在项目中添加json-lib依赖时：

项目编译时，执行 mvn compile -X 查看到具体的详细信息：提示： Caused by: org.eclipse.aether.transfer.ArtifactNotFoundException: Failure to find net.sf.json-lib:json-lib:jar:1.5:2.4 in [http://uk.maven.org/maven2/][http_uk.maven.org_maven2] was cached in the local repository, resolution will not be reattempted until the update interval of ui has elapsed or updates are forced  
的错误，

根据提示打开： [http://uk.maven.org/maven2/net/sf/json-lib/json-lib/2.4/][http_uk.maven.org_maven2_net_sf_json-lib_json-lib_2.4]

jar的名称中多了 jdk13、jdk15，所以需要添加classfier。classifier表示在相同版本下针对不同的环境或者jdk使用的jar, 如果配置了这个元素，则会将这个元素名在加在jar包的后面来查找相应的jar，所以上面的json-lib-2,4是找不到jar包的。修改为以下配置：

这样配置即可找到json-lib-2.4-jdk15.jar 。
