• What
is Maven?
• Maven
project lifecycles
• Maven
repositories
• Start a new Maven project in Eclipse
What is Maven?
• Project
management tool which encompasses project object module (pom.xml), project
lifecycle, dependency management, and plugin execution logic
- Maven, the Complete Reference
• Maven
as build tool
§ Dependency
management which includes dependency inheritance
§ Accessing
remote repositories
§ Build
logic reuse with plugins
§ Produces
deployable artifacts
Maven project lifecycles
• Maven
has three default lifecycles: clean, default, site
§ clean
– project cleaning
§ default
– project deployment
§ site
– creates project’s site documentation
• All
lifecycles have numerous phases
§ Each
phase of a
lifecycle is defined
by one or more plugins
and goals
q Building
custom Maven plugins is possible, beyond scope of this training
§ User
defines phase to which Maven runs; Maven executes all phases to that point.
Maven repositories
• Local
repository: ${user.dir}/.m2/repository
§ Configured
in and collocated with ${user.dir}/.m2/settings.xml
§ Can
also be set in Super pom and individual
project pom’s
• Remote
repository: Currently set by default to https://repo.maven.apache.org/maven2
§ Can
be configured in ${user.dir}/.m2/settings.xml
q Will
set repository location for all locally-built Maven projects.
q Most
ideal place to set remote repository.
• To ensure that your newly installed Java
jar is a available as a Maven dependency, build your local index . . .
Start a new Maven project in Eclipse
1. Create
new project: File
> New (> Other…) > Maven Project
2. Choose
a archetype or not
§ Archetypes
are prototypes from which to begin Maven projects
q Possible
to build custom archetypes, beyond the scope of the project
3. Choose
a group Id, artifact Id, version number, description
• File
structure
§ /src/main/java
§ /src/main/resources
§ /src/test/java
§ /src/test/resources
§ Maven
repository
§ Target
folder
§ pom.xml
