如何使用ant构建android

Question

我想为我的项目设置一个ant build.我找到了一个教程,说我需要编写以下命令才能为ant build做准备:

android update project -p 

然后我得到了结果

Updated local.properties
Updated file ./proguard-project.txt
It seems that there are sub-projects. If you want to update them
please use the --subprojects parameter.

所以,如果我尝试

android update project -p . --subprojects

然后我得到:

Updated local.properties
Updated file ./proguard-project.txt
Error: The project either has no target set or the target is invalid.
Please provide a --target to the 'android update' command.

如果我试试

ant release

我明白了

sdk.dir is missing. Make sure to generate local.properties using 'android update project' or to inject it through an env var

有人可以帮助我用ant建立项目.谢谢

我也有同样的问题.
我的问题问题通过以下命令解决了.

android update project --path . --subprojects --target android-19

ANT会自动将您的sdk.dir设置为正确的.
不要在local.properties中放置任何内容.
