Machine learning 实例提取中的cleartk错误

我尝试运行介绍性的cleartk示例，对文档进行一些修改并使用不同的数据集进行分类。我得到以下错误：

    Exception in thread "main" java.lang.NoSuchMethodError: org.uimafit.util.JCasUtil.selectCovered(Lorg/apache/uima/jcas/JCas;Ljava/lang/Class;

有什么线索吗？我发现这个问题可能有些关联

在我看来，您可能正在使用不兼容的ClearTK和UIMA版本。你的项目设置是什么？您是否使用maven或类似工具来解决依赖关系？如果是这样，您可以发布pom.xml吗？该示例在没有修改的情况下工作了吗？该示例使用uimafit-1.4.0.jar，而我的项目使用uimafit-1.3.1.jar。我可以升级而不需要太多麻烦或破坏项目中的其他东西吗？请让我知道。仅供参考：升级解决了错误。只更换罐子，你不会犯太多错误，因为你可以用旧版本再次更换罐子。如果您使用maven，“升级”（通过更改版本号）也总是可以撤消的，因此在这些情况下，您通常不需要担心破坏东西。
