How to run ANT script from .BAT/.CMD?

Imagine you need to call ANT script from BAT/CMD file.
Ant script:


 
  
 


And here is BAT file:

@echo off
echo BAT - Before Ant run
ant -f build.xml
echo BAT - After Ant run

Unfortunately, when you run this BAT you get the next output:
BAT - Before Ant run
Buildfile: D:\Projects\blog\build.xml

bat-test:
     [echo] Message from ANT

BUILD SUCCESSFUL
Total time: 0 seconds

So, where is the "BAT - After Ant run" echo message?

The problem is that Ant on Windows executed via ant.bat file and based on this we're calling one BAT file from another. We have to use CALL command to solve this issues, here is official note from CALL help:
Calls one batch program from another.
CALL [drive:][path]filename [batch-parameters]
batch-parameters   Specifies any command-line information required by the batch program. 
And, here is the update BAT file:

@echo off
echo BAT - Before Ant run
call ant -f build.xml
echo BAT - After Ant run
