Adding JsonPath in Android Studio causes non-zero exit value 2 error

When I add the JsonPath library to my Android Studio (1.4) project I get an error as following:

Error:Execution failed for task ':app:dexDebug'. \>
com.android.ide.common.process.ProcessException:
org.gradle.process.internal.ExecException:
Process 'command 'C:\Program Files\JDK_64_bit\bin\java.exe'' finished with 
non-zero exit value 2

(I added the library via File > Project Structure > Dependencies > Library Dependency > com.jayway.jsonpath:json-path:2.0.0)

Trying to add MultiDex support for the app as suggested in a few other questions results in a different error:

Error:Execution failed for task ':app:packageAllDebugClassesForMultiDex'. \>
java.util.zip.ZipException: duplicate entry:
org/objectweb/asm/AnnotationVisitor.class

The external libraries in my project list both asm-1.0.2 and asm-3.3.1 but removing one or both does not solve my problem.

Thank you very much in advance!
