I am using Eclipse 3.6.1 with PyDev 1.6.4 for developing a Google App Engine site. In my projects .pydevproject I want to set the path to the Google App Engine SDK based off an environment variable since I develop on my desktop and laptop (where the paths are slightly different) and I plan to check this file into source control and others environment may be different. In the XML below, I want to replace /home/jesse with the value read from an environment variable. For now I would be happy just using the current home directory.

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<?eclipse-pydev version="1.0"?>
<pydev_project>
  <pydev_property name="org.python.pydev.PYTHON_PROJECT_INTERPRETER">Python 2.5</pydev_property>
  <pydev_property name="org.python.pydev.PYTHON_PROJECT_VERSION">python 2.5</pydev_property>
  <pydev_variables_property name="org.python.pydev.PROJECT_VARIABLE_SUBSTITUTION">
    <key>GOOGLE_APP_ENGINE</key>
    <value>/home/jesse/projects/google_appengine</value>
  </pydev_variables_property>
  <pydev_pathproperty name="org.python.pydev.PROJECT_SOURCE_PATH">
    <path>/app_html5rest</path>
  </pydev_pathproperty>
  <pydev_pathproperty name="org.python.pydev.PROJECT_EXTERNAL_SOURCE_PATH">
    <path>${GOOGLE_APP_ENGINE}</path>
    <path>${GOOGLE_APP_ENGINE}/lib/django</path>
    <path>${GOOGLE_APP_ENGINE}/lib/webob</path>
    <path>${GOOGLE_APP_ENGINE}/lib/yaml/lib</path>
  </pydev_pathproperty>
</pydev_project>

I have tried:

  • ${HOME}
  • ${env.HOME}
  • $HOME

Google has not turned up much, any suggestions?
