I'm trying to mirror Babel update site including only a subset of languages.
Since Tycho 0.17.0, there is a great features that seems to allow to do it quite easily.
For instance for filtering on German Babel translations, I tried to use:
<_expression_>id ~= $0</_expression_>
unfortunately, it complains that I can't use ~= with Two Strings.
org.eclipse.tycho.extras:tycho-p2-extras-plugin:0.17.0:mirror failed: Cannot match a java.lang.String with a java.lang.String
Effectively, I want to use ~= Operator with a String and a SimplePattern. How can I specify to use a SimplePattern with Tycho?
