Hello Ant users,
I upgraded from Ant version 1.7.1 to version 1.8.0 and noticed that the
performance of my build dropped dramatically. I tracked down the
performance loss to an area of my build script where I operate heavily
with the Ant-Contrib "For" and "Variable" tasks on a path-like structure.
In effect I loop over the contents of a fileset and append a string for
each element to a property, which is updated via the "Variable" task. I
noticed that, the bigger the fileset is, the greater is the performance
loss (9 seconds with Ant 1.7.1 versus 3 Minutes with Ant 1.8.0 for a big
fileset!). As it runs fast with Ant 1.7.1, and I did not change my version
of Ant-Contrib, I assume that something has changed inside Ant which
causes this.
Has anyone noticed related problems with Ant 1.8.0? Any idea?
Regards,
Christoph
