I am trying to run an existing UIMA Ruta analysis engine from a UIMAFIT simple pipeline using the following code:

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

Upon running it, it resolves imports from the engine's main script (the Cleartk Stanford tools) and then quits with the following exception:

Exception in thread "main" java.lang.NoSuchMethodError: org.apache.uima.ruta.type.RutaBasic.setLowMemoryProfile(Z)V

The engine was created using a pre-release of Ruta 2.2.0 and the pipeline runs in UIMA 2.5.0 using UIMAFIT 2.0.0 and Ruta-core 2.1.0 imported using maven.

Thanks for any help!

这个问题很可能是由 JCas 类被覆盖的事实引起的。UIMA Ruta 提供了一些为播种、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）包含用于存储有关注释等信息的其他方法：RutaBasic。这些 JCas 类不得被覆盖。

README 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 以及该类是否包含例如方法 setLowMemoryProfile。
