maven

maven

编译源代码：mvn compile （或者：mvn compiler:compile）

编译测试代码：mvn test-compile

运行测试：mvn test

产生site：mvn site

打包：mvn package

在本地Repository中安装jar：mvn install

清除产生的项目：mvn clean

生成eclipse项目：mvn eclipse:eclipse

生成idea项目：mvn idea:idea

组合使用goal命令，如只打包不测试：mvn -Dtest package

编译测试的内容：mvn test-compile

只打jar包: mvn jar:jar

只测试而不编译，也不测试编译：mvn test -skipping compile -skipping test-compile (这里要特别注意 -skipping 的灵活运用，当然也可以用于其他组合命令)

清除eclipse的一些系统设置:mvn eclipse:clean

生成eclipse工程

打开命令提示符，进入指定的项目目录D：/testapp ,

执行以下命令：

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

其中 my-webapp是项目名，这样就生成了一个web项目，

然后 cd my-webapp进入此项目主目录，执行：mvn eclipse:eclipse

后项目my-webapp就变成了eclipse工程项目了。

用eclipse打开后，如果发现报如下错误：Unbound classpath variable: 'M2_REPO/junit/junit/3.8.1/junit-3.8.1.jar' in project my-webapp ，这是因为在Eclipse 没有配置 M2_REPO 变量，配置步骤：window >> preferences >> Java >> Build Path >> Classpath Variables
新建一个 M2_REPO 的变量，变量值指向你系统的Maven2的数据仓库位置。

mvn archetype:create -DgroupId=com.hs.common
-DartifactId=common
-DarchetypeArtifactId=maven-archetype-webapp-

mvn install:install-file -DgroupId=com.danga -DartifactId=memcached -Dversion=2.0.1 -Dfile=java_memcached-release_2.0.1.jar -Dpackaging=jar \-DgeneratePom=true

maven添加非官方jar包到本地库 (安装到maven库：mvn install -Dmaven.test.skip=true (忽略测试代码))

mvn install:install-file
-DgroupId=<your_group_name>
-DartifactId=<your_artifact_name>
-Dversion=<snapshot>
-Dfile=<path_to_your_jar_file>
-Dpackaging=jar
-DgeneratePom=true

安装客户自己的jar包

mvn install:install-file
-DgroupId=com.danga
-DartifactId=memcached
-Dversion=2.0.1
-Dfile=java_memcached-release_2.0.1.jar (或者/d:/java_memcached-release_2.0.1.jar)
-Dpackaging=jar -DgeneratePom=true

1.maven-helloword:
mvn archetype:create -DgroupId=com.demo -DartifactId=com.demo
-DpackageName=com.demo
将在cmd目录中所在的盘符位置创建一个文件夹com.demo的文件夹
创建一个包名是com.demo的java类.类名是系统默认的App;
2.项目打包:
mvn jar:jar 把项目打成jar
mvn jar:test jar 把测试项目打成jar包
运行jar
java -cp simple-1.0-SNAPSHOT.jar com.demo.App
3.运行单元测试
mvn test
3.1忽略测试失败的情况
<project>
  <build>
   <plugins>
   <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <configuration>
     <testFailureIgnore>true</testFailureIgnore>
    </configuration>
   </plugin>
   </plugins>
  </build>
</project>

mvn test -Dmaven.test.failure.ignore=true;
3.2跳过单元测试
3.1忽略测试失败的情况
<project>
  <build>
   <plugins>
   <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <configuration>
     <skip>true</skip>
    </configuration>
   </plugin>
   </plugins>
  </build>
</project>
mvn install -Dmaven.test.skip=true;
4.maven 创建web项目
mvn archetype:create -DgroupId=com.mycompany.app -DartifactId=my-webapp -DarchetypeArtifactId=maven-archetype-webapp
创建的web项目名:my-webapp
web项目初始化后的pom
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>com.mycompany.app</groupId>
<artifactId>my-webapp</artifactId>
<packaging>war</packaging>
<version>1.0-SNAPSHOT</version>
<name>my-webapp Maven Webapp</name>
<url>http://maven.apache.org</url>
<dependencies>
    <dependency>
      <groupId>junit</groupId>
      <artifactId>junit</artifactId>

      <scope>test</scope>
    </dependency>
</dependencies>
<build>
    <finalName>my-webapp</finalName>
</build>
</project>
其中 finalName 表示的是生成的war包的名字
5.maven jetty插件配置
<project>
<build>
<plugins>
            <plugin>
                <groupId>org.mortbay.jetty</groupId>
                <artifactId>maven-jetty-plugin</artifactId>
                <version>6.1.7</version>
                <configuration>
                    <scanIntervalSeconds>5</scanIntervalSeconds>
                    <connectors>
                        <connector implementation="org.mortbay.jetty.nio.SelectChannelConnector">
                            <port>8080</port>
                            <maxIdleTime>60000</maxIdleTime>
                        </connector>
                    </connectors>
                </configuration>
            </plugin>
</plugins>
</build>
</project>
启动jetty:
mvn clean -Dmaven.test.skip=true jetty:run
6.maven 多模块开发
