[news.eclipse.tools.jdt] Re: ant build files not working in M7 - works f

["Michael Moser" <mmo@xxxxxxxxxxxxxx>]

I just ran into the same and was able to fix it:

It appears that eclipse had copied over the preferences from my previous 
workspace (I switched directly from 3.0.2 to 3.1M7) and did not adapt 
certain pathes:

In Preferences => Ant => Runtime => Classpath tab I had to redefine the 
Ant-Home to now point to "C:\eclipse\plugins\org.apache.ant_1.6.3" in my 
case. it was still pointing to "C:\eclipse\plugins\org.apache.ant_1.6.2" 
which was the location in 3.0.2, but which had disappeared with my 
switch to 3.1M7. Maybe it's possible to use some classpath variable 
here, to make this adaptation automagically, but this solved my problem 
for now...

Hope that helps...
Michael
