JavaFX 8 ant 构建错误代码太大

Question

我在 eclipse 上开发；我的代码目前编译并直接从 eclipse 中运行查找(通过执行 Run As Java Application)——我在此过程中没有遇到任何错误。

然后我尝试生成 Ant build.xml 并尝试编译它，这以 BUILD FAILED 终止；下面是构建的输出:

似乎产生错误的类只是对 IcoMoon 字形集(大约 2000 个字形/字符关联)的 JavaFX FontAwesome Glyph 类(定义 here)的现有代码的改编。

这是违规类代码的链接:https://gist.github.com/autronix/51322d3c24f21e6755a5

由于代码直接在eclipse中编译运行良好，我想知道我是否在ant编译器中遗漏了任何参数。我一直无法弄清楚如何解决这个问题。

如有任何帮助，我们将不胜感激。

谢谢

Java 中的方法仅限于 64k 字节码。一旦超过限制，java 编译器将抛出错误

error: code too large

所有静态初始化都在一个方法中完成，因此有可能因此而发生。

在eclipse中运行良好，因为eclipse有自己的编译器。
