Subject Re: Ant not respecting JAVA_HOME

Brian,

How are you opening command prompt? From start->run by typing 'command' or 
by typing 'cmd'?

Thanks,

Re: Ant not respecting JAVA_HOME



Thanks a lot for the help guys.  Definitely making improvements.  The
Progra~1 shorthand works to get Ant to find the right JDK when setting the
JAVA_HOME manually before running the build... without having to manually
set ANT_HOME, etc (commands below).  So I guess that is just something I
will need to do manually each time before I run a build?  Something was 
said
about a .bat file, I guess I could I write a bat file to automate 
resetting
JAVA_HOME each time, couldn't I?

This is the output from the Windows command prompt when I use the Progra~1
shorthand:

C:\Users\Brian>cd C:\AntTest
C:\AntTest>set JAVA_HOME=C:\Progra~1\Java\jdk1.6.0_23
C:\AntTest>Ant
Buildfile: C:\AntTest\build.xml

hello:
     [echo] Hello, World

BUILD SUCCESSFUL
Total time: 0 seconds

Looks good!  I wrote a little .bat file (my first one, hence the 
ignorance),
but it closes and opens before I can see the output to confirm there are 
no
errors.  This is what it looks like:

pause
cd C:\AntTest
set JAVA_HOME=C:\Progra~1\Java\jdk1.6.0_23
Ant
pause

I does run the target, but for some reason, the first pause works, but the
last pause doesn't work and the command prompt closes before I can read 
the
output.  I guess what I'm envisioning is a .bat which would:

   1. set the JAVA_HOME
   2. prompt me for the Ant target I want to run
   3. run the ant target

Thanks again for a few tips for this Ant rookie,
Brian
