uima - 从 UIMAFIT SimplePipeline 运行 UIMA Ruta 脚本时出现 NoSuchMethodError

Question

我正在尝试使用以下代码从 UIMAFIT 简单管道运行现有的 UIMA Ruta 分析引擎:

File specFile = new File("MyEngine.xml");
XMLInputSource in = new XMLInputSource(specFile);
ResourceSpecifier specifier = UIMAFramework.getXMLParser().parseResourceSpecifier(in);
AnalysisEngineDescription aed = (AnalysisEngineDescription) specifier;
builder.add(aed); // Builder is an aggregateBuilder

运行它时，它会解析来自引擎主脚本(Cleartk Stanford 工具)的导入，然后退出并出现以下异常:

该引擎是使用 Ruta 2.2.0 的预发布版本创建的，管道在使用 UIMAFIT 2.0.0 的 UIMA 2.5.0 和使用 Maven 导入的 Ruta-core 2.1.0 中运行。

感谢您的帮助!

这个问题很可能是JCas类被覆盖造成的。 UIMA Ruta 提供了一些为播种、推理和其他分析引擎定义的类型的 JCas 类。其中之一(至少，但最重要)包含用于存储有关注释等信息的附加方法:RutaBasic。不得覆盖这些 JCas 类。

README 中为应用 JCasGenPomFriendly 的用户提到:

If you use the uimaFIT JCasGenPomFriendly in Maven and want to use UIMA Ruta 
as a standalone annotator you have to exclude the generated UIMA Ruta basic 
type files from the build, e.g., by adding:

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-compiler-plugin</artifactId>
  <version>3.0</version>
  <configuration>
     <excludes>
         <exclude>org/apache/uima/ruta/type/*.java</exclude>
     </excludes>
  </configuration>
</plugin> 

您能否检查一下您是否生成了 RutaBasic，以及该类是否包含例如 setLowMemoryProfile 方法。
