将maven打包为一个jar（可以体外加入jar）

使用

maven-compiler-plugin插件，

在maven的pom的<build></build>标签中上加入

  <build>
        <plugins>
            <plugin>
                <artifactId>maven-compiler-plugin</artifactId>
                <configuration>
                    <source>1.7</source>
                    <target>1.7</target>
                    <encoding>UTF-</encoding>
                </configuration>
            </plugin>

                            <mainClass>com.sdyy.main.Main</mainClass>   //---------------- 此处要设置main方法的位置
