Does the ADT plugin automatically create an ant build file?

问题

I created an Android project a few months ago and now have to automate the build process with Hudson. The Android dev guide mentions a build.xml file that gets created when you generate a project (http://developer.android.com/guide/developing/other-ide.html) but I dont see one in my project. Will I have to create this by hand or can I run a command to generate it?

回答1:

The ADT plugin doesn't generate an Ant file.

The android command will generate an Ant file when you create a new project from the command line by calling android create project. You could create an example project and copy the build.xml, build.properties and local.properties files from that directory.

Alternatively, you can just copy the build.xml template directly from $ANDROID_HOME/tools/lib/build.template then just change the project name.

Then just create a build.properties file — it's where you place any Ant property overrides.
Also you need a local.properties file, but don't check that into source control — this is where you specify your $ANDROID_HOME directory by setting the sdk.dir property.

The following will generate a build.xml file as well as a local.properties file if one does not exist in your project.

android update project --path <path to your project directory>

回答3:

You can use these steps below:

• Open command line
• Go to: <path/to/android sdk/tools>
• Run: $ android update project --path /path/to/my-project => it will generate build.xml and local.properties

• Create file: ant.properties with two line below

  key.store=path/to/keystore
  key.alias=alias name
  

• Open build.xml and rename project name if need

• Run as ant build (debug, release, etc...)
