How to use ant build

[baalexander]

I have a fresh instance of Ubuntu 12.04.

What I've done so far:

1. sudo apt-get install ant
2. cd utils
3. ant build.xml

I then get the following error:

Unable to locate tools.jar. Expected to find it in /usr/lib/jvm/java-6-openjdk-amd64/lib/tools.jar
Buildfile: /home/vagrant/ws/roslibjs/utils/build.xml

BUILD FAILED
Target "build.xml" does not exist in the project "roslibjs". 

Total time: 0 seconds

Any ideas?

cd utils
ant

you also need sudo apt-get install yui-compressor jsdoc-toolkit

The sudo apt-get install yui-compressor jsdoc-toolkit fixed it.

For others, the steps were:

1. sudo apt-get install ant yui-compressor jsdoc-toolkit
2. cd utils
3. ant

And if ant fails the first time on minimization, just run it again
