[Rajeev Ravindran]

shld i have to creat a build.xml file for running ant ??
i have downloaded the zip file of ant from apache . when i tried
d:\ant>Ant
Buildfile: build.xml does not exist!
Build failed
later i created a build.xml file its like

 
<?xml version="1.0"?>

hi all,
i didnt get any reply from ranchers . I still couldnt find the cause of VerifyError..But when I tried to build the same using Win 98 it worked..First it was showing some errors regardign the syntax of my build.xml file, i cleared it and it worked..I still wonder wat is wrong with my Win NT Professional..
Thanks
Raj

I had a similar problem an found two ways to fix it:
1.- Change jdk version. Apparently some code you are using needs a different jdk. In my case if I used jdk 1.3.1_01 it worked fine. If I used 1.3.1_10 it didn't.
2.- use the -noverify when invoking java

Hi there,

Can anyone help me with this as I am new to Ant build.
I am getting the java.lang.VerifyError when I try to run my build with a target environment.

BUILD FAILED

java.lang.VerifyError: (class: org/apache/tools/ant/taskdefs/optional/Native2Ascii, method: createMapper signature: ()Lorg/apache/tools/ant/types/Mapper;) Incompatible type for getting or setting field

I looked at a similar question earlier, and tried changing the JDK to a version 1.3.1_10, it did not work. The build.xml is as follows -
