maven 学习 十 关于打包

clean package -Dmaven.test.skip=true -P product

这个命令干的活： 清class文件，打包构建，跳过测试，注意最后一个 -P product， 会激活项目下的pom.xml配置的<profiles>标签下id为product。

Maven提供了Profile的概念来决绝不同环境打包的问题：

<profiles>
    <profile>
        <id>kaifa</id>
        <properties>
            <db.url>192.10.2.168</db.url>
            <db.username>dbtest</db.username>
            <db.password>dbtest</db.password>
        </properties>
    </profile>  

    <profile>
        <id>shengchan</id>
        <properties>
            <db.url>192.20.1.11</db.url>
            <db.username>admin</db.username>
            <db.password>comfreesecurity</db.password>
        </properties>
    </profile>
</profiles>  

 常用插件：

• maven-jar-plugin

打成jar时，设定manifest的参数，比如指定运行的Main class，还有依赖的jar包，加入classpath中。

（classpath:classpath是Java运行时环境搜索类和其他资源文件（比如jar\zip等资源）的路径。可以通过JDK工具（比如javac命令、java命令）后面的-

classpath 参数设置classpath）

 <plugin>
                        <artifactId>maven-jar-plugin</artifactId>
                        <configuration>
                            <archive>
                                <manifest>
                                    <mainClass>play.core.server.ProdServerStart</mainClass>  // 主函数
                                    <addClasspath>true</addClasspath>            // 加入到classpath
                                    <classpathPrefix>lib/</classpathPrefix>
                                </manifest>
                                <!-- Add config folder into classpath of MANIFEST -->
                                <manifestEntries>
                                    <Class-Path>conf/</Class-Path>          // 资源文件也加入到classpath
                                </manifestEntries>
                            </archive>
                            <classesDirectory></classesDirectory>
                            <!--<excludes> <exclude>*.conf</exclude> <exclude>*.xml</exclude>
                                </excludes> -->
                        </configuration>
                    </plugin>

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-jar-plugin</artifactId>
    <version>2.4</version>
    <configuration>
        <archive>
            <manifest>
                <addClasspath>true</addClasspath>

            </manifest>
        </archive>
    </configuration>
</plugin>

• maven-dependency-plugin

            用于复制依赖的jar包到指定的文件夹里,

  <plugin>
                        <artifactId>maven-dependency-plugin</artifactId>
                        <executions>

                                    <outputDirectory>${project.build.directory}/lib</outputDirectory>
                                </configuration>
                            </execution>
                        </executions>
                    </plugin>
