Maven中解决system的jar依赖，打包复制问题

依赖配置：

    com.alibaba    fastjson

build配置：

父POM中：

    ${project.artifactId}                        ${basedir}/src/main/java                            **/*.xml                **/*.properties                                        ${basedir}/src/main/resources                                                                org.apache.maven.plugins                maven-resources-plugin                2.7                                    UTF-8                                                                    org.apache.maven.plugins                maven-compiler-plugin                3.5.1                                    1.8                    1.8                    UTF-8                                        

子POM中：

                        ${basedir}/src/main/java                            **/*.xml                **/*.properties                                        ${basedir}/src/main/resources                                    org.apache.maven.plugins            maven-dependency-plugin            3.0.2                                                package                                            copy-dependencies                                                                            system                ${project.build.directory}/${project.build.finalName}/WEB-INF/lib                        

子POM中的插件才是解决的关键。
