Download Apache Tika

The latest release is Apache Tika 4.0.0. The 3.x line (3.3.2) remains supported and continues to receive bug fixes and dependency upgrades -- see the "3.x Maintenance Line" section below.

Latest Release: 4.0.0

Tika 4.x ships zip distributions, not runnable jars. tika-app, tika-server-standard and tika-eval-app are zip archives containing a thin launcher jar and an adjacent lib/ directory. The same jars are published to Maven Central for dependency resolution, but running one on its own fails with NoClassDefFoundError. Unpack the zip and run from inside it:

% unzip tika-app-4.0.0.zip -d tika-app-4.0.0
% cd tika-app-4.0.0
% java -jar tika-app-4.0.0.jar --help

Tika 4.x requires Java 17 or later. Upgrading from 3.x? Start with the migration guides, and see the 4.0.0 changes page for the full list of breaking changes.

See the CHANGES-4.0.0.txt file for more information on the list of changes in this release.

The following optional tika-pipes plugins may be unpacked into the plugins directory of the tika-app or tika-server distributions to add fetchers, emitters and iterators for external systems:

3.x Maintenance Line: 3.3.2

Tika 3.3.2 is the current release of the 3.x line, which remains supported. It runs on Java 11 or later and ships the traditional runnable jars rather than zip distributions. New work goes into 4.x; the 3.x line receives bug fixes and dependency upgrades.

See the CHANGES-3.3.2.txt file for more information on the list of changes in this release. Documentation for 3.x lives at tika.apache.org/3.3.2.

The U.S. Government Department of Commerce, Bureau of Industry and Security (BIS), has classified this software as Export Commodity Control Number (ECCN) 5D002.C.1, which includes information security software using or performing cryptographic functions with asymmetric algorithms. The form and manner of this Apache Software Foundation distribution makes it eligible for export under the License Exception ENC Technology Software Unrestricted (TSU) exception (see the BIS Export Administration Regulations, Section 740.13) for both object code and source code.
