Im trying to build spark on windows, I've been following this guide
Problem is I got to the command line and run "ant release" in the build directory and the last thing I get it:
C:\spark_dev\spark_2_5_8\build\build.xml:276: Problem: failed to create task
Cause: The name is undefined.
Action: Check the spelling.
Action: Check that any custom tasks/types have been declared.
Action: Check that any <presetdef>/<macrodef> declarations have taken place.
Cant seem to get past this, tried on older builds too (5.7, 5.6) Also this is the unchanged code from the repository, I havent made any changes yet.
Anyone know how I can fix this?
