What is it?

The Object Teams Development Tooling is an extension to the Eclipse platform, serving as an integrated development environment (IDE). It embeds the role-based and aspect-oriented language Object Teams/Java into the IDE, providing software developers with a rich set of tools to support the development.

Read an Overview of the OTDT (2 pages, in German).

Other than that the OTDT has no specific platform requirements.

Download

Installing the OTDT

hints and background on installing/updating.

Starting with version 1.2.0 the OTDT is provided as a set of features installable from the following update site:
http://www.objectteams.org/distrib/otdt-updates-1.2

Incompatibility: Due to a necessary change in our versioning scheme, it is not possible to incrementally upgrade an OTDT ≤ 1.2.3 to a greater version, i.e., if you still have an OTDT 1.2.3 you can only upgrade by starting from a fresh install of Eclipse 3.4.2. We appologize for any inconvenience.
Upgrades from 1.2.4 to newer versions work as desired.

This is what you will find on the update site:

Name Content
category OTDT 1.2.x based on Eclipse 3.4 Category comprising all features of the OTDT
  feature Object Teams Development Tooling [recommended]
This umbrella feature includes all parts of the OTDT.
→ Select this if you want to develop OT/J programs.
  feature OT/Equinox Feature [alternative]
Installing this feature enables the Eclipse platform to host plugins written in OT/J.
→ Select this if you only want to run OT/J plug-ins but don't require development support.
This is also included in the above feature.
  feature OTDT Core Patch Feature [implicit]
This feature replaces the jdt core with a version that is able to handle OT/J.
→ No need to directly install this.
category Object Teams Contributions Category containing optional add-ons for the OTDT and/or OT/Equinox
  feature AspectAskerFeature [optional]
A small plugin asking the user to interactively confirm or deny aspect bindings and forced exports.

Note, that it is recommended to install the OTDT from an account that has write permissions in the Eclipse installation area.

If you are concerned about permissions, you might want to install the "OT/Equinox Feature" from a privileged account and let regular users add the "Object Teams Development Tooling" under their own account. → Cf. Eclipse bug 257178.

If you intend to install the OTDT into an IBM Rational SDP or other Eclipse-based product, please refer to these special instructions.

Should you encounter problems with installing or launching the OTDT, you may want to consult the wiki page on trouble shooting.

OT/J command line compiler

hints on using the command line compiler.

Place this jar file (approx. 2MB) into a location of your choice:

Notes on compatibility
The OTDT-feature replaces the Eclipse Java compiler with the OT/J compiler, which is in fact a modified version of Eclipse's Java compiler.
Find out about the compatibility to standard Java.
Suggested memory setting
In order to avoid problems with low memory, we advise you to start the OTDT (command eclipse ) with the following argument:
-vmargs -Xmx512m
This setting can also be adjusted in the file eclipse.ini (default there is 256m)

Versions

3.4
The OTDT is build on top of the 3.4 release of Eclipse ("Ganymede")
1.2.x
For the OTDT this is the x th release within the 1.2 stream.
3.4.4.v_OTDT_r128_xxxx
The adapted JDT core plug-in contained in the OTDT is tagged with a version number where the first three parts match that version of the original JDT core from which the OTDT is derived (here "3.4.4"), while the version qualifier contains a condensed form of the OTDT version (here "r128"). This ensures that the framework accepts the OT-version of the JDT core as an upgrade over the original.

See the Feature list for further information.
See the New&Noteworthy for changes between versions.
Fetch or browse the Source Code via anonymous subversion access.
