如何转换Eclipse Android项目以使用Ant进行构建？

Question

我在Eclipse中有一个Android项目我希望将其转换为使用Ant构建.

我怎样才能做到这一点？我已经尝试导出一个Ant构建文件,但我很确定它不会起作用(当使用导出的文件运行ant时也不行).我不太了解Ant,所以一些解释也会有所帮助.

编辑:现在我似乎设法创建了所需的构建文件,但我需要添加项目库像admob.jar,以便被ant看到并用于构建.因为我收到以下错误

Answer 1

android update project -p .在命令行上运行,在项目的基础文件夹中将为build.xmlAnt构建创建必要和支持的文件.

Answer 2

以下是为eclipse中的任何项目创建build.xml的步骤

文件 - >导出 - >常规 - > Ant Buildfiles并选择创建构建文件所需的项目.
