When using tika-1.4 getting this:

Caused by: java.lang.NoClassDefFoundError: net/sf/cglib/core/DebuggingClassWriter

Added these two lines into BuildConfig.groovy:

compile ("org.apache.tika:tika-core:1.4")
compile ("org.apache.tika:tika-parsers:1.4") {excludes "tika-core"}

If I don't exclude tika-core from tika-parsers, I'm getting 2 versions of tika-core (version 1.0 pulled by vorbis-java-tika dependency) and version tika-core version 1.4.

If I replace tika version to be 1.3, exception is gone.

UPDATE 1

This solution seems works:

compile ("org.apache.tika:tika-core:${tikaVersion}")
compile ("org.apache.tika:tika-parsers:${tikaVersion}") { excludes "tika-core", "commons-codec", "commons-logging", "slf4j-api" }

This may or may not be the issue you're seeing -- we're working with tika 1.5 (snapshot). That version pulls in asm-debug-all, which was the cause of our troubles (similar stacktrace to yours). Try using 'asm-debug-all' in your tika-parsers excludes instead of 'tika-core'.
