UIMA :无法初始化JCas /找不到脚本

Question

我试图在uimaFIT管道中集成uimaFIT脚本(Main.ruta) (在Main.java中)，但是找不到脚本。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

下面是我创建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：

控制台输出的最后一行似乎显示了错误。Main.ruta是在路径[script;D:\Programming\MA\uima-ruta-maven-test-project]中搜索的，这显然不存在，因为它是无效路径。我认为createEngineDescriptionFromPath方法应该将"script"文件夹附加到项目路径。但取而代之的是它的优势。

有人能帮我一下吗？

编辑

我已经找到了这链接，其中解释了参数mainScript和scriptPaths的用法。这些路径必须用“。”而不是"/“。

我修改了代码如下：

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

但是现在我得到了这个控制台输出：

Exception in thread "main" org.apache.uima.cas.CASRuntimeException: The JCas cannot be initialized.  The following errors occurred: 
JCas Class "org.apache.uima.ruta.type.AnyLine", loaded from "jar:file:/C:/Users/user/.m2/repository/org/apache/uima/ruta-typesystem/2.7.0/ruta-typesystem-2.7.0.jar!/org/apache/uima/ruta/type/AnyLine.class", is missing required constructor; likely cause is wrong version (UIMA version 3 or later JCas required).

似乎无法初始化Ruta类型。我的pom.xml中有UIMARutaVersion2.7.0和UIMA2.0.0。

Answer 1

看起来uimaFit 2与UIMA v3和其他依赖它的库(本例中是uimaFit，DKPro )不太协调。

在我的例子中，我使用了以下版本: DKPro 1.11.0、UIMA2.10.4、UIMARuta2.7.0和uimaFit 2.4.0 (也请参阅这个问题)。

UIMA Ruta 3最近发布了。我想这个版本将更好地与UIMA v3一起工作。
