UIMA Ruta：无法找到 JCas initialized/Script

Question

我尝试将 UIMA Ruta 脚本 (Main.ruta) 集成到 uimaFIT 管道 (inMain.java) 中，但找不到该脚本。这是我的项目结构：

uima-ruta-maven-test-project/src/main/Main.java
uima-ruta-maven-test-project/script/ruta/Main.ruta
uima-ruta-maven-test-project/descriptor/ruta/MainEngine.xml

这是我创建 AnalysisEngineDescription:

的代码

File file = new File("descriptor/ruta/MainEngine.xml");

AnalysisEngineDescription rutaScript = AnalysisEngineFactory.createEngineDescriptionFromPath(
                    file.getPath(),
                    RutaEngine.PARAM_SCRIPT_PATHS, "script",
                    RutaEngine.PARAM_MAIN_SCRIPT, "Main.ruta");

这是我的控制台输出：

我的控制台输出的最后一行似乎显示了错误。 Main.ruta 在路径 [script;D:\Programming\MA\uima-ruta-maven-test-project] 中搜索，显然不存在，因为它是无效路径。我在想的是 createEngineDescriptionFromPath 方法应该将 "script" 文件夹附加到项目路径。但相反，它在前面。

有人可以帮我解决这个问题吗？

编辑

我在文档中找到 this link，其中解释了参数 mainScript 和 scriptPaths 的用法。路径必须用“.”书写。而不是“/”。

我修改了我的代码如下：

AnalysisEngineDescription rutaScript = AnalysisEngineFactory.createEngineDescriptionFromPath(
                    file.getPath(),
                    RutaEngine.PARAM_SCRIPT_PATHS, "script.ruta",
                    RutaEngine.PARAM_MAIN_SCRIPT, "script.ruta.Main");

但现在我得到这个控制台输出：

Exception in thread "main" org.apache.uima.cas.CASRuntimeException: The JCas cannot be initialized.  The following errors occurred:

Ruta 类型似乎无法初始化。我的 pom.xml.

中有 UIMA Ruta 版本 2.7.0 和 DKPro 2.0.0

Answer 1

似乎 UIMA Ruta 2 与 UIMA v3 和其他依赖它的库（在本例中为 uimaFit、DKPro）不能很好地结合在一起。

我在我的案例中使用了以下版本：DKPro 1.11.0、UIMA 2.10.4、UIMA Ruta 2.7.0 和 uimaFit 2.4.0（另请参阅）。

UIMA Ruta 3 最近发布。我想这个版本会更好地与 UIMA v3 一起工作。
