【问题描述】：
Modisco java 模型的 Java 源代码生成有问题。
我在 Modisco 文档中使用了以下指南：
https://help.eclipse.org/2018-12/topic/org.eclipse.modisco.java.doc/mediawiki/java_generation/user.html?cp=67_0_1_1_2
首先，我在工作区中导入了插件org.eclipse.gmt.modisco.java.generation
然后我在 src 文件夹中添加了一个类，如下所示：
import java.io.File;
import java.io.IOException;
import java.util.*;
import org.eclipse.emf.common.util.URI;
import org.eclipse.gmt.modisco.java.generation.files.GenerateJavaExtended;
public class Generation {
public static void main(String[] args) throws IOException {
GenerateJavaExtended javaGenerator = new GenerateJavaExtended(URI.createFileURI("mymodel.xmi"),
new File("myOutputFolder"), new ArrayList<Object>());
javaGenerator.doGenerate(null);
}
}
但是当我将此代码作为 Java 应用程序运行时，我收到此错误：

如何将我的 Java 模型转换回原始 Java 源代码？
我用过的工具：
- Eclipse 建模工具 2018-12 (4.10.0)
- MoDisco SDK (1.2.0)
- JRE 1.8.0_202
