According to the ANT documentation (http://jakarta.apache.org/ant/manual/using.html#targets) a target can be named with a starting hyphen if the target should not be called directly. I think that these targets should be excluded from the target list in the "Run Ant" dialog.
Moving to Platform UI.
Targets names which start with "-" are not shown in the new external tool rework ui. Note: new external tool work is not yet released to the head stream and won't for a while yet.
