从UIMAFIT SimplePipeline运行UIMAFIT脚本时的NoSuchMethodError

Question

我试图使用以下代码从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

在运行它时，它解析从引擎的主脚本()导入，然后退出，但有以下例外：

引擎是使用预发布的Ruta2.2.0创建的，管道运行在UIMA2.5.0中，使用UIMAFIT 2.0.0和使用maven导入的Ruta 2.1.0。

谢谢你的帮助！

这个问题很可能是由JCas类被覆盖这一事实引起的。UIMA提供了一些为种子、推理和附加分析引擎定义的类型的JCas类。其中之一(至少，但最重要的是)包含了用于存储有关注释和更多信息的其他方法: RutaBasic。不能覆盖这些JCas类。

自述文件中提到了应用JCasGenPomFriendly的用户：

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> 

请检查您是否生成了RutaBasic，以及类是否包含setLowMemoryProfile方法。
