从同一代码库编译J2ME和J2SE应用程序的最佳方法是什么？(What is the best way to compile J2ME and J2SE apps from the same codebase?)

 我正在尝试为J2ME和J2SE构建一个应用程序。 演示代码显然会有所不同，但我希望尽可能保持逻辑的共性。 
 
 我的计划是使用Ant或Antenna的预处理器来选择J2ME或J2SE Graphics对象，该类是我的逻辑和显示代码之间的唯一交集。 我需要的是在Ant / Antenna构建任务期间在一些文件中交换一行或两行导入。 
 
 我想就如何设置这个问题提出一些建议。 
 
 我目前有两个Eclipse项目，一个J2ME和一个J2SE。 我对如何设置预处理器有几点想法： 
 
 
 
 将J2SE代码作为缺省值，并且仅预处理J2SE代码以交换J2SE特定的导入 
 
 
 对J2ME和J2SE项目使用Antenna预处理器 
 
 
 使用Ant文本替换来进行必要的源修改 
 一世。 看起来很难设置正确 
 II。 感觉有点笨拙 
 III。 看起来最不好，因为我认为自己不需要使用比一些条件导入更多的东西。 
 
 
 有没有人有这种事情的经验？ 一些建议将非常感谢。 

I'm trying to build an app for both J2ME and J2SE. The presentation code will obviously be different, but I'm hoping to keep the logic common, as much as possible.
 
My plan is to use Ant or Antenna's preprocessor to select either the J2ME or J2SE Graphics object, with that class being the only intersection between my logic and display code. All I need is to swap a line or two of imports in a few files during my Ant/Antenna build task.
 
I'd like some advice on how to get this set up.
 
I've currently got two Eclipse projects, one J2ME and one J2SE. I have a couple ideas for how I could set up the preprocessor:
 
 
 
Have the J2SE code be the default, and only preprocess the J2SE code to swap in the J2SE specific imports
 
 
Use the Antenna preprocessor for both the J2ME and J2SE projects
 
 
Use Ant text substitution to make the necessary source modifications
 
i. looks hard to get set up right
 ii. feels a bit kludgy
 iii. seems least bad, because I don't see myself ever needing to use much more than a few conditional imports.
 
 
Has anyone had experience with this sort of thing? Some advice would be much appreciated.
