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

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

使用预发布的Ruta 2.2.0创建引擎，管道使用UIMAFIT 2.0.0和使用maven导入的Ruta-core 2.1.0在UIMA 2.5.0中运行。

感谢您的帮助！

这个问题很可能是因为JCas类被覆盖了。 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）包含用于存储注释信息的其他方法：RutaBasic。不得覆盖这些JCas类。

README中提到了适用于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>

请问您是否生成了RutaBasic，以及该类是否包含方法setLowMemoryProfile。
