對,所以我終於想出了一個解決方案,我在三個平臺上成功測試過。
這兩個神奇的組件是jar-in-jar-loader和一個合適的構建腳本。
與評論構建腳本可以在這裏找到:
<project name="RandomApp" basedir="." default="clean-build">
<property name="src.dir" value="src" />

<target name="clean-build" depends="clean,jar" />
</project>
什麼它基本上是定義一個基類路徑沒有任何 SWT庫。然後它使用基礎類創建特定於平臺的類路徑並添加適當的平臺SWT庫。
jar
任務然後使用這些類路徑和jar-in-jar-loader爲每個平臺創建一個單獨的jar。
而就是這樣,它是一種爲每個(支持的)平臺生成罐子的完全自動化的方式。
我創建了一個示例項目,人們可以下載並測試。這對於多平臺應用程序來說是一個簡單的起點。

我已經設法通過適當利用macrodef

嘿的,很高興顯著縮短ant腳本看到有人試圖彙總所有這些信息集中在一個地方。幹得不錯! – Nobody
