等等

 

Maven repository dependencies maven 的所有的dependency都可以在上面找到

 

<dependency>
    	<groupId>org.springframework</groupId>
    	<artifactId>spring-core</artifactId>
   	 <version>2.5.6</version>
</dependency> 

 

 

1. mvn command

 

mvn -B archetype:generate -DgroupId=com.demo -Dversion=1.0 -DartifactId=demo -DarchetypeArtifactId=maven-archetype-webapp /*生成web项目的基本框架 */
mvn eclipse:eclipse -Dwtpversion=1.0  /* 转换成eclipse 下的web项目 */

将项目import进eclipse中时，需要给eclipse增加一个classpath variable，步骤：Window->Preferences->Java->Build Path->Classpath Variables，点击 New 按钮添加变量。

Name: M2_REPO

Path: 点击Folder按钮选择你的maven repository目录（如我的为：D:/MavenRepos）

OK，这样项目引用的通过maven获得的jar包就能找到了，当然是在maven repository中。

 

2. setting.xml

修改Maven 2.x 的默认本地仓库存储路径。
Maven 2.X.可以通过修改%MAVEN_HOME%\conf\settings.xml文件来设置本地仓库存储路径，如下：
通过修改Maven全局配置文件来配置Maven的本地仓库目录：

<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
          xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd">

	<localRepository>D:/MavenRepos/</localRepository>

     .........
</settings>

3. pom.xml

SCM 配置

 

   To configure the scm support for maven you need the scm configuration in your pom.xml .

 

<project>
  ...
  <packaging>jar</packaging>
  <version>1.0-SNAPSHOT</version>
  <name>SCM Sample Project</name>
  <url>http://somecompany.com</url>
  <scm>
    <connection>scm:svn:http://somerepository.com/svn_repo/trunk</connection>
    <developerConnection>scm:svn:https://somerepository.com/svn_repo/trunk</developerConnection>
    <url>http://somerepository.com/view.cvs</url>
  </scm>
  ...
</project> 

SCM Implementation: Subversion

SCM Url

scm:svn:svn://[username[:password]@]server_name[:port]/path_to_repository
scm:svn:svn+ssh://[username@]server_name[:port]/path_to_repository
scm:svn:file://[hostname]/path_to_repository
scm:svn:http://[username[:password]@]server_name[:port]/path_to_repository
scm:svn:https://[username[:password]@]server_name[:port]/path_to_repository

 

Examples

scm:svn:file:///svn/root/module
scm:svn:file://localhost/path_to_repository
scm:svn:file://my_server/path_to_repository
scm:svn:http://svn.apache.org/svn/root/module
scm:svn:https://username@svn.apache.org/svn/root/module
scm:svn:https://username:password@svn.apache.org/svn/root/module

 

 

定义自己的结构

新建一个 archetype 项目 ：

mvn archetype:create\
-DgroupId=cn.prof\
-DartifactId=prof-archetype\
-DarchetypeArtifactId=maven-archetype-archetype

       主要的模板文件 ： archetype-resources/pom.xml

       修改其中内容

       修改 META-INF/maven/archetype.xml 中定义了相关的 sources

       安装此项目 ： mvn install

执行下面的命令创建新目录的项目：

mvn archetype:create -DgroupId=com.mergere.mvnbook \
-DartifactId=proficio-example\
-DarchetypeGroupId=com.xxx.mvn\
-DarchetypeArtifactId= prof-archetype \
-DarchetypeVersion=1.0-SNAPSHOT

 

 

Goal	Description
scm:add	Add a file set to the project.
scm:bootstrap	Pull the project source from the configured scm and execute the configured goals.
scm:branch	Branch the project.
scm:changelog	Dump changelog contents to console. It is mainly used to test maven-scm-api's changelog command.
scm:check-local-modification	This mojo will fail the build if there is any local modifications
scm:checkin	Commit changes to the configured scm url.
scm:checkout	Get a fresh copy of the latest source from the configured scm url.
scm:diff	Display the difference of the working copy with the latest copy in the configured scm url.
scm:edit	Edit/lock a set of files.
scm:export	Get a fresh exported copy of the latest source from the configured scm url.
scm:help	Display help information on maven-scm-plugin. Call mvn scm:help -Ddetail=true -Dgoal=<goal-name> to display parameter details.
scm:list	Get the list of project files.
scm:status	Display the modification status of the files in the configured scm url.
scm:tag	Tag the project.
scm:unedit	Unedit/unlock a set of files.
scm:update	Update the local working copy with the latest source from the configured scm url.
scm:update-subprojects	Updates all projects in a multi project build. This is useful for users who have adopted the flat project structure where the aggregator project is a sibling of the sub projects rather than sitting in the parent directory.
scm:validate	Validate scm connection string.
