The Hudson system is used to build the nightly snapshots of the Taverna 2.x source code.
The latest successful build can be accessed on-line. Select the *-bin.zip file, download it and then unzip it. You will then be able to run the snapshot using run.sh or run.bat.
If you are using a Mac, remember to set the dot location.
We are not doing nightly builds of Taverna 1.7.x. You can still download the latest 1.7.x release.
