Failure to find net.sf.json-lib:json-lib:jar:2.2.2-优快云博客

博客主要讲述项目添加json-lib依赖时，打包执行mvn package报错的问题。提示找不到特定版本jar包，原因是jar名称中多了jdk13、jdk15，需添加classfier。修改配置后可找到对应jar包，还给出了相关参考链接。

Could not resolve dependencies for project com.platform:platform-gateway:jar:1.0: Failure to find net.sf.json-lib:json-lib:jar:2.2.2 in http://maven.aliyun.com/nexus/content/groups/public/ was cached in the local repository, resolution will not be reattempted until the update interval of alimaven has elapsed or updates are forced -> [Help 1]

在项目中添加json-lib依赖时：

<dependency>
    <groupId>net.sf.json-lib</groupId>
    <artifactId>json-lib</artifactId>
    <version>2.4</version>
</dependency>

项目打包时时，执行 mvn package 查看到具体的详细信息：提示： Could not resolve dependencies for project com.platform:platform-gateway:jar:1.0: Failure to find net.sf.json-lib:json-lib:jar:2.2.2 in http://maven.aliyun.com/nexus/content/groups/public/ was cached in the local repository, resolution will not be reattempted until the update interval of alimaven has elapsed or updates are forced -> [Help 1]
的错误

根据提示打开： http://uk.maven.org/maven2/net/sf/json-lib/json-lib/2.4/

看到：

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：

<dependency>
    <groupId>net.sf.json-lib</groupId>
    <artifactId>json-lib</artifactId>
    <version>2.4</version>
    <classifier>JDK15</classifier>
</dependency>

这样配置即可找到json-lib-2.4-jdk15.jar 。
