我是Groovy和Java的新手。我试图编译一个枚举，所以我可以在多个其他Groovy脚本中使用它。无法编译Groovy枚举
这里的枚举：
package branchformatter
enum ColorSequence
{
COLUMNS,
WHEEL
}
当我尝试用groovyc它似乎编译没有错误，但是当我将其导入到另一个脚本，并尝试运行第二个脚本，我收到以下错误编译：
the number of constructors during runtime and compile time for branchformatter.ColorSequence do not match. Expected -1 but got 2
我试图编译使用Groovy控制台枚举，并得到了以下异常：
java.lang.InstantiationException: branchformatter.ColorSequence
奇怪的是，如果我直接将枚举定义复制并粘贴到第二个脚本中，而不是尝试导入它，则第二个脚本可以正常工作。所以这个枚举似乎没有任何根本性的错误。
我正在运行Groovy 2.2.1和Java 1.7.0_51。我试图从Freeplane 1.2.23（思维导图应用程序）中执行第二个脚本。
编辑：这是我如何使用它的第二个脚本：
import branchformatter.ColorSequence
def colorSequence = ColorSequence.WHEEL
if (colorSequence == ColorSequence.COLUMNS)
{
...
}
EDIT 2，响应chrylis要求见反编译枚举的样子：有没有安装了JDK，只安装了JRE，看起来JDK是一个巨大的安装，所以可能需要一段时间。相反，我下载了JD-GUI，如本答案中所述：https://stackoverflow.com/a/272595/216440。下面是输出后，反编译枚举类文件：

}
}
编辑3：javap的-c -p ColorSequence的输出。请注意，输出已经被截断，因为它超过了最大长度后：

你可以发布'javap -c -p ColorSequence'的输出吗？ – chrylis
如果这种反编译是准确的（反汇编仍然更有用），它看起来像'groovyc'处理枚举的一个主要错误。 Java枚举特别不应该具有公共构造函数（有几个特定的实例）。下一步我会试着编译你的Java枚举（因为你没有涉及任何行为），并在Groovy中使用它。 – chrylis
@chrylis：谢谢。已经下载了JDK和Eclipse，并试图去掌握它。我会尝试在枚举类文件上使用javap，但将Java编译为Groovy枚举的想法可能是解决方案。下班后必须尝试一下（一旦我已经想出如何使用Eclipse）。 –
