maven的命令使用笔记

(1)创建web项目

mvn archetype:create -DgroupId=com.mycompany.webapp -DartifactId=myweb -DarchetypeArtifactId=maven-archetype-webapp

(2)转化成java项目

cmd 进入项目目录下,执行：

mvn eclipse:eclipse

(3)打包而不测试

mvn package -DskipTests=true

mvn clean install -DskipTests=true

(4)打jar包时，复制依赖包：

mvn dependency:copy-dependencies

<plugin>

<groupId>org.apache.maven.plugins</groupId>

<artifactId>maven-dependency-plugin

</artifactId>

<configuration>

<outputDirectory>${basedir}/app/lib

</outputDirectory>

</configuration>

</plugin>

(5)运行测试：

<plugin>

<groupId>org.mortbay.jetty</groupId>

<artifactId>maven-jetty-plugin</artifactId>

</plugin>

mvn jetty:run

(6)安装第三方包：

mvn install:install-file -DgroupId=org.slf4j -DartifactId=slf4j-log4j12 -Dversion=1.5.6 -Dfile=slf4j-log4j12-1.5.6.jar -Dpackaging=jar -DgeneratePom=true

备注：

mvn install:install-file

-DgroupId=<your_group_name>

-DartifactId=<your_artifact_name>

-Dversion=<snapshot>

-Dfile=<path_to_your_jar_file>

-Dpackaging=jar

-DgeneratePom=true

简单解释一下：

archetype 是一个内建插件，他的create任务将建立项目骨架

archetypeArtifactId 项目骨架的类型

可用项目骨架有：

* maven-archetype-archetype

* maven-archetype-j2ee-simple

* maven-archetype-mojo

* maven-archetype-portlet

* maven-archetype-profiles (currently under development)

* maven-archetype-quickstart

* maven-archetype-simple (currently under development)

* maven-archetype-site

* maven-archetype-site-simple, and

* maven-archetype-webapp

(7)解决maven传递依赖中的版本冲突

<plugin>

<groupId>org.apache.maven.plugins</groupId>

<artifactId>

maven-project-info-reports-plugin

</artifactId>

</plugin>

mvn project-info-reports:dependencies 。生成项目依赖的报表，这样你就能够在报表中找出你版本冲突的相关性依赖了。

最后在相应的dependency中加上exclusions来排除相关的传递依赖。

例：

<dependency>

<groupId>jaxen</groupId>

<artifactId>jaxen</artifactId>

<version>1.1.1</version>

<exclusions>

<exclusion>

<groupId>com.ibm.icu</groupId>

<artifactId>icu4j</artifactId>

</exclusion>

</exclusions>

<scope>runtime</scope>

</dependency>

备注pom的简要例子：

<?xml version="1.0" encoding="UTF-8"?>

<project>

<modelVersion>4.0.0</modelVersion>

<groupId>mypro</groupId>

<artifactId>mypro</artifactId>

<version>0.0.1</version>
