如何将 Eclipse Android 项目转换为使用 Ant 进行构建? [英] How to convert an Eclipse Android project to use Ant for build?

问题描述

我在 Eclipse 中有一个 Android 项目，我想转换为使用 Ant 来构建.

I have an Android project in Eclipse I would like to convert to be built with Ant instead.

我怎样才能做到这一点?我曾尝试导出 Ant 构建文件，但我很确定这不会起作用(在使用导出的文件运行 ant 时也不会).我对 Ant 也不太了解，所以一些解释也会有所帮助.

How can I achieve this? I have tried exporting an Ant build file but I'm pretty sure that's not going to work (nor does it when running ant with the exported file). I do not know much about Ant either so some explanation would also help.

现在我似乎已经设法创建了所需的构建文件，但我需要添加像 admob.jar 这样的项目库，以便 ant 看到并用于构建.因为我收到以下错误

now I seem to have managed to create the needed build file but I need to add the projects libs like admob.jar to be seen by ant and used to build. as I am getting the following error

推荐答案

Running android update project -p . 在命令行上，在您的项目的基本文件夹中将创建必要的 build.xml 和支持文件一个 Ant 构建.

Running android update project -p . on the command line, in the base folder of your project will create the necessary build.xml and supporting files for an Ant build.
