Hello Appinventors,
Today when I was testing a new component which i have added in my local AI2 i encountered an error while building the apk.
Here is the log of the buildserver..

I understood from the error that the required library appcompat-resources-1.2.0.aar is missing but i have already added them in both component/build.xml as well as my component's code.

<copy toFile="${public.deps.dir}appcompat-resources-1.2.0.aar" file="${lib.dir}/material/appcompat-resources-1.2.0.aar" />

@UsesLibraries(libraries = "material-1.6.1.jar,material-1.6.1.aar,appcompat-resources-1.2.0.aar")

Any help will be appreciated.
