maven打包步骤_maven 构建项目

maven打包 
1：先在pom文件中添加下面配置  jar 
<build>
        <plugins>
            <!-- compiler插件, 设定JDK版本 -->
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <version>2.3.2</version>
                <configuration>
                    <encoding>UTF-8</encoding>
                    <source>1.7</source>
                    <target>1.7</target>
                    <showWarnings>true</showWarnings>
                </configuration>
            </plugin>
            <plugin>
                <artifactId>maven-assembly-plugin</artifactId>
                <configuration>
                    <descriptorRefs>
                        <descriptorRef>jar-with-dependencies</descriptorRef>
                    </descriptorRefs>
                    <archive>
                        <manifest>
                            <mainClass>cn.com.redis.App</mainClass>
                        </manifest>
                    </archive>
                </configuration>
                <executions>
                    <execution>
                        <id>make-assembly</id>
                        <phase>package</phase>
                        <goals>
                            <goal>single</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
        </plugins>
    </build>

　　如果是打war 包修改pom 文件,操作一样.

　　

<build>
        <resources>
            <resource>
                <directory>src/main/resources</directory>
                <filtering>true</filtering>
            </resource>
            <resource>
                <directory>src/main/java</directory>
                <includes>
                    <include>**/*.hbm.xml</include>
                </includes>
            </resource>
            <resource>
                <directory>src/main/resources</directory>
                <includes>
                    <include>**/*.xml</include>
                    <include>**/*.properties</include>
                </includes>
            </resource>
        </resources>
        <!-- 打包文件名，去掉默认打包 版本号 -->
        <finalName>spider_web</finalName>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-eclipse-plugin</artifactId>
                <version>2.6</version>
            </plugin>
             <!-- <plugin>
                <artifactId>maven-compiler-plugin</artifactId>
                <configuration>
                    <source>1.7</source>
                    <target>1.7</target>
                    <encoding>utf-8</encoding>
                </configuration>
            </plugin> -->
            <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>3.1</version>
    <configuration>
        <source>1.7</source> <!-- 源代码使用的开发版本 -->
        <target>1.7</target> <!-- 需要生成的目标class文件的编译版本 -->
        <!-- 一般而言，target与source是保持一致的，但是，有时候为了让程序能在其他版本的jdk中运行(对于低版本目标jdk，源代码中需要没有使用低版本jdk中不支持的语法)，会存在target不同于source的情况 -->

        <encoding>utf-8</encoding> 

    </configuration>
</plugin>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-resources-plugin</artifactId>
                <configuration>
                    <encoding>UTF-8</encoding>
                </configuration>
            </plugin>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-war-plugin</artifactId>
                <version>2.1.1</version>
                <configuration>
                    <warName>spider_web</warName>
                </configuration>
            </plugin>
        </plugins>
    </build>

2：在cmd中窗口中切换到项目根目录，执行下面命令
    mvn clean  package -DskipTests

3：在项目根目录下的target目录下会有两个jar包，使用这个jar包启动：xxxxxxx-jar-with-dependencies.jar

4：执行  java -jar xxxx.jar

二.构建 maven 项目
