Here I am showing you how to creat your own MAVEN Tree/project:

In this, the files/maven folder structure will be downloaded from maven central to your local machine, so internet is required.

The content is given on the Maven website : 

https://maven.apache.org/guides/introduction/introduction-to-archetypes.html

There are various Archetypes are given:

Let me show you on my local machine how do I install and created my folder:

First, navigate to cmd to your specified folder where you want those three to be developed: 

 and provide command: 

C:\Users\Desktop\ankMavenPrac>mvn archetype:generate

where :    " mvn " is batchfile ,    "archetype" is plugin    &    "generate" is goal

Maven Coordinates  = groupId + artifactId + version

Once all files downloaded from Central to local, the system will ask you for Maven Coordinates :

To check the maven project tree:

 go to   ->   cd sample1 

C:\Users\Desktop\ankMavenPrac\sample1>tree

Maven Goals: 

There are basically three stages in the lifecycle in Maven that is :

1. Clean ,
2. Default and 
3. Site 

1. Clean: The clean phase in the maven lifecycle has three phases pre-clean, clean & post-clean.

2. Default: This phase comprises 23 phases which are validate, initialize, generate-sources, process-sources, generate-resources, process-resources, compile, process-classes, generate-test-sources, process-test-sources, generate-test-resources, process-test-resources, test compile, process-test-classes, test, prepare-package, package, pre-integration-test, integration-test, pots-integration-test, verify, install,  and deploy.

3. Site: Ths is is the final stage in the maven lifecycle having 4 phases: pre-site, site, post-site & site-deploy.

So if the user provides, any phase like from down in the flowchart: COMPILE so that all phases would flow since from pre-clean to compile.

Similarly, if we provide site,  so it would flow all phases since from pre-clean to site.

No need to provide each and every phase during run.
