I have a script that builds a lot of projects. Some of them are NetBeans Ant-based projects, many are custom things that launch Visual Studio to build a VS solution file. When I run my build from my root folder so all of the projects build (these are NOT gradle sub-projects, the subfolders are scanned manually by the build script and builds are fired off via GradleLauncher.newInstance)
Ultimately what fails (after several projects that succeed) is an ant build using Gradle’s built-in Ant support… log shows this: … Task ‘:-do-jar-with-libraries-create-manifest’ has not declared any outputs, assuming that it is out-of-date.
FAILURE: Build failed with an exception.

Where: Script ‘C:\Users\scott.palmer\dev\KayakSDK\BuildScripts\Defaults.gradle’ line: 757

What went wrong: Execution failed for task ‘:-do-jar-with-libraries-create-manifest’. > Could not create C:\PathToMyProject\SomeJavaProject\build\null1120807625

Try: Run with --stacktrace option to get the stack trace. Run with --debug option to get more log output.
BUILD FAILED

If I re-run the build for that project it succeeds. It’s the strange path that it is trying to create in the build folder that I don’t understand: “null1120807625”
The numbers may change, but it always fails this way… but not always on the same project. I’m running Gradle 1.0-rc3
