archetype architects

When you create a MAVEN project template by mvn archetype:generate This interaction, you often get stuck in the generating project in Interactive mode prompt (Figure 1).Read the online post (the article at the bottom of the note), found to get archetype-catalog.xml caused by (browser access to Http://repo1.maven.org/maven2/archetype-catalog.xml, need to wait a long time to get to).In fact, the download will

needs to download the required plugins from the Web. The following steps can be problematic if the initial exposure to Maven is possible, but first, the focus is on explaining some concepts later. Next execute the command$mvn archetype:generate -DgroupId=com.mycompany.helloworld -DartifactId=helloworld -Dpackage=com.mycompany.helloworld -Dversion=1.0-SNAPSHOTThe Archetype:generate goal will list a series of archetype to make you choose.

. decompress the apache-maven-2.0.10-bin.zip to the directory you want, such as/usr/local/Apache-Maven, then the decompressed directory is/usr/local/Apache-Maven/apache-maven-2.0.102. export m2_home =/usr/local/Apache-Maven/apache-maven-2.0.103.export m2 = $ m2_home/bin4. (optional) Optional environment variable maven_opts, for example if you want to change Java heap (HEAP) you can set the value to-xms256m-xmx512m. This option is very useful in some cases, when you use MVN site to generate a sit

plug-ins, there are a lot of plug-ins available for selection, such as plug-ins combined with eclipse and plug-ins related to test, later we will introduce Maven in detail in the project. Figure 1 2. Project Management Maven officially defines Maven as a project management tool. Let's take a look at what kind of support Maven can provide to our project.2.1 Project StandardizationAn important feature of Maven is to define the standard template of the project. The official saying is best practice

1. Common commands 1) create a project MVN archetype: generate-dgroupid = com. mycompany. app-dartifactid = My-app-darchetypeartifactid = Maven-Archetype-Quickstart-dinteractivemode = false MVN archetype: Generate fixed format -Dgroupid: Organization ID (package name) -Dartifactid project name -DarchetypeartifactidSpecify Archetypeid, Maven-

information, see "next". That is, create an empty maven project without using any archetype. Next, enter the maven coordinate 3 elements (GroupId, ArtifactId, Version) and continue Next Next, enter the Module name. I personally think it should be improved here. The best Module name is the ArtifactId you just entered by default, which can reduce user input and click Finish. You can see that the folder structure is displayed in the Project directory

complete, run the following command on the command line: $ MVN-VApache Maven 3.0.3 (r00005438; 01:31:09 + 0800)Maven home:/home/Limin/bin/maven3Java version: 1.6.0 _ 24, vendor: Sun Microsystems Inc.Java home:/home/Limin/bin/jdk1.6.0 _ 24/JREDefault locale: en_us, platform encoding: UTF-8OS name: "Linux", version: "2.6.35-28-generic-pae", arch: "i386", family: "Unix"If you see the above output, it indicates that the installation is successful.Next we will use Maven to build the most famous "He

Common Maven commands: 1. Create a normal Java project for Maven: MVN archetype: Create -Dgroupid = packagename -Dartifactid = projectname 2. Create a Maven web project: MVN archetype: Create -Dgroupid = packagename -Dartifactid = webappname -Darchetypeartifactid = Maven-Archetype-webapp 3. CompileSource code: MVN compile 4. Compile and TestCode: MVN t

line to build our Hello World project~ $MVN archetype:generate-dgroupid=com.mycompany.helloworld-dartifactid=helloworld-dpackage= Com.mycompany.helloworld-dversion=1.0-snapshotThe Archetype:generate goal will list a series of archetype to make you choose. Archetype can be understood as a model of the project. Maven provides us with a variety of project models, from simple Swing to complex Web applications.

The tools you need: Maven 3.3.3 Eclipse 4.2 JDK 8 Note: Make sure that Maven is properly installed and configured (in the Windows,*nix,mac OSX system), and then start this tutorial to avoid the MVN command not finding errors. 1. Create a project from the Maven templateIn the terminal (* Unix or Mac) or command prompt (Windows), browse to the folder where you want to create the Java project. Type the following command:MVN archetype
