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/ 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/
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 。
