ant build.xml file doesn't exist

After the installation o开发者_如何学JAVAf my ant in my windows 7 . In cmd i typed ant -v it's given the ant version but it says the following also.

Buildfile: build.xml does not exist!
Build failed

What's the problem in the system. How i can rectify this issue?

You should use ant -version command instead.
The -v option is equivalent of -verbose option.
See Command-line Options Summary

---

If I understand correctly, you assumed that -v is the "print version" command. Check the documentation, that is not the case -- instead ant -v is running ant build in verbose mode. So ant is trying to perform your build, based on the build.xml file, which is obviously not there.

To answer your question explicitly: there is probably nothing wrong with both the system nor ant installation.

---

may be you can specify where the buildfile is located and then invoke desired action.

Eg: ant -file {BuildfileLocation/build.xml} -v

---

You have invoked Ant with the verbose (-v) mode but the default buildfile build.xml does not exist. Nor have you specified any other buildfile for it to use.

I would say your Ant installation is fine.

---

If you couldn't find the build.xml file in your project then you have to build it to be able to debug it and get your .apk

you can use this command-line to build:

android update project -p "project full path"

where "Project full path" -- Give your full path of your project location

after this you will find the build.xml then you can debug it.

---

this one works in ubuntu This command will cre android update project -p "project full path"

---

There may be two situations.

1. No build.xml is present in the current directory
2. Your ant configuration file has diffrent name.

Please see and confim the same. In the case one you have to find where your build file is located and in the case 2, You will have to run command ant -f <your build file name>.

---

I have still this issue i have my build.xml file inside the sample folder .

---

Please install at ubuntu openjdk-7-jdk

sudo apt-get install openjdk-7-jdk

on Windows try find find openjdk

---

Using ant debug after building build.xml file :

in your cmd your root should be your project at first then use the ant debug command e.g:

c:\testApp>ant debug
