idea pom导入net.sf.json的jar包失败

开始在pom.xml文件中加入依赖如下

<dependency>
    <groupId>net.sf.json-libgroupId>
	<artifactId>json-libartifactId>
	<version>2.2.3version>
dependency>

maven reload project后，项目一直报：

Could not find artifact net.sf.json-lib:json-lib:jar:2.2.3 in nexus-aliyun (https://maven.aliyun.com/nexus/content/groups/public/)
 
Try to run Maven import with -U flag (force update snapshots)

 最后将依赖改成如下，reload 成功了。

<dependency>
	<groupId>net.sf.json-libgroupId>
	<artifactId>json-libartifactId>
	<version>2.2.3version>
    <classifier>jdk15classifier>
dependency>

在此记录一下
