title: Conversion to Dalvik format failed with error 1 adt r18
body: <p>although there are many questions with a similar title, I could not find the solution to this issue.</p>
  
  <p>I have an Android project in Eclipse which references ActionBarSherlock 4.0.2 as Android library. In addition, I have added the JARs for ACRA and Google Analytics in the /libs folder. The support v4 jar is taken from ABS libs.</p>
  
  <p>The project's Java Build Path looks like this

  <p>When exporting through the wizard I get the "Conversion to Dalvik format failed with error 1" error.</p>
  
  <p>Cleaning, removing all Android Dependencies and clicking on Fix Project Properties and cleaning does all not work.</p>
  
  <p>Any idea?</p>
  
  <p><strong>EDIT:</strong></p>
  
  <p>I missed some info: I'm doing this on Mac OS 10.6.8, Eclipse Indigo, Android SDK Tools r19 and ADT plugin v18. </p>
  
  <p>project.properties file includes the proguard.cfg file: commenting it does avoid the issue.</p>
