Latest posts

In this article we are happy to introduce new features and improvements that have been implemented as part of the JSDT project and now available in the Neon.1 release:

  • Oomph installer for JSDT setup

  • Node.js debugger improvements

  • New JavaScript debugger

  • "Quick Access" for Gulp / Grunt tasks

  • npm scripts support

Overall, 41 bugzillas have been resolved during the Neon.1 development cycle (some of the bugs have been waiting to be fixed for more than 5 years!) Also, we would like to shed some light on our plans for the Neon.2 release.

In order to have all new JavaScript features available out-of-the-box, please, use "Eclipse IDE for JavaScript and Web Developers" / "Eclipse IDE for Java EE Developers" packages

Oomph installer for JSDT setup

Want to contribute to JSDT project but do not know how? Think that environment setup is too difficult and comprehensive? Now you can easily setup JSDT using Oomph within a few minutes! Here is a short demo video which explains how to do it:

More details about Oomph setup can be found on the following link

Node.js Debugger Improvements

Node.js support was originally implemented as part of the Eclipse Neon release. In Neon.1 debugger facilities have been significantly improved. Previously in order to change the code during the debug session one should have saved the JavaScript file, right click on it → V8 Debugging → Push Source Changes to VM. Now saving the file is just enough - new changes will be applied automatically:

node debugger hot swap

Also, there are a few important bug fixes that improve the debugging experience:

  • Bug 491735 - Terminating V8 debugger process should also kill main Node process

  • Bug 497685 - Cannot set a breakpoint in "node_modules" (Windows specific)

  • Bug 497424 - Source not found for main .js file inside node_modules

More details about Node.js support in Eclipse can be found in the article Neon and Node.js: A magical friendship!

New JavaScript Debugger

Now there is a possibility to debug JavaScript using Chrome / Chromium browser. Basically, in order to debug JavaScript one should simply right click on the html file → Debug As.. → Chrome / Chromium Debugger:

There is also a possibility of debugging JavaScript for applications running on servers using Chrome / Chromium Debugger menu item:

"Chrome / Chromium debugger" menu enabled on the server adapters will work only for maven projects in which JavaScript files are located in the "webapp" folder. However, one can always tune the source mapping logic for particular project manually and run Chrome / Chromium with the debugging port enabled. More details about manual debugger setup can be found in the following video

"Quick Access" for Grunt / Gulp tasks

Now it is possible to execute tasks via "Quick Access" - just press Cntrl + 3 / ⌘ + 3 and choose Run As Grunt / Gulp task:

gulp task quick access

npm scripts support

All npm scripts defined in the package.json can be now executed via Run As.. → npm Script context menu:

npm scripts

The output of the script command will be reflected in the "Console" view:

npm scripts console

Neon.2 Agenda

In the next release we are going to switch to the Closure compiler which is more tolerant and has better performance in comparison with currently used Esprima parser. Moreover, we are going to return broken JavaScript search facilities back to JSDT. Actually, most of the work in the search direction is already done:

Other plans are coupled with polishing Node.js / JavaScript debuggers and making the whole feature set smooth, stable and complete. If you want to have some particular bug fixed in Neon.2, please, speak up on the wtp-dev mailing list or let us know on twitter, youtube, stackoverflow etc.

Thank you!

Thank you to the contributors who made the Neon.1 release happen:

  • Patrik Suzzi

  • Esteban Dugueperoux

  • Victor Rubezhny, Red Hat

  • Gorkem Ercan, RedHat

  • Angel Misevski, RedHat

  • Shane Bryzak, RedHat

We would like to express special gratitude to the community for their feedback! We look forward to hearing your comments, remarks and proposals about new Neon.1 release.
Have fun!

Happy to announce 4.4.2.AM1 (Developer Milestone 1) build for Eclipse Neon.

Downloads available at JBoss Tools 4.4.2 AM1.

What is New?

Full info is at this page. Some highlights are below.

OpenShift 3

Although our main focus is bug fixes, we continue to work on providing better experience for container based development in JBoss Tools and Developer Studio. Let’s go through a few interesting updates here and you can find more details on the What’s New page.

Cluster common namespace

When looking for Openshift resources (builder images, templates), a common namespace is browsed. Earlier hardcoded openshift namespace is now configurable with default value openshift.

Please note that templates are still loaded from the òpenshift namespace and not the from configured common namespace, this will be fixed for the next release.

It can be accessed and modified through the connection extended properties:

CDK server using native terminal for better user interactions

The CDK server adapter now uses a native terminal that allows better interaction with the user. In the case credentials are not passed in the Vagrant environment, the user will be asked just as with the standard Vagrant CLI and in case of registration failures, retries will be performed.

First, make sure your CDK server adapter is configured not to pass credentials:

CDK editor

Then, start the CDK server adapter and a new terminal window will open, asking for registration:


If you answered y to the previous questions, then the terminal window will ask for username:


Then the terminal window will ask for password:


If the registration fails, then the terminal window will perform retries and ask again for username and password:
