Question

I’m following an example from Pragmatic Project Automation. I’m running on Windows 7 and pulling the project from a local Subversion repo. When I run ant in the project’s base directory, I get the following error [junit] couldn't delete .svn. Here’s the full output of the command:

Buildfile: S:\CruiseControl\builds\dms\checkout\dms\build.xml

    [mkdir] Created dir: S:\CruiseControl\builds\dms\checkout\dms\build\test

and the build.xml file:

Why is JUnit attempting to delete a .svn directory? Which one is it even trying to delete? Why is it failing to do so?

Answer 1

It looks like test case testTitleSearch in com.pragprog.dms.SearchTest is failing. The same then happens with testContentSearch. They are perhaps trying to clean house before starting. I’m guessing you inadvertently put the test case’s scratch directory under version control when cloning it locally.
