I\'m using Tika and I realized that each time the jar file is downloaded and placed in Temp folder
Retrieving http://search.maven.org/remotecontent?filepath=org/
To resolve this problem you should add an environment variable to the tika server jar and specify the path folder which contains the tika jar file.
TIKA_SERVER_JAR = 'PATH_OF_FOLDER_CONTAINING_TIKA_SERVER_JAR'.
