Question

成功将一个成熟的jruby servlet项目从Ubuntu 12.04移植到Fedora 14之后，一切工作都达到了构建servlet的程度。

jruby -S warble compiled

工作正常，但随后

jruby -S warble war

甚至只是：

jruby -S warble -T

的产率：

我正在跑步：

jruby 1.6.7.2（ruby-1.8.7-p357）（2012-05-01 26e08ba）（OpenJDK Server VM 1.6.0_20）[linux-i386-java]

在Fedora 14下的i686机器上。最新的JRuby尚未成熟到这个项目 - 我已经尝试过了。

我已经尝试重新安装warbler-1.3.5并将其升级到1.3.6并在本地重建它但我总是得到同样的错误。

我可以找到同样的错误，可以追溯到在线搜索的2年，但没有后续讨论，没有解决方案。任何帮助都将深表感谢。
