Warbler 可执行文件无法启动

Question

我在使用 warbler 打包我的 JRuby 应用程序并运行它时遇到了一些问题。

我创建了一个简单的 sqlite3 应用程序，其中一个模型在通过 jruby -S rails s 运行时运行良好。

但是，如果我尝试使用 jruby -S warble executable war 打包它，打包的 Winstone 服务器会崩溃

这是从哪里来的，我该如何运行？

这是由于 JRuby 1.5.5 和更早版本中的一个错误影响在 Windows 和包含空格的路径中运行可执行 jar。请参阅JRUBY-4774 或WARBLER-15。

尝试将 JRuby 升级到 1.5.6 (gem update jruby-jars)，重建 war 文件，然后重试。
