Maven coordinates

Create a new project with this extension on code.quarkus.io

Or add the coordinates to your existing project:

<dependency>
    <groupId>org.apache.camel.quarkus</groupId>

</dependency>

Check the User guide for more information about writing Camel Quarkus applications.

Usage

Parser modules

Tika parses only the formats whose parser module is on the classpath. camel-tika brings the HTML and plain text modules. For any other format, add its module to your application, e.g. for PDF:

<dependency>
    <groupId>org.apache.tika</groupId>
    <artifactId>tika-parser-pdf-module</artifactId>
</dependency>

The Camel Quarkus BOM manages the version of tika-parser-pdf-module only. For other modules, use the version of org.apache.tika:tika-core that camel-tika brings.

In native mode, the HTML, plain text and PDF modules are supported.

Character encodings in native mode

tika-parser-text-module, brought by camel-tika, registers Tika’s MojibusterEncodingDetector. It matches candidate encodings by name (windows-1252, ISO-8859-*, Shift_JIS, …) at runtime, while native images bundle only a small subset of the JDK charsets by default. To keep document parsing working, camel-quarkus-tika enables all JDK charsets (-H:+AddAllCharsets) for your native build when the detector is present.

This adds a few MB to the native executable. Because the extension requests the charsets, quarkus.native.add-all-charsets=false cannot turn them off, and there is no need to set it to true yourself.
