java - 重新编译jodatime？

Question

这是我第一次使用 jodatime，我遇到了一个 stackoverflow 错误，我不知道如何修复。我正在创建一个 Android 应用程序，它需要能够显示创建 sqlite 记录到今天之间的天数。据我所知，除了 jodatime 之外，一切都工作正常。我在构建项目时遇到此错误

[2010-08-10 02:08:50 - Grow Journal Beta] processing org/joda/time/DateTimeUtils.class...
[2010-08-10 02:08:50 - Grow Journal Beta] processing org/joda/time/DateTimeZone$1.class...
[2010-08-10 02:08:50 - Grow Journal Beta] warning: Ignoring InnerClasses attribute for an anonymous inner class that doesn't come with an associated EnclosingMethod attribute. (This class was probably produced by a broken compiler.)
[2010-08-10 02:08:50 - Grow Journal Beta] processing org/joda/time/DateTimeZone$Stub.class...

This is the logcat:

08-13 22:12:11.823: ERROR/AndroidRuntime(6537): Uncaught handler: thread main exiting due to uncaught exception

After looking around a bit i figure i just need to recompile the jodatime binary my self. I've been using eclipse, I created a new project, and imported the jodatime source. When I attempt to compile I get this in the console:

Usage: java org.joda.time.tz.ZoneInfoCompiler <options> <source files>

可能的选项包括: -src 指定读取源文件的位置 -dst 指定生成文件写入位置

不太确定从这里该去哪里。任何帮助将不胜感激。感谢您抽出时间。

DateTimeZone.class 源是 Here

Answer 1

有问题的递归显然是在 DateTimeZone.getDefault 和 DateTimeZone.forID 之间。然而，堆栈行号似乎与我看到的 Joda 源代码 here 不一致。 。在该代码中，DateTimeZone.getDefault() 方法不会查看系统属性……这些内容发生在静态初始值设定项中。

Android 代码库似乎使用了 JodaTime 的调整版本。

无论如何，调用 JodaTime.setDefault(...) 看起来可能是一种解决方法。另外，检查“user.timezone”系统属性是否已设置。

(我不认为重新编译/使用标准 JodaTime 是正确的策略。Android 的调整......无论它们是什么......可能是有原因的。)

编辑

重新审视这一点，发现这是某些平台(Android、Google-Apps)上 JodaTime 1.6.1 中的错误。问题跟踪器显示它已在 JodaTime 1.6.2 中修复。
