Maven Wrapper:
Normally you instruct users to run the mvn command like the following:
```
$ mvn clean package
```
But now, with a Maven Wrapper setup, you can instruct users to run wrapper scripts:
```
$ ./mvnw clean package
```
or
```
$ ./mvnw.cmd clean package
```
A normal Maven build will be executed with the one important change that if the user doesn’t have the necessary version of Maven specified in .mvn/wrapper/maven-wrapper.properties it will be downloaded for the user first.
(Note: Initial maven-wrapper files were setup as per: maven-wrapper, using: mvn -N io.takari:maven:wrapper. You may wish to use the same command when creating new projects.)
Unit Tests - To run unit tests, using the maven wrapper:
```
$ ./mvnw clean test
```
Install - To install a local snapshot version of this project, for use only by other local projects, run ‘install’:
```
$ ./mvnw clean install
```
Deploy - To deplopy a public/shared snapshot version of this project, for use by other developers, run ‘deploy’. This will deploy the snapshot to the central snapshot repo.

NOTE: This requires the configuration steps described in deploySnapshot.

Snapshot artifacts will be deployed into repository: https://oss.sonatype.org/content/repositories/snapshots.
```
$ ./mvnw clean deploy
```
Other developers must activate the ossrh-snapshot profile to use this repo and see your snapshot:
```
otherproject$ ./mvnw clean test -Possrh-snapshot
```
Release - To release a new, stable version of this project to the public maven central repository, follow the steps described in Release artifacts to OSSRH.
