如何在Mac OS X上获得JDK 1.5 [英] How to get JDK 1.5 on Mac OS X

问题描述

我必须为仍在运行JDK 1.5的遗留应用程序编写一些代码。不幸的是，看起来OS  X实际上并没有安装1.5 JDK;它只链接到1.6：

I've got to write some code for a legacy application that is still running JDK 1.5. Unfortunately, it looks like OS X doesn't actually have a 1.5 JDK installed; it just links to 1.6:

/System/Library/Frameworks/JavaVM.framework/Versions $ ls -l
lrwxr-xr-x  1 root  wheel    5 Apr 26 11:53 1.3 -> 1.3.1
drwxr-xr-x  3 root  wheel  102 Feb 11 15:33 1.3.1
lrwxr-xr-x  1 root  wheel   10 Apr 26 11:53 1.4 -> CurrentJDK
lrwxr-xr-x  1 root  wheel   10 Apr 26 11:53 1.4.2 -> CurrentJDK
lrwxr-xr-x  1 root  wheel   10 Apr 26 11:53 1.5 -> CurrentJDK
lrwxr-xr-x  1 root  wheel   10 Apr 26 11:53 1.5.0 -> CurrentJDK
lrwxr-xr-x  1 root  wheel    5 Apr 26 11:53 1.6 -> 1.6.0
drwxr-xr-x  7 root  wheel  238 Apr 26 11:53 1.6.0
drwxr-xr-x  8 root  wheel  272 Apr 26 11:53 A
lrwxr-xr-x  1 root  wheel    1 Apr 26 11:53 Current -> A
lrwxr-xr-x  1 root  wheel    3 Apr 26 11:53 CurrentJDK -> 1.6

听起来像是来自 http://developer.apple.com/java/faq/ Java是操作系统更新的一部分......我在 Mac  OS  X  v10.6.3 （Snow  Leopard）。有没有办法在这个操作系统版本上安装一个实际的1.5 JDK？

It sounds like from http://developer.apple.com/java/faq/ that Java is part of the OS update...I'm on Mac OS X v10.6.3 (Snow Leopard). Is there a way to get an actual 1.5 JDK installed on this OS version?

或者在我能做之前我是否需要尝试找到旧版本的OS  X这项工作？

Or do I need to try and find an old version of OS X before I can do this work?

推荐答案

如果您在Eclipse或其他IDE中编写代码，您应该能够将其配置为目标1.5合规。

If you're writing code in Eclipse or potentially some other IDE, you should be able to configure it to target 1.5 compliance.

如果您直接使用javac，您可以尝试 -source 1.5 和/或 -target 1.5 javac选项，这可能足以满足您的需求？ 1.6 JDK应该能够生成符合1.5的代码。

If you are using javac directly, you could try the -source 1.5 and/or -target 1.5 javac options, which may be sufficient for what you're doing? The 1.6 JDK should be able to produce 1.5-compliant code.
