The creation of MAVEN Series II MAVEN projects and the structure of the MAVEN project

One of the MAVEN series is a brief introduction to MAVEN's basic information, installation and configuration, and everyone has a general understanding of MAVEN, but not enough in MAVEN project development, to learn more about MAVEN, now we introduce the creation of MAVEN projects and the structure of MAVEN projects.

Part I: Creating a MAVEN Project

Maven Project Creation method one: with the command

Start key +r=, OK, detect MAVEN version

Input Mvn-v

Input MVN archetype:generate, execute this command a bit long, to have patience, he will detect setting.xml, do not meet the conditions will be an error. The jar package, the Maven plugin, is also downloaded to the local repository based on the local warehouse address in the setting. So it takes a long time.

After the download is successful, you will be prompted for input, groupid,artifactid,version, and after input, the project will generate the path in the C-drive user directory

2.maven How to create a project two: Create a MAVEN project with Eclipse,idea development tools

One:Eclipse

1. Open Eclipse, right-click new--"Other, if you find Maven project

2. Select Maven Project, display the window to create the MAVEN project, tick, create a simple project

3. Enter the basic information for the MAVEN project as shown in:

4, complete the creation of the MAVEN project, generate the corresponding MAVEN project results, as shown below, some of the structure here is not required by the project, we need to remove:

5, select the project, right-click Properties, go to the property page, select the Maven menu, as shown in:

6, choose Java Version 1.7, and remove the other two, such as:

7, click OK, again back to the project structure, the project structure is relatively clear, in line with the MAVEN project we want to create

8, at this time the results of WebApp is not shown, because at this time we have not configured this project for the Web project, again into the properties configuration, as shown in:

9, click further configuration available ..., as follows:

10. Configure Src/main/webapp, and tick the option to generate Web. XML, as follows:

11. After determining, return to the Maven menu to remove the dynamic Web module check, click OK, as shown below, the WEBAPP directory structure is displayed:

12, at this time also need to configure, Src/main/webapp for the "/" project root directory, as follows:

13, complete the configuration as above, the final completion of the MAVEN WEBAPP project structure as shown:

Part II: Structure of the MAVEN project

A good directory structure makes it easier for developers to understand the project, and also lays a good foundation for future maintenance work. Maven2 provides developers with a default standard catalog template based on the industry's best-known directory structure. The standard directory structure for MAVEN2 is as follows:

Src/main/java	Application/library sources
Src/main/resources	Application/library Resources
Src/main/filters	Resource Filter Files
src/main/assembly	Assembly descriptors
Src/main/config	Configuration files
Src/main/scripts	Application/library scripts
Src/main/webapp	WEB Application sources
Src/test/java	Test sources
Src/test/resources	Test Resources
Src/test/filters	Test Resource Filter Files
Src/site	Site
LICENSE.txt	Project ' s license
NOTICE.txt	Notices and attributions required by libraries, the project depends on
README.txt	Project ' s Readme

You can make pom.xml more concise by using the catalog template. Because the MAVEN2 has predefined related actions based on the default directory, no manual intervention is required. Take the resources directory as an example:

• Src/main/resources, responsible for managing the resources of the project subject. After executing compile with Maven2, all files and subdirectories in this directory are copied to the Target/classes directory, which provides convenience for future packaging.
• Src/test/resources, responsible for managing the resources of the project test. After executing test-compile with Maven2, all files and subdirectories in this directory are copied to the Target/test-classes directory, ready for subsequent tests.

These actions are in Maven1 and need to be done using <preGoal> or <postGoal> in Maven.xml. Today, you can do this automatically without having to specify it in Pom.xml. The use of resources in both SRC and test, which is easy to build and test, has been the experience of previous generations. By using MAVEN2, this experience has been popularized in the development team.
