Builds of Android package fail with 'apply' message after updating SDK - how to fix?

I recently upgraded the Android SDK on our build machine, and now Android builds using Ant fail with the obscure message:

The <apply> type doesn't开发者_如何学编程 support the nested "path" element.

Our build.xml is the standard one generated by Android tools, and we automatically run

android update project -p .

before Ant runs the debug task. The error message appears during the -dex phase of the build process.

Since this buildfile is using one of the standard Android templates, I'm not sure what's causing this change in behavior. Any ideas?

Never mind, I figured it out. Seems that Android version 8 or higher now require you to have ant 1.8 or higher (I was still using 1.6.5). The fix was simply to upgrade my ant installation to the latest version.
