Java grails应用程序中的上下文为只读错误

我试图使用grails应用程序中的示例使用de GROBID JAVA API。 以下JAVA代码（Netbeans）运行良好：

public static void main(String[] args) {
    // TODO code application logic here

    String pdfPath = "/home/jose/plantilla_Informatica_2015 (ok).pdf";
    String pathGHome = "/home/jose/GROBID_COMPILED/grobid-home";
    String pathGProp = "/home/jose/GROBID_COMPILED/grobid-home/config/grobid.properties";

    try {
        MockContext.setInitialContext(pathGHome, pathGProp);
        GrobidProperties.getInstance();

        Engine engine = GrobidFactory.getInstance().createEngine();
        BiblioItem bi = new BiblioItem();

        String doc = engine.processHeader(pdfPath, false, bi);
        System.out.println(doc);

    } catch (Exception ex) {
        Logger.getLogger(GROBID.class.getName()).log(Level.SEVERE, null, ex);
    }
    finally{
        try{
            MockContext.destroyInitialContext();
        }
        catch(Exception ex){
            Logger.getLogger(GROBID.class.getName()).log(Level.SEVERE, null, ex);
        }
    }

}

当我向grails复制具有相同依赖项集的相同代码时， 然后将grobid-core.jar放在文件夹lib中，它会告诉我错误：

###编辑#####

如果我构建同一个应用程序的war并使用

grails run-war target/GROB-0.1.war

它工作得很好

会发生什么？ 有什么帮助吗？

感谢您的建议。

作为第一步，您是否添加了grobid作为依赖项<代码>编译'org.grobid:grobid核心：0.3.4'该异常来自Tomcat。您可以在这里看到：代码运行时是否使用Tomcat？我在lib文件夹中复制了grobid的最新版本（称为grobid-core-0.4.0-SNAPSHOT.jar），在BuildConfig.groovy中添加了compile“org.grobid:grobid-core:0.4.0”，控制台打印：解决获取依赖项的错误：读取org的工件描述符失败。grobid:grobid core:jar:0.4.0（使用--stacktrace查看完整跟踪）@EmmanuelRosa是的，我正在使用tomcat，如何修复此错误？谢谢你的时间！作为第一步，您是否添加了grobid作为依赖项<代码>编译'org.grobid:grobid核心：0.3.4'该异常来自Tomcat。您可以在这里看到：代码运行时是否使用Tomcat？我在lib文件夹中复制了grobid的最新版本（称为grobid-core-0.4.0-SNAPSHOT.jar），在BuildConfig.groovy中添加了compile“org.grobid:grobid-core:0.4.0”，控制台打印：解决获取依赖项的错误：读取org的工件描述符失败。grobid:grobid core:jar:0.4.0（使用--stacktrace查看完整跟踪）@EmmanuelRosa是的，我正在使用tomcat，如何修复此错误？谢谢你的时间！
