How to change locale while calling WidgetsetCompiler from eclipse plugin?

i’am a Vaadin newbie, and got a problem. I googled it for 3 hours and couldn’t found and working answer :frowning:

I tried to call widgetset compiler from eclipse plugin to try official vaadin dashboard demo app.
but i got:
“java.lang.IllegalArgumentException: No enum constantİVE”

here, you can see the wrong letter, “NATİVE” should be “NATIVE”
This is a locale problem. I changed computer’s locale, eclipse locale, jre locale … etc…

I thought, if i could change the compiler’s locale, the problem will pass.
I saw a console log i printed below.

How can i change the widgetset compiler’s locale ?

Thank you for your interest…
