How to specify Build Path / Classpath variable

[vdeschenes]

Hi,

I am trying to build a workspace using HeadlessEclipse.
I have some Flex projects which use a variable configured using the
Eclispe UI under help/preference/Build Path/Classpath variable.

When building headless the value set using the UI is not found.

Related logs:
ERROR: 'VARIABLE_NAME\path\' is not a valid location. The location is
relative to undefined workspace path variable 'VARIABLE_NAME'.


Any solution ?
Is there a way to provide these variable to eclispec or to
HeadlessEclipse in the command line ?
Why is the variable honored when using the UI and not when using the
command line ?

Thanks.
