Apache Maven

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

Build EJB JAR with maven

   1 mvn clean compile package

In http://localhost:8080/admin-console/ at link EJB 3.x Application (EJB JAR), add resource test2-0.0.1.jar.

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
jbossws-native-jaxrpc.jar
jbossws-native-jaxws.jar
jbossws-native-jaxws-ext.jar

Check deployed EJB with http://localhost:8080/test2-0.0.1/WSTest?wsdl
