variableReplace显示错误

Question

我已经到了docx4j文件的GitHub存储库并下载了VariableReplace。当我将这个文件复制到netbeans中时，我在第86行发现了一个错误（Cannont find symbol）。

下面是代码：

* 
* You're encouraged to investigate binding content controls 
* to an XML part. There is org.docx4j.model.datastorage.migration.FromVariableReplacement 
* to automatically convert your templates to this better 
* approach. 
* 
* OK, enough preaching. If you want to use VariableReplace, 
* your variables should be appear like so: ${key1}, ${key2} 
* 
* And if you are having problems with your runs being split, 
* VariablePrepare can clean them up.

     // Save it 
     if (save) { 
      SaveToZipFile saver = new SaveToZipFile(wordMLPackage); 
      saver.save(outputfilepath);

      System.out.println(XmlUtils.marshaltoString(documentPart.getJaxbElement(), true, 
        true)); 
     } 
    } 

} 

有谁知道为什么我收到此错误？

这里有几张图片：

编辑：

我没有得到任何直接的错误，但是当我运行下面的代码，我得到这些错误：

Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/log4j/Logger 
    at org.docx4j.openpackaging.Base.<clinit>(Base.java:42)

我只是想出了问题:)。我正在使用旧样本。

这是新代码：
