The plugin includes:

    ctrl + space
  • Code completion for Camel property placeholders (cursor after
  • Real time validation for Camel endpoints in Java, XML (underline errors in red)
  • Real time validation for Camel simple language in Java, XML (underline errors in red)
  • Endpoint options filtered to only include applicable options when used as consumer vs producer only mode
  • Quick navigation to other Camel routes routing to this route by clicking the Camel icon in the gutter
  • Intention to add new Camel endpoint (

    in empty string)
  • Quick documentation for Camel endpoints and external link to Camel component opening in web browser (
    ctrl + j
  • Show endpoint information in tooltip when hovering mouse over from/to etc in Java route builders
  • Supports 3rd party Camel components (if they have been properly built with Camel JSon schema metadata)
  • Attempts to use same version as camel-core dependency from the loaded project (requires Camel 2.16.1 or newer and may require download over internet)
  • Inspection (analyze code) to validate Camel endpoints in Java, XML
  • Camel icon in gutter can be customized by choosing one of the three provided icons
  • Supports loading camel-catalog from third party Maven repositories define in the project Maven pom.xml file
  • Supports Maven, Gradle, and SBT based projects

When the plugin becomes more complete and stable then the intention is to donate the source code to Apache Software Foundation to be included out of the box at Apache Camel.

However currently the code is located at github to allow faster and wider collaboration in the community.


How to install

The plugin

Apache Camel IDEA plugin
is available from Jetbrains Plugin Repository at:

You should be able to install the plugin from within IDEA plugin manager. Open the

menu and select
. Click the
Browse repositories...
Apache Camel IDEA plugin
is not available in the plugin list. From there you should be able to browse all the plugins from the Jetbrains remote plugin repository.

How to try

Currently the plugin is editing Java endpoints in Java source code.

You can open any Camel example which uses Java code, such as

an select the
route class and position the cursor on any of the Camel endpoints after the '?' mark and press
ctrl + space

Currently its only endpoint options in the URI query section which can be edited. Its planned to add support for editing the options in the URI context-path section as well.

IDEA Compatibility

The Camel IDEA plugin currently requires IDEA 2016.2 or newer. If you are using a older version of IDEA and still want to try the plugin, follow the guide here

IDEA provides more information about their SDK versions here:

Building from source

You can build the plugin from source code, which requires to setup IDEA for plugin development.

You can follow the guide from Jetbrains here:

To be able to browse the IDEA SDK source code you can clone the IDEA community source code, as described in the guide above. I did this so I can peak inside their source code, because you need this to find out how to hook into various IDEA APIs which is massive and takes longer time to figure out to use. Sadly Jetbrains are not very good at documenting their APIs with neither javadoc, or documentation to their own plugins. However with some trial and run you can find out bit by bit.

Importing project as gradle project

Importing the project into IntelliJ as plug-in only require you choose ìmport from external model` and select gradle

Important : if you are using the Ultimate version you can set a gradle property in your

  • Open your IDEA

After completing all steps and if everything is setup correctly, then you can launch the plugin by running the gradle task

and for building and running test run the gradle task

gradle task

You can also launch the plugin in debug mode where you can put breakpoints in the source code. This is very handy to debug the code and find issues. However for code changes you need to stop and start the plugin again.

Contributing / Hacking on the code

We love contributions. And anyone is welcome to join and hack on the code. For code changes you can submit github PRs (pull requests) which anyone can review and get merged into the code base.

For people who hack more on the code, can be granted commit rights.

You should be willing to provide any code changes under the ASF license and that the code later will be donated to Apache Software Foundation to be included out of the box at Apache Camel. If you are not willing to accept this, then we are sorry, but then any code contributions cannot be accepted.


Jetbrains provides a FAQ for the IDEA SDK which is massive and takes time to learn.


They also provide a forum for API Plugin Development. -
