Eclipse includes a JavaScript facility.

Version of Eclipse

As of February 2016, I was able to install the JavaScript Development Tools, which allowed me to view .js files

However, the Problems window showed errors with the org/terraswarm/accessor/accessors/web/vendors directory that I was not able to exclude.

To install the JavaScript Development Tools:

  1. Click on Help -> Install New Software
  2. In the the Install Window
    1. Find the "Work With" entry and chose Mars -
    2. Search for JavaScript and select JavaScript Development Tools
    3. Click through the dialogs.

Ptolemy II

To set up Ptolemy II, see

Note that if you are using TerraSwarm Accessors, you will need read access to the TerraSwarm accessor svn repo (available only to members of TerraSwarm universities and companies). In addition, you probably want to run cd $PTII; ./configure to set up the Eclipse .classpath file.

In Eclipse, use Window -> Open Perspective -> JavaScript to edit JavaScript files.

Excluding JavaScript Directories

Eclipse will warn about JavaScript problems in JavaScript files that are provided by third party libraries.

It turns out that JavaScript has a separate build path!


  1. In the Project Explorer, right click on the project, select Properties
  2. In the properties window, select JavaScript->Editor->Include Path
  3. Select the Source path
  4. Select Exclude and add directories

Unfortunately, these are saved in $PTII/.settings/.jsdtscope instead of .classpath

.jsdtscope looks like:

<?xml version="1.0" encoding="UTF-8"?>
        <classpathentry excluding="**/apps/|**/codeDoc/|**/jsdoc/|**/vendors/|RobotChase/|adm/|pt\
kind="src" path=""/>
        <classpathentry kind="con" path="org.eclipse.wst.jsdt.launching.JRE_CONTAINER"/>
        <classpathentry kind="output" path=""/>
