ant build for chapter 3

I’m very new to java and I’m not sure why I’m getting this error when trying to use ant in the code example. This is on page 47. I believe I have everything setup correctly but it is throwing this stack trace. I’m using jruby 1.6.5.1, Sun java version 1.6.0_26, ant 1.8.1, and ubuntu 11.04 64 bit. Any help would be greatly appreciated.

Thanks,

Dan

Hi, Daniel.

Sorry about this. I’m not sure why javac is crashing; I’ve written to Nick and Tom to see if they’ve seen this error before.

Daniel,

Right after you see this error, what do you get for the output of the following commands:

- ant -version
- java -version
- jruby -version

I know you said you have all the versions installed and those seem to be correct, I just want to verify that those are the versions that are being used when you go to build and run the code.

/Nick

Here my output. I upgraded my development machine the latest release of ubuntu, rvm, & jruby. ant and java where installed through apt-get.

∴ ant -version
Apache Ant™ version 1.8.2 compiled on August 19 2011

∴ java -version
