java - Issue with unrecognized option in ANT -

i have used quite bit of resources seek understand why gettting next error when attempting run ant command line:

unrecognized option: -dant.home=c:\ant\1.7.0 not create java virtual machine. error: file either empty or not contain valid choices.

to give little insight, have path include %java_home% , %ant_home%\bin. 1 of things cannot run administrator update scheme variables, user variables. has run before? give thanks help!

edit: update, uncommented @echo off @ top of ant.bat , ran ant.bat show unrecognized alternative occured below:

c:\ant\1.7.0\bin>if not "" == "" goto runantwithjikes c:\ant\1.7.0\bin>if "no" == "no" goto runantnoclasspath c:\ant\1.7.0\bin>"c:\java\jdk1.6.0_03\bin\java.exe" -classpath "c:\ant\1.7.0\li b\ant-launcher.jar" "-dant.home=c:\ant\1.7.0" org.apache.tools.ant.launch.launch er unrecognized option: -dant.home=c:\ant\1.7.0 not create java virtual machine.

update: think after doing more research, has relate classpath variable trying resolve launcher.jar file. if has encountered in windows awesome if had thought of next do. also, not using custom ant library.

update: decided include little debugging page. okay, echo out rest of batch file after line 130:

i read on manual apache should not alter class path, left alone.

the -d switch turns on debugging (it synonym -debug).

it looks wanted -d switch, defines value property i.e.,

-dant.home=c:\ant\1.7.0

you can see command line options typing:

ant -help
