Goals:

archetype:createDeprecated.Please use the generate mojo instead.
archetype:create-from-projectCreates an archetype from the current project.
archetype:generateGenerates a new project from an archetype.
archetype:helpDisplay help information on maven-archetype-plugin. Call
mvn archetype:help -Ddetail=true -Dgoal=
to display parameter details.

Usage:

Maven Eclipse Plugin

Maven Eclipse Plugin 用来创建Eclipse的项目文件（(*.classpath, *.wtpmodules and the .settings）。
参考：http://maven.apache.org/plugins/maven-eclipse-plugin/index.html

Goals：

eclipse:configure-workspaceis used to add the classpath variable M2_REPO to Eclipse which points to your local repository and optional to configure other workspace features.
eclipse:eclipsegenerates the Eclipse configuration files.
eclipse:cleanis used to delete the files used by the Eclipse IDE.
eclipse:myeclipseGenerates the MyEclipse configuration files.
eclipse:myeclipse-cleanDeletes the config files used by MyEclipse.
eclipse:help：Display help information on maven-eclipse-plugin.

Usage：

在Elcipse使用本地的maven资源库，通过如下命令将M2_REPO变量加入到eclipse

mvn eclipse:configure-workspace \
-Declipse.workspace=testworkspace \
-Declipse.workspaceCodeStylesURL=http://svn.apache.org/repos/asf/maven/plugins/trunk/maven-eclipse-plugin/src/optional/eclipse-config/maven-styles.xml
（或者mvn -Declipse.workspace= eclipse:add-maven-repo）
在.metadata\.plugins\org.eclipse.core.runtime\.settings\org.eclipse.jdt.core.prefs中会创建：
#Fri Nov 12 13:45:10 CST 2010
org.eclipse.jdt.core.classpathVariable.M2_REPO=C\:
Documents and Settings\\Administrator\\.m2
repository
并且将workspaceCodeStylesURL指定的code styles format文件存放在org.eclipse.jdt.ui.prefs中。

创建eclipse项目配置文件，如：.projectand .classpath files 等

2.1 Load Coding Styles into Workspace
mvn eclipse:eclipse -Declipse.projectDir=. \
-Declipse.workspaceCodeStyleURL=http://svn.apache.org/repos/asf/maven/plugins/trunk/maven-eclipse-plugin/src/optional/eclipse-config/maven-styles.xml
或者在pom.xml中配置

org.apache.maven.plugins
maven-eclipse-plugin
2.8

${basedir}
http://svn.apache.org/repos/asf/maven/plugins/trunk/maven-eclipse-plugin/src/optional/eclipse-config/maven-styles.xml


2.2 Configure Checkstyle

2.3 Multpile Module Project
2.3.1 垂直的工程结构

1. 在eclipse中设置MO_REPO classpath变量
2. 打开window命令窗口，进入workspace目录
3. 通过命令创建一个maven父工程

mvn archetype:create -DgroupId=cn.bidlink -DartifactId=myproject

1. 删除src目录，修改pom.xml文件中的packaing为pom：pom
2. 在父工程下创建多个maven子工程

cd myproject
mvn archetype:create -DgroupId=cn.bidlink -DartifactId=myproject-site
mvn archetype:create -DgroupId=cn.bidlink.core -DartifactId=myproject-core
mvn archetype:create
-DarchetypeGroupId=org.apache.maven.archetypes -DarchetypeArtifactId=maven-archetype-webapp
-DgroupId=cn.bidlink -DartifactId=myproject-webapp

1. 父工程自动将子工程添加在自己的pom.xml中：

myproject-site
myproject-core
myproject-webapp

1. 子工程的pom中自动继承父工程：

cn.bidlink
myproject
1.0-SNAPSHOT

1. 子工程之间的依赖，将core子工程添加到myproject-webapp中

cn.bidlink.core
myproject-core
1.0-SNAPSHOT

1. 创建eclipse项目工程

mvn install
mvn eclipse:eclipse

1. 在eclispe通过import导入myproject，将会在eclipse创建myproject-webapp,module,site等三个工程，且module中自动会应用core工程。

2.3.2扁平的工程结构

1. 在myproject中创建一个新目录parent,将myproject下的pom.xml文件移到该目录下
2. 修改pom.xml文件的子工程

../myproject-site
../myproject-core ../myproject-webapp

1. 修改子工程pom.xml中的parent引用

myproject
cn.bidlink
1.0-SNAPSHOT
../parent/pom.xml

注意：扁平的工程结构有很多maven plguin 如：release插件不支持。

Maven AntRun Plugin

Antrun plugin提供了执行ant中的task的功能，可以将ant的task放在pom中。

Goals:

antrun:helpDisplay help information on maven-antrun-plugin. Call
mvn antrun:help -Ddetail=true -Dgoal=
to display parameter details.
antrun:runMaven AntRun Mojo. This plugin provides the capability of calling Ant tasks from a POM by running the nested ant tasks inside the parameter. It is encouraged to move the actual tasks to a separate build.xml file and call that file with an task.

Usage:

1.在pom中使用ant的task

org.apache.maven.plugins
maven-antrun-plugin
1.6


compile
compile













run



推荐将ant的task单独放在一个build.xml文件中，通过如下方式使用：

org.apache.maven.plugins
maven-antrun-plugin
1.6


compile
compile












run




其中build.xml定义如下：

使用自定义的task

"log4j.log4j.jar.path" value="${log4j:log4j:jar}" />
"net/sf/antcontrib/antcontrib.properties">

"for" classname="net.sf.antcontrib.logic.For">

"${log4jproperties}" delimiter="," param="propertykey">

"propertyvalue" from="@{propertykey}" override="true"/>
"src/main/resources/log4j.properties">
"@{propertykey}" value="${propertyvalue}"/>

@{propertykey}=${propertyvalue}

Maven Dependency Plugin

Dependency Plugin提供了对项目依赖的artifacts的操作管理。

Goals：

1. dependency:copytakes a list of artifacts defined in the plugin configuration section and copies them to a specified location, renaming them or stripping the version if desired. This goal can resolve the artifacts from remote repositories if they don't exist in local.
2. dependency:copy-dependenciestakes the list of project direct dependencies and optionally transitive dependencies and copies them to a specified location, stripping the version if desired. This goal can also be run from the command line.
3. dependency:unpacklike copy but unpacks.
4. dependency:unpack-dependencieslike copy-dependencies but unpacks.
5. dependency:resolvetells Maven to resolve all dependencies and displays the version.
6. dependency:listis an alias for dependency:resolve
7. dependency:sourcestells Maven to resolve all dependencies and their source attachments, and displays the version.
8. dependency:resolve-pluginsTells Maven to resolve plugins and their dependencies.
9. dependency:listalias for resolve that lists the dependencies for this project.
10. dependency:go-offlinetells Maven to resolve everything this project is dependent on (dependencies, plugins, reports) in preparation for going offline.
11. dependency:purge-local-repositorytells Maven to clear all dependency-artifact files out of the local repository, and optionally re-resolve them.
12. dependency:build-classpathtells Maven to output the path of the dependencies from the local repository in a classpath format to be used in java -cp. The classpath file may also be attached and installed/deployed along with the main artifact.
13. dependency:analyzeanalyzes the dependencies of this project and determines which are: used and declared; used and undeclared; unused and declared.
14. dependency:analyze-onlyis the same as analyze, but is meant to be bound in a pom. It does not fork the build and execute test-compile.
15. dependency:analyze-dep-mgtanalyzes your projects dependencies and lists mismatches between resolved dependencies and those listed in your dependencyManagement section.
16. dependency:treedisplays the dependency tree for this project.

Usage:

使用依赖关系的tree结构解决依赖冲突

mvn dependency:tree -Dverbose -Dincludes=commons-collections
将看到
[INFO] [dependency:tree]
[INFO] org.apache.maven.plugins:maven-dependency-plugin:maven-plugin:2.0-alpha-5-SNAPSHOT
[INFO] +- org.apache.maven.reporting:maven-reporting-impl:jar:2.0.4:compile

可以很清楚看到相关冲突信息

Maven Assembly Plugin

Assembly 插件提供了手动对某些文件和依赖打成各种包格式的功能。

Goals:

assembly:helpDisplay help information on maven-assembly-plugin. Call
mvn assembly:help -Ddetail=true -Dgoal=
assembly:singleAssemble an application bundle or distribution from an assembly descriptor. This goal is suitable either for binding to the lifecycle or calling directly from the command line (provided all required files are available before the build starts, or are produced by another goal specified before this one on the command line).

Usage:

打web service客户端包

1. 创建assembly配置文件，如：src/main/assembly/space-ws-jar.xml

<assemblyxmlns="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.2"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.2http://maven.apache.org/xsd/assembly-1.1.2.xsd">

分析eoss-base的dependency,打开debug信息，并且输出到log.txt文件中
E:\workspaces\eossmvn\eoss-core>mvn dependency:tree -Dverbose -Dincludes=eoss-ba
se -X -l log.txt

例2：

使用线下编译方式，不从远程资源库下载包
mvn -o compile
