MAVEN项目标准目录结构

 1.标准目录结构:

 

src

  -main
      –bin 脚本库
      –java java源代码文件
      –resources 资源库,会自动复制到classes目录里
      –filters 资源过滤文件
      –assembly 组件的描述配置(如何打包)
      –config 配置文件
      –webapp web应用的目录。WEB-INF、css、js等
  -test
      –java 单元测试java源代码文件
      –resources 测试需要用的资源库
      –filters 测试资源过滤库
  -site Site(一些文档)
target
LICENSE.txt Project’s license
README.txt Project’s readme

工程根目录下就只有src和target两个目录

target是有存放项目构建后的文件和目录,jar包、war包、编译的class文件等。

target里的所有内容都是maven构建的时候生成的

Maven项目的标准目录介绍

 


Maven提倡使用一个共同的标准目录结构,使开发人员能在熟悉了一个Maven工程后,对其他的Maven工程也能清晰了解。这样做也省去了很多设置的麻烦。

以下的文档介绍是Maven希望的目录结构,并且也是目录创建工程是采用的目录结构。Maven推荐大家尽可能的遵守这样的目录结构。

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/webapps

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

README.txt

Project's readme

在顶级目录上是工程的描述文件pom.xml(如果使用Ant则还包括其他属性文件,maven.xmlbuild.xml,另外还包括提供给最终用户的文件,如,README.txt,LICENSE.txt等等。

 

顶级目录还包括两个子目录:src,target。顶级目录下可能出现的其他目录仅仅是CVS或.svn和其他多模块工程的工程目录,最好不要再有其他目录。

 

Target目录是所有工程编译构建的输出目录。

 

Src目录包含所有工程的源码文件,配置文件,资源文件等等。它下面的子目录一般包含main(主要的工程源文件),test(测试文件),site(项目站点文件)。

 

项目构建的生命周期的介绍

 

Maven 2是围绕着构建生命周期概念设计的。这意味着,构建或者发布的过程已经被清晰的定义了。

当我们使用Maven构建工程时,我们只需要了解几个Maven定义好的命令即可,其他的工作则交给POM来完成。

以下给出Maven提供的构建生命周期列表:

validate

validate the project is correct and all necessary information is available.

generate-sources

generate any source code for inclusion in compilation.

process-sources

process the source code, for example to filter any values.

generate-resources

generate resources for inclusion in the package.

process-resources

copy and process the resources into the destination directory, ready for packaging.

compile

compile the source code of the project.

process-classes

post-process the generated files from compilation, for example to do bytecode enhancement on Java classes.

generate-test-sources

generate any test source code for inclusion in compilation.

process-test-sources

process the test source code, for example to filter any values.

generate-test-resources

create resources for testing.

process-test-resources

copy and process the resources into the test destination directory.

test-compile

compile the test source code into the test destination directory

test

run tests using a suitable unit testing framework. These tests should not require the code be packaged or deployed.

package

take the compiled code and package it in its distributable format, such as a JAR.

pre-integration-test

perform actions required before integration tests are executed. This may involve things such as setting up the required environment.

integration-test

process and deploy the package if necessary into an environment where integration tests can be run.

post-integration-test

perform actions required after integration tests have been executed. This may including cleaning up the environment.

verify

run any checks to verify the package is valid and meets quality criteria.

install

install the package into the local repository, for use as a dependency in other projects locally.

deploy

done in an integration or release environment, copies the final package to the remote repository for sharing with other developers and projects.

因此,当我们构建一个项目时,只需要了解自己希望做什么,然后执行以上对应的生命周期即可。

 

例如,我们希望编译我们的工程。在命令行状态下进入到工程的pom.xml文件所在的目录中,使用命令:mvn compile;希望构建打包我们的工程,使用mvn package即可。

 

当然了,maven的构建生命周期也是可以扩展和自定义的,这里就先不做介绍了。
