Maven中解决system的jar依赖，打包复制问题

依赖管理配置：

<dependency>
    <groupId>com.alibaba</groupId>
    <artifactId>fastjson</artifactId>
    <version>1.2.29</version>
    <scope>system</scope>
    <!--<systemPath>${project.basedir}/lib/fastjson-1.2.29-SNAPSHOT.jar</systemPath>-->
    <systemPath>E:/projectsx/lecing/lecing5/code/back/lib/fastjson-1.2.29-SNAPSHOT.jar</systemPath>
</dependency>

依赖配置：

<dependency>
    <groupId>com.alibaba</groupId>
    <artifactId>fastjson</artifactId>
</dependency>

build配置：

父POM中：

<build>
    <finalName>${project.artifactId}</finalName>
    <resources>
        <resource>
            <directory>${basedir}/src/main/java</directory>
            <includes>
                <include>**/*.xml</include>
                <include>**/*.properties</include>
            </includes>
        </resource>
        <resource>
            <directory>${basedir}/src/main/resources</directory>
        </resource>
    </resources>
    <pluginManagement>
        <plugins>
            <!-- 资源文件拷贝插件 -->
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-resources-plugin</artifactId>
                <version>2.7</version>
                <configuration>
                    <encoding>UTF-8</encoding>
                </configuration>
            </plugin>
            <!-- java编译插件 -->
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <version>3.5.1</version>
                <configuration>
                    <source>1.8</source>
                    <target>1.8</target>
                    <encoding>UTF-8</encoding>
                </configuration>
            </plugin>
        </plugins>
    </pluginManagement>
</build>

子POM中：

<build>
    <resources>
        <resource>
            <directory>${basedir}/src/main/java</directory>
            <includes>
                <include>**/*.xml</include>
                <include>**/*.properties</include>
            </includes>
        </resource>
        <resource>
            <directory>${basedir}/src/main/resources</directory>
        </resource>
    </resources>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-dependency-plugin</artifactId>
            <version>3.0.2</version>
            <executions>
                <execution>
                    <phase>package</phase>
                    <goals>
                        <goal>copy-dependencies</goal>
                    </goals>
                </execution>
            </executions>
            <configuration>
                <includeScope>system</includeScope>
                <outputDirectory>${project.build.directory}/${project.build.finalName}/WEB-INF/lib</outputDirectory>
            </configuration>
        </plugin>
    </plugins>
</build>

子POM中的插件才是解决的关键。
