[armedbear-devel] Can't build rev14574 with ant 1.8.2

[Dmitry Nadezhin]

1) I check out a fresh working copy from SVN trunk (rev14574).

2) Then I try to build. It fails.
<<<<<<<<<<<<<<
$ ant
Buildfile: MYWORKDIR/build.xml

abcl.clean.maybe:
     [echo] Cleaning all intermediate compilation artifacts.
     [echo] Setting 'abcl.build.incremental' enables incremental compilation.

abcl.clean:

abcl.copy.lisp:

BUILD FAILED
MYWORKDIR/build.xml:200: file attribute is null!

Total time: 0 seconds
>>>>>>>>>>>>>>>>>

3) Then I comment line 200 in build xml. This line was:
 	<file name="${basedir}/abcl.rdf"/>

4) and run again
$ ant
Now the build passes ok.

Ant version is:
$ ant -version
Apache Ant(TM) version 1.8.2 compiled on December 20 2010

The documentation says that ant-1.7.1 is enough.

I have the workaround. Nevertheless, how to build properly ?
