maven 相关插件

maven打包配置，到底要打包哪些文件，如何配置？？使用如下插件：

    <build>
        <finalName>weatherAdminSys</finalName>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-war-plugin</artifactId>
                <version>2.1.1</version>
                <configuration>
                    <webXml>webWEB-INFweb.xml</webXml>
                    <webResources>
                        <resource>　　<!-- 重点看 -->
                            <directory>
                                web/
                            </directory>

maven打包带依赖可执行的jar（注意需要指定main所在类）, 执行 mvn clean assembly:assembly命令

执行：java -jar http-client-netty-1.0-SNAPSHOT-jar-with-dependencies.jar

　　　　<plugins>
            <plugin>
                <artifactId>maven-assembly-plugin</artifactId>
                <version>2.2</version>
                <configuration>
                    <archive>
                        <manifest>
                            <mainClass>com.pt.utils.HttpClientUtil</mainClass>
                        </manifest>
                    </archive>
                    <descriptorRefs>
                        <descriptorRef>
                            jar-with-dependencies
                        </descriptorRef>
                    </descriptorRefs>
                </configuration>
