Ant not working ???

Hi guys

I have 2 branches master/ and LO6.1/ under git/core and git/lo61

I followed the wiki page at

https://wiki.documentfoundation.org/Development/BuildingOnLinux#Multiple_Work_Dirs

Both branches were building last week but now master has issues with
Ant. Autogen.sh hit an issue with Ant and cannot go through.

------8<------------
checking for ant... /usr/bin/ant
checking if /usr/share/ant/bin/ant works... configure: error: Ant does
not work - Some Java projects will not build!
Error running configure at /home/tdf/git/core/autogen.sh line 289.
------8<------------

The logs shows these lines:

error output for details.

Apparently it complains on the file "Sem título 1.ods" that has accented
characters. Nothing changed, AFAIK, WRT locales (pt-BR) in the build.

OTOH, autogen.sh runs smoothly on the LO 6.1  branch, and Ant is happy.

Any help is welcome on how to fix this. I badly need my master build back.

Thank you in advance.
