Annoying string substitution validated when used as vm argument i run configuration [message #1731668]

Hi,

We have used Luna for a long time but wanted to check if we could use Mars edition.
Everything looked fine until we found out that we have to add all string substitution variables.

Example:

In our run configuration of our test suite we have the following vm argument:

-Ddata=${var1}

Then I press "Run" button.

Launching confiuration .... encountered a problem.

Reference to undefined variable 'var1'

What is the purpose of this validation? Is it not possible to turnoff this validation?
Our users of Eclipse thinks it is very confusing and we get a lot of questions about this. Any workarounds?

All input appreciated.

Mikael,

It sounds like this question:

Hi,

Yes it seems to be the issue so I we use:

-Ddata=$"{var1}"

It will not try to validate.

Do you know what is the purpose of this and which version of Eclipse it was introduced in?

Mikael,

I thought string substitutions have always been there. The point is
that you can use Window -> Preferences -> Run/Debug -> String
Substitutions to define what to substitute so that the run
configurations can be parameterized to suit different user
configurations, e.g, locations of things that might be different on each
machine.
