing with other developers and projects.

=== Site Lifecycle ===
 * pre-site: execute processes needed prior to the actual project site generation
 * site: generate the project's site documentation
 * post-site: execute processes needed to finalize the site generation, and to prepare for site deployment
 * site-deploy: deploy the generated site documentation to the specified web server

== Slackbuild ==

You can specify your user configuration in ${user.home}/.m2/settings.xml.
The default location of your local repository is ${user.home}/.m2/repository/.

== Maven sample web app for JBoss AS 7.1.1 ==

=== Web application creation ===
{{{#!highlight sh
cd ~
mvn archetype:generate -DgroupId=org.allowed.bitarus -DartifactId=WebApp -DarchetypeArtifactId=maven-archetype-webapp -DinteractiveMode=false
cd WebApp
mvn clean
mvn compile
mvn package
}}}

Sample WebApp file with source code to use MySQL data source:[[attachment:WebApp.zip]]

Sample WebAppJersey2, with dependencies for Jersey2 and JSON, to be deployed on Tomcat 7:[[attachment:WebAppJersey2.zip]]

=== Deploy web application on jboss AS 7.1.1 ===
{{{#!highlight sh
/opt/jboss-as-7.1.1.Final/bin/standalone.sh 
# http://localhost:9990
# admin 12345678
# Manage deployments
# Add content
# Choose file ~/WebApp/target/WebApp.war
# next, save
# enable , confirm
# http://localhost:8080/WebApp/
}}}

=== Add REST and servlet support ===
 * url http://localhost:8080/WebApp/rest/testSvc/paramx

Add dependencies to pom.xml, jboss AS 7.1.1 JAX-RS
{{{#!highlight xml
<dependency>
    <groupId>org.jboss.resteasy</groupId>
    <artifactId>resteasy-jaxrs</artifactId>

In JBoss 5.1.0 copy the following libraries from the JBOSS_HOME/client directory to the JBOSS_HOME/lib/endorsed directory,  
so that the JAX-WS 2.0 apis supported by JBossWS are used:
 * jbossws-native-saaj.jar
