Các cấu trúc thư mục tiêu chuẩn đi như thế này: các thư mục src là gốc rễ cho tất cả các mã trong dự án, và trong thư mục này, có một thư mục chính (đối với mã sản xuất) và một thư mục kiểm tra. Chỉ có các nội dung thư mục src của (sau khi được thực hiện bất kỳ xử lý / biên soạn) đi vào các tạo tác đóng gói. | 16 CHAPTER 2 GETTING UP AND RUNNING - resources - webapp 1 - jsp - styles - WEB-INF - decorators - test - java - com fdar apress - s2 - resources The standard directory structure goes like this the src directory is the root for all code in the project and within this directory there is a main directory for production code and a test directory. Only the src directory s contents after any processing compiling is performed go into the packaged artifact. Note For more detail on the standard directory structure see the Maven2 documentation at http maven.apache.org guides introduction introduction-to-the-standard-directory-layout. html. These two directories can contain many other directories which are aligned with a plugin or technology. The most common are the java and resource containing property XML and other configuration files directories because Maven2 is a build tool for Java but there are many more. When the AspectJ AspectJ provides a way to weave additional code for crosscutting concerns with logging and transaction management being the commonly used examples into existing compiled code plug-in is included an aspects directory contains the .aj files. The same goes for scripting where a groovy directory contains the Groovy scripts that are to be executed. Groovy is a dynamic scripting language with syntax similar to Java that can be executed on the fly or compiled down to byte code. For a war packaged artifact the main directory includes a webapp directory that contains the additional information for a WAR file that an EAR or JAR does not need. The Maven2 Configuration File As well as the starter program elements the archetype will create a Maven2 pom.xml configuration file that is used to build the project. This file defines the project s dependencies the packaging details and the testing and reporting requirements. The configuration file plays a central role so let s take some time to understand its parts. The first part is the header information CHAPTER 2 .
