今天在调试iReport 3.7.5时，忽然报这样一个错：

以调试后才知道maven的pom文件被同事增加一了些其它依赖，而其它依赖又间接地依赖较低版本的json版本(2.1)，而iReport3.7.却要求2.1以上版本的json。问题既然找到，在那个依赖中把较低版本的joson排除即可，如下：
<dependency> <groupId>com.bill99.steel</groupId> <artifactId>steel-old-comp</artifactId> <version>1.0.0-SNAPSHOT</version> [color=red] <exclusions> <exclusion> <groupId>net.sf.json-lib</groupId> <artifactId>json-lib</artifactId> </exclusion> </exclusions>[/color] </dependency>

删除了低版本的json 咋还是报这个错误呢？
