Subject Re: ${ant.home} partly broken in Ant 1.6.2 - also ${ant.library.dir}
Date Tue, 04 Jan 2005 16:35:59 GMT
Hello Antoine,

I'm not sure why you say that this is an integration problem.  The position
of 'ant.home' within Eclipse should always be within the
eclipse\plugins\org.apache.ant_1.6.2 directory as mine is: whether I have
Eclipse in C:\Program Files as you do or E:\eclipse\3.0.1\eclipse as I do,
doesn't seem like it should make a difference.

However, I will mention this on an appropriate Eclipse forum to see their
opinion while I await others on the Ant mailing list to express their
opinions.
