Question

我正在尝试从此链接（https://github.com/mxmlnkn/rootbeer1）运行Rootbeer主版本。它与类似问题（Unable to cast a class error）中使用的版本（更新版本）略有不同。

我已经成功编译了它，并创建了Rootbeer.jar（按照说明打包）。

我收到以下错误。您能建议如何解决吗？由于此错误，我无法运行任何示例。我确实尽了所有我能想到的尝试，但无法克服此错误。任何帮助，将不胜感激。

ScalarAddApp示例的输出，如果在Eclipse中执行：

start array[0]: 0
start array[1]: 1
start array[2]: 2
start array[3]: 3
start array[4]: 4
start array[5]: 5
start array[6]: 6
start array[7]: 7
start array[8]: 8
start array[9]: 9

Exception in thread "main" java.lang.ClassCastException: ScalarAddKernel cannot be cast to org.trifort.rootbeer.runtime.CompiledKernel

    at ScalarAddApp.multArray(ScalarAddApp.java:28)
    at ScalarAddApp.main(ScalarAddApp.java:53)

在命令提示符下执行的命令输出：
