When you run a command such as mvn [phase] , Maven will execute all phases from validate to the specified [phase]
-D option is to send parameter value to the pom, or to override the values in ~/.m2/settings.xml.
$ mvn exec:exec -DcustomerId=1234 -Doutcome=REJECTED -DserviceUrl=http://localhost:8080/services/soap
$ mvn clean install -DskipTests -Dgpg.skip -Dmaven.javadoc.skip=true
Open pom.xml and go to the Graph tab to see dependency graph.
cd into the project directory (or, in the case of a multi-module project, cd into the parent/aggregator project) and run the following command:
$ mvn archetype:create-from-project
$ mvn clean
This will generate a bulk of files and folders under the target/generated-sources/archetype directory: From the folder structure you can discard the target directory sub-tree, just mvn clean it.
$ cd target/generated-sources/archetype
$ tree -d

${rootArtifactId} to rename variables, methods, comments, etc that depends on the supplied project name.__rootArtifactId__ to rename files/folders.Netbeans will issue the following mvn command behind the scenes
mvn -DartifactId={artifact id} -DgroupId={group id} -Dversion={version} -Dpackaging=jar -Dfile={path to jar} -DgeneratePom=false install:install- file

Add gpg plugin in a profile as below and then when you need to do a release, add the property to your mvn command:
mvn -DperformRelease=true ...

Maven always uses either one or two settings files. The global settings defined in ${M2_HOME}/conf/settings.xml is always required. The user settings file defined in ${user.home}/.m2/settings.xml is optional. Any settings defined in the user settings take precedence over the corresponding global settings.
# settings.xml
<?xml version="1.0" encoding="UTF-8"?>
<settings xmlns="http://maven.apache.org/SETTINGS/1.1.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.1.0 http://maven.apache.org/xsd/settings-1.1.0.xsd">

First if you do not have one, you need to create a key. To generate a key pair
gpg --gen-key
List all available keys
gpg --list-keys
and send key to pool.sks-keyservers.net server
gpg --keyserver hkp://pool.sks-keyservers.net --send-keys [key]
To check the configuration
mvn clean verify
Possible errors you will get are
Add below line to ~/.bash_profile or ~/.zshrc
GPG_TTY=$(tty)
export GPG_TTY
and reload your .zshrc
source ~/.zshrc
or
. ~/.zshrc
List all available gpg servers
gpg-connect-agent --dirmngr 'keyserver --hosttable'
and select and use an active server in order to send or receive key
gpg --keyserver hkp://keys.openpgp.org --send-keys [key]
gpg --keyserver hkp://keys.openpgp.org --recv-keys [key]
To deploy your application using Maven, create the settings.xml file under the .m2 folder, providing the glassfish profile credentials: they will automatically imported in the pom.xml file.
in your pom.xml file add
<build>
<plugins>
<plugin>
<groupId>org.glassfish.maven.plugin</groupId>
<artifactId>maven-glassfish-plugin</artifactId>
<version>2.1</version>
<configuration>
<glassfishDirectory>${glassfish.home}</glassfishDirectory>
<user>admin</user>
<!--<adminPassword>${glassfish.adminPassword}</adminPassword>-->
<passwordFile>${glassfish.passfile}</passwordFile>
<domain>
<name>domain1</name>

</component>

<debug>true</debug>
<terse>false</terse>
<echo>true</echo>
</configuration>
</plugin>
</plugins>
</build>
and then run
$ mvn clean package glassfish:deploy
in your pom.xml file add
<build>
<plugins>
<plugin>
<groupId>org.wildfly.plugins</groupId>
<artifactId>wildfly-maven-plugin</artifactId>
<version>2.0.0.Final</version>
</plugin>
</plugins>
</build>
and then run
$ mvn clean wildfly:deploy
to backup mysql database for example, add below lines in your pom.xml
<build>
<plugins>
<plugin>
<groupId>org.codehaus.mojo</groupId>

<version>1.2.1</version>

</configuration>
</plugin>

and then run
$ mvn exec:exec -Pproduction
mvn dependency:tree
