java - 如何在J2ME应用程序中编写build.xml？

Question

我开发了一个j2me应用程序，它运行良好。

在我的应用程序中，我有 build.xml，当我运行此 build.xml 时，它会生成一个 jar 和 jad 文件。

但是这里构建失败，但创建了 jar 和 jad，当我运行该 jad 时，应用程序未运行。

请帮我如何在j2me中编写build.xml，以下是我的build.xml

<project name="DEMO" default="build" basedir=".">

这是我的 build.xml 的输出

如何成功构建这个？

感谢和问候

这与build.xml无关。您正在链接的是通用库 LWUIT.jar，而不是您想要的 LWUIT MIDP 版本。
