Go to the libraries folder and create an xml file with the same name as the 'a' file (without the lib prefix).
The content of this file should be:
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<root>
<doclet-version-NOT-library-version>1.00</doclet-version-NOT-library-version>
<version>1</version>
<!-- this is optional. It allows you to add more references<dependsOn>AppTracker</dependsOn> -->
</root>
