这个JSON处理错误表明了什么？

Question

我正在尝试处理JSON文件，但我不知道为什么会触发此异常。我正在使用示例代码，所以我不确定org.codehaus.jackson是如何工作的。

import java.io.File;

import skf.config.Configuration;
import skf.config.ConfigurationFactory;
import federate.ExcavatorFederate;
import federate.ExcavatorFederateAmbassador;

public class ExcavatorMain {

    private static final File configurationFile = new File(
            "testResources/configuration/conf.json");

    public static void main(String[] args) {
        System.out.println(configurationFile);
        // TODO Auto-generated method stubz
        ExcavatorFederateAmbassador fedamb = new ExcavatorFederateAmbassador();
        ExcavatorFederate fed = new ExcavatorFederate(fedamb);

        ConfigurationFactory factory = null;
        Configuration config = null;

        try {

            factory = new ConfigurationFactory();
            config = factory.importConfiguration(configurationFile);
            fed.configureAndStart(config);

        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

例外情况是：

testResources\configuration\conf.json
Exception in thread "main" java.lang.NoSuchMethodError: org.codehaus.jackson.type.JavaType.<init>(Ljava/lang/Class;I)V
    at org.codehaus.jackson.map.type.TypeBase.<init>(TypeBase.java:34)
    at org.codehaus.jackson.map.type.SimpleType.<init>(SimpleType.java:46)
    at org.codehaus.jackson.map.type.SimpleType.constructUnsafe(SimpleType.java:63)
    at org.codehaus.jackson.map.ObjectMapper.<clinit>(ObjectMapper.java:183)
    at skf.config.ConfigurationFactory.getObjectMapper(ConfigurationFactory.java:72)
    at skf.config.ConfigurationFactory.importConfiguration(ConfigurationFactory.java:53)
    at ExcavatorMain.main(ExcavatorMain.java:25)

我不明白。
