I had my latest build failed - I had built just fine a few days ago. I thought maybe there was an update so I went to the solar2d site and the download link was not working. The build error was;
19:00:52.337 > Task :App:prepareLintJar
19:00:52.337
19:00:52.337 > Task :App:lintVitalRelease
19:00:52.337 C:\Users\User\AppData\Local\Temp\Corona Labs\CLtmpa13372\template\app: Error: commons-logging defines classes that conflict with classes now provided by Android. Solutions include finding newer versions or alternative libraries that don’t have the same problem (for example, for httpclient use HttpUrlConnection or okhttp instead), or repackaging the library using something like jarjar.

[DuplicatePlatformClasses]
19:00:52.337
19:00:52.337 Explanation for issues of type “DuplicatePlatformClasses”:
19:00:52.337 There are a number of libraries that duplicate not just functionality of
19:00:52.337 the Android platform but using the exact same class names as the ones
19:00:52.337 provided in Android – for example the apache http classes. This can lead
19:00:52.337 to unexpected crashes.
19:00:52.337
19:00:52.337 To solve this, you need to either find a newer version of the library which
19:00:52.337 no longer has this problem, or to repackage the library (and all of its
19:00:52.337 dependencies) using something like the jarjar tool, or finally, rewriting
19:00:52.337 the code to use different APIs (for example, for http code, consider using
19:00:52.337 HttpUrlConnection or a library like okhttp).

I just fixed download link or solar2d site.
Are you using any plugins?
well I found the github download and got the latest version down - and it worked! So no idea why it stopped working, but all fixed now.
