GATE 8.0编译器问题

Question

我一直在尝试用Groovy (使用Eclipse)构建一个简单的应用程序来调用GATE，并且偶然发现了令人困惑的编译器错误--几年前我在GATE用户身上看到过类似的问题，但是没有一个解决方案能帮我修复这个错误。

代码：

import gate.*
import gate.creole.*
import gate.creole.SerialAnalyserController
import gate.util.persistence.PersistenceManager

class AnnieExtraction {

    static main(args) {
        println "--Initializing GATE--"
        Gate.init()
        Gate.getCreoleRegister().registerDirectories(new File("C:/apps/GATE_Developer_8.0/plugins/ANNIE").toURI().toURL())
        println "--GATE initialized--"

        SerialAnalyserController pipeline = (SerialAnalyserController) Factory.createResource("gate.creole.SerialAnalyserController")
        println "--Initializing PR--"
        ProcessingResource token = (ProcessingResource) Factory.createResource("gate.creole.tokeniser.DefaultTokeniser", Factory.newFeatureMap())


    }

}

并返回错误：

Error: The type postprocessCannotActionClass4 must implement the inherited abstract method RhsAction.doit(Document, Map, AnnotationSet, AnnotationSet, Ontology) at line 10 in japeactionclasses.postprocessCannotActionClass4
Error: The type Map is not generic; it cannot be parameterized with arguments <String, AnnotationSet> at line 18 in japeactionclasses.postprocessCannotActionClass4
Error: Syntax error, parameterized types are only available if source level is 5.0 at line 18 in japeactionclasses.postprocessCannotActionClass4
Error: Type mismatch: cannot convert from Object to Annotation at line 24 in japeactionclasses.postprocessCannotActionClass4
Error: The operator + is undefined for the argument type(s) Long, long at line 31 in japeactionclasses.postprocessCannotActionClass4

The offending input was:

20                     gate.creole.ontology.Ontology ontology) throws gate.jape.JapeException {
21      gate.AnnotationSet cannotAnnots = bindings.get("cannot");
22      if(cannotAnnots != null && cannotAnnots.size() != 0) {
23 
24    Annotation cannot = cannotAnnots.iterator().next();
25    String cannotStr = cannot.getFeatures().get("string").toString();
26    String canStr = cannotStr.substring(0,3);
27    String notStr = cannotStr.substring(3,6);
28 
29    Long start = cannot.getStartNode().getOffset();
30    Long end   = cannot.getEndNode().getOffset();
31    Long middle = start + 3L;
32 
33    /* Copy orth, &c., from the original Token;
34     * overwrite the others appropriately.  */
35    FeatureMap canFM = Factory.newFeatureMap();
36    FeatureMap notFM = Factory.newFeatureMap();
37    canFM.putAll(cannot.getFeatures());
38    notFM.putAll(cannot.getFeatures());
39 
40    canFM.put("string", canStr);
41    notFM.put("string", notStr);
42    canFM.put("length", Integer.toString(3));
43    notFM.put("length", Integer.toString(3));
44 
45    try {
46      outputAS.add(start, middle, "Token", canFM);
47      outputAS.add(middle, end, "Token", notFM);
48    }
49    catch (InvalidOffsetException e) {
50      /* This should never happen */
51      e.printStackTrace();
52    }
53 
54    outputAS.remove(cannot);
55 
56      }
57    }
58  }

我已经尝试了一系列编译器的变体，JDK版本，甚至尝试了GATE7.1而不是8.0。

目前使用的是Java版本1.7，因为我读到jasper-compiler-jdt.jar在Java 1.8上不能很好地工作。编译器版本也是1.7。

我知道问题一定与编译器jar类型有关，但它们似乎都在GATE本身和Eclipse之间匹配。GATE GUI指向正确的JDK。使用jasper编译器生成的: gate/util/compilers/eclipse/jdt/internal/compiler/env/INameEnvironment :java.lang.NoClassDefFoundError

因此，我不得不包含一个gate-compiler-jdt jars，它会产生上面的第一个错误。

据我所知，所有其余的jar文件都正确地与GATE8.0关联。谁能告诉我错误可能在哪里，或者哪组编译器是正确的？

提前感谢！

正如您和Ian所说，我是通过在POM.XML中设置'gate- compiler -jdt‘的编译器版本来使用GATE 8.1工作的，方法与GATE_HOME/lib中的版本类似

'C:\Program Files\GATE_Developer_8.2\lib'
