Welcome to Apache Tika https://tika.apache.org/

license Jenkins Jenkins tests Maven Central

Apache Tika(TM) is a toolkit for detecting and extracting metadata and structured text content from various documents using existing parser libraries.

Tika is a project of the Apache Software Foundation.

Apache Tika, Tika, Apache, the Apache feather logo, and the Apache Tika project logo are trademarks of The Apache Software Foundation.

Getting Started

Pre-built binaries of Apache Tika standalone applications are available from https://tika.apache.org/download.html . Pre-built binaries of all the Tika jars can be fetched from Maven Central or your favourite Maven mirror.

Tika 1.X is scheduled for End of Life (EOL) on September 30, 2022. We will continue to make security improvements until the EOL, but we do not plan to back port new functionality from the main/2.x branch. See Migrating to 2.x below for more details.

Tika is based on Java 8 and uses the Maven 3 build system. N.B. Docker is required in the main/2.x branch to complete all unit tests. You can pass the -DskipTests flag if you wish to skip tests.

To build Tika from source, use the following command in the main directory:

mvn clean install

The build consists of a number of components, including a standalone runnable jar that you can use to try out Tika features. You can run it like this:

java -jar tika-app/target/tika-app-*.jar --help

To build a specific project (for example, tika-server-standard):

mvn clean install -am -pl :tika-server-standard

If the ossindex-maven-plugin is causing the build to fail because a dependency has now been discovered to have a vulnerability:

mvn clean install -Dossindex.skip

Maven Dependencies

Apache Tika provides Bill of Material (BOM) artifact to align Tika module versions and simplify version management.

If you use Apache Maven:

<project>
  <dependencyManagement>
    <dependencies>
      <dependency>
       <groupId>org.apache.tika</groupId>
       <artifactId>tika-bom</artifactId>
       <version>2.x.y</version>
       <type>pom</type>
       <scope>import</scope>
      </dependency>
    </dependencies>
  </dependencyManagement>

  <dependencies>
    <dependency>
      <groupId>org.apache.tika</groupId>
      <artifactId>tika-parsers-standard-package</artifactId>
      <!-- version not required since BOM included -->
    </dependency>
  </dependencies>
</project>

For Gradle:

dependencies {
  implementation(platform("org.apache.tika:tika-bom:2.x.y"))

  // version not required since bom (platform in Gradle terms)
  implementation("org.apache.tika:tika-parsers-standard-package")
}

Migrating to 2.x

The initial 2.x release notes are available in the archives.

See our wiki for the latest.

Building from a Specific Tag

Let's assume that you want to build the 1.22 tag:

0. Download and install hub.github.com
1. git clone https://github.com/apache/tika.git 
2. cd tika
3. git checkout 1.22
4. mvn clean install

If a new vulnerability has been discovered between the date of the tag and the date you are building the tag, you may need to build with:

4. mvn clean install -Dossindex.skip

If a local test is not working in your environment, please notify the project at dev@tika.apache.org. As an immediate workaround, you can turn off individual tests with e.g.:

4. mvn clean install -Dossindex.skip -Dtest=\!UnpackerResourceTest#testPDFImages
