我是 Groovy 和 Java 的新手。我正在尝试编译一个枚举，以便可以在多个其他 Groovy 脚本中使用它。
这是枚举:
package branchformatter
enum ColorSequence
{
COLUMNS,
WHEEL
}
当我尝试使用 groovyc 编译它时，它似乎编译时没有错误，但是当我将其导入另一个脚本并尝试运行第二个脚本时，我收到以下错误:
the number of constructors during runtime and compile time for branchformatter.ColorSequence do not match. Expected -1 but got 2
我尝试使用 Groovy Console 编译枚举并得到以下异常:
java.lang.InstantiationException: branchformatter.ColorSequence
奇怪的是，如果我将枚举定义直接复制并粘贴到第二个脚本中，而不是尝试导入它，第二个脚本就可以正常工作。所以枚举似乎没有什么根本性的错误。
我正在运行 Groovy 2.2.1 和 Java 1.7.0_51。我正在尝试从 Freeplane 1.2.23(思维导图应用程序)中执行第二个脚本。
编辑:这是我在第二个脚本中使用它的方式:
import branchformatter.ColorSequence
def colorSequence = ColorSequence.WHEEL
if (colorSequence == ColorSequence.COLUMNS)
{
...
}
编辑2，回应chrylis询问反编译的枚举是什么样子的:还没有安装JDK，只有JRE，而且看起来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，如本答案所述: https://stackoverflow.com/a/272595/216440 。这是反编译枚举类文件后的输出:

最佳答案
在我看来，这是由 Groovy 和/或 Java 版本的差异引起的。我认为这个问题可能是由于您使用 groovyc 2.2.1 手动编译它，并且 Freeplane 试图使用它自己的内部 groovy 库运行它，该库可能位于不同的版本上。
http://freeplane.sourceforge.net/wiki/index.php/Scripting:_Update_Freeplane%27s_Groovy_version
这表示 Freeplane 附带了 groovy 1.8.0。我会尝试更新 Freeplane 以使用 groovy 2.2.1，或者自己回退到 1.8.0，看看是否可以解决问题。
有两件事作为一般说明: 第一:任何时候您看到“构造函数数量错误”或“不兼容的类更改”错误，通常表明存在 java 和/或 groovy 版本问题。根据我的经验，十分之九这就是问题所在。
如果您有过 java/groovy 的经验，那么第二件事是非常基本的，但无论如何我都会提到它，因为您说您对两者都是新手。如果您正在运行 Groovy 脚本，则无需预编译它。 Groovy shell 会在评估脚本时为您执行此操作。然后您将始终确保它是使用运行它的同一版本的 groovy 进行编译的。
