用于检查源代码对特定 Java 版本的依赖性的工具
是否有一种快速方法（例如工具）可以从源代码（或者甚至从编译的类）检测应用程序的哪些部分调用仅在特定 Java 版本中实现的 Java API 方法？ （例如，我的应用程序的哪些部分是特定于 Java6 的）
我不一定希望跳过所有 ClassMismatchErrors 并避免尝试错误方法。假设我只想记录应用程序的哪些部分如果是为 Java6 编写的，则无法工作，并且我想在 JDK 版本 5 中运行它。
有这样的事吗？谷歌这次没有帮助，我也没有在这里找到任何解决方案（确实是一种罕见的情况：）
Is there a quick way (e.g. tool) to detect, from the source (or maybe even from compiled classes), which parts of an application call Java API methods that are only implemented in a specific Java version? (e.g. which parts of my app are Java6-specific)
I don't necessarily want to hop through all ClassMismatchErrors and avoid the trial-and-error-method. Let's say I only want to document which parts of an application won't work if they were writte for, e.g., Java6 and I want to run it in a version 5 JDK.
Is there something like this? Google did not help this time, nor did I find any solution here (a rare case indeed:)

Animal Sniffer 可能对此有所帮助，尤其是它的 Maven 插件。

如果我理解正确的话，你所描述的对我来说听起来不是一个好主意。
听起来你想在 JDK 6 上构建一些库（指定 -target 1.5），但让它在 JDK 5 上运行，并且只是到处都有某些类或方法，这是行不通的（因为它们需要一个仅限 Java6 的 API） 。我不会这样做。 应该工作的方法可能仍然会触发加载一个类，该类本身包含一些对Java 6中新类的引用，以及一个
错误将被抛出。如果您只选择哪个版本是您的最低支持版本并接受它，那就更好了。
If I understand you correctly, what you're describing doesn't sound like a very good idea to me.
It sounds like you want to build some library on JDK 6 (specifying -target 1.5), but let it be run on JDK 5 and just have certain classes or methods here and there just not work (because they needed a Java6-only API). I wouldn't do this. A method which should work might still trigger a class to be loaded which itself contains some reference to a class that's new in Java 6, and an
Errorwill be thrown.It's much better if you just choose which version is your minimum supported version and live with that.
