Unable to build Eclipse library projects after ADT update
<p>I have a main project (mainapp) I am developing for Android under Eclipse. It uses the facebook-android-sdk library (fblib) which is a separate Eclipse project with it's project properties checked as "Library". Under the project properties > android section for mainapp, I have fblib added as a library. everything works fine. </p>

<p>I needed to create a new version of mainapp which uses different database files (assets subdirectory). To do this, I created a new Eclipse project (newapp) and setup mainapp as a library under project properties > android. </p>

<p>Everything was working fine until the latest ADT update. I am getting errors trying to build/run newapp (Conversion to Dalvik format failed with error 1). If I go to mainapp and uncheck "Library" from project properties > android, I can build mainapp as a regular application and it seems to work just fine.</p>

<p>I've searched for multiple jar files in project directories, updated proguard to 4.8beta, deleted/added jars to the build path, removed exports, added exports, deleted dependencies, added "lib" directories, cleaned, restarted, rebooted and pretty much anything else google would turn up, but to no avail. </p>

<p>It was all working fine with ADT 16 so I'm really confused here. Has adding a library project to an application, which also incorporates a library project, become somehow deprecated? I just can't seem to get this working.</p>
