groovy 中的 Repast ReLogo 代码编译失败

Question

我在 ReLogo 中编写了一个 Repast 程序。基本上，我按照 this 文档第 19 页的说明复制粘贴代码。

我在 Ubuntu 18.04，我按照说明安装了 Repast Symphony。我的 java 版本基本上是 oracle JDK-8:-

java version "1.8.0_181"
Java(TM) SE Runtime Environment (build 1.8.0_181-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.181-b13, mixed mode)

然后我尝试运行按照第 20 页上的说明编写代码，但项目无法编译并出现此错误：-

Exception in thread "AWT-EventQueue-0" java.lang.Error: Unresolved compilation problems: 
    The annotation @ReLogoBuilderGeneratedFor is disallowed for this location

我的 groovy 编译器设置如下：

我有两个建议供您尝试。

从 PDF 文档复制和粘贴可能会产生意外影响，因此请尝试直接输入代码。您也可以尝试运行 Zombies_Demo 示例模型，发现here. You can follow the instructions to import the example model in the "Linux users and Unix-related system users" section here。如果您仍然发现问题...
尝试将 Groovy 版本更改为 2.4。

如果这些建议有帮助，请告诉我们。
