Build a Maven project in eclipse 1 environment installation and distribution

MAVEN is a software project management tool that is based on a Project object model (POM) that can manage the construction, reporting, and documentation of a project through a short description of the information. Maven primarily serves the Java platform-based project building, dependency management, and project information management, whether it's a small open source class library project or a large enterprise application.

To put Maven in the installation process and configure Maven in Eclipse, see my blog in Open source China:

1.1 Building a Java project with Maven

1 "Using Maven in DOS to build Java projects look at my view of the Open source China Blog:

2 "Building projects with Maven under Eclipse

1) Create a simple MAVEN project

Click the Eclipse menu bar File->new->ohter->maven to get the dialog box as shown:

Select Maven Project and click Next to the next dialog box

Continue clicking next to get the following dialog box

Select Maven-archetype-quickstart, click Next to get the following:

Fill in the GroupID, artfactid,version and other information as shown, click Finish.

Simply explain the Group ID, Artifact ID, Version, and package:

Groupid:group translation into Chinese is the group, the group's consciousness, GroupId is such a group or group ID, take Apache to say good, apache everyone is not unfamiliar it,

Apache Online has a lot of projects, each project will certainly be able to find org.apache.xxxx, and Org.apache is here to say groupId

Artifactid: or Apache, Apache online has a lot of projects, and each project name is here Artifactid, in other words, Artifactid is your project name

Version: There is no good explanation for this, it's the project version.

Package: This also has nothing to say, is Groupid.artifactid, the creation of the time will automatically help you to complete, if not automatically help you fill up your own manually knocked Up

As a result, we have successfully created a simple MAVEN project with a project structure

2) Creating a MAVEN Web project

Action is similar to creating a simple Maven project, click the Eclipse menu File->new->other->maven->maven project

In the Select Maven-archetype interface, do the following:

Click Next, fill in the appropriate groupid,artifactid,version and other information, click Finish

The resulting MAVEN Web project structure is shown in

Describe the directory structure

Src/main/resources: Used to store resource files (default will help you create this resource folder)

Src/main/java: Used to store Java source files (you need to create them manually)

Src/main/test: Used to store the test code (need to create their own manually, also some people used to name: Src/test) @

Target: A place to store Maven compiled bytecode

Maven Dependencies: A maven-managed jar file in the inside

Run a MAVEN managed project,

.  3) run the MAVEN command

Right-click the project and click Run as, such as:

You can see a lot of existing MAVEN commands, click to run, and see the running information in the console

If the MAVEN command you want to run is not found here, click Maven Build to create a new command, as shown in the following:

If you fill in the Maven command, click Run

The new Maven command can be found in the following ways and run again:

It is common to run Maven install. If a Java project generates a jar package, if a Java Web project generates a war package,

Then the Java Web can be run with Tomcat.

1.2 Maven's compilation process

In fact, we generally use the MVN install command to package the project directly at a time, do not have to perform the rest of the MVN compile, MVN packages and other commands, because the implementation of the MVN install command, will be executed in these commands, now we can look at MVN What Intall has done:

1. Initialize initializing some environments

2. Process-sources processes the Project master resource file, which is typically a variable substitution of the contents of the/src/main/resources directory, and is copied into the project's main classpath directory.

3. Compile compile the main source of the project, is generally Src/main/java

4. Process-test-sources working with Project test resource files

5. Test-compile test code for compiling a project

6. The package packages the compiled code

7. Install installs the installation package to the MAVEN local repository for use by other local MAVEN projects
