Failure to find net.sf.json-lib:json-lib:jar:2.2.2

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]

在項目中添加json-lib依賴時：

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

項目打包時時，執行 mvn package 查看到具體的詳細信息：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]
的錯誤

根據提示打開： http://uk.maven.org/maven2/net/sf/json-lib/json-lib/2.4/

看到：

jar的名稱中多了 jdk1三、jdk15，因此須要添加classfier。classifier表示在相同版本下針對不一樣的環境或者jdk使用的jar, 若是配置了這個元素，則會將這個元素名在加在jar包的後面來查找相應的jar，因此上面的json-lib-2,4是找不到jar包的。修改成如下配置：

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

這樣配置便可找到json-lib-2.4-jdk15.jar 。
