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，它将解析从引擎的主脚本(Cleartk Stanford工具)导入的内容，然后退出，但出现以下异常:

该引擎是使用Ruta 2.2.0的预发行版创建的，并且管道使用UIMAFIT 2.0.0和使用maven导入的Ruta-core 2.1.0在UIMA 2.5.0中运行。
谢谢你的帮助!
最佳答案
此问题很可能是由于JCas类被覆盖这一事实引起的。 UIMA Ruta提供了一些为种子，推理和其他分析引擎定义的类型的JCas类。其中一种(至少，但最重要)包含用于存储有关批注和更多信息的其他方法:RutaBasic。这些JCas类不能被覆盖。
自述文件中针对应用JCasGenPomFriendly的用户进行了提及:
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>
您能否检查您是否生成了RutaBasic，并且该类是否包含例如setLowMemoryProfile方法。
