Suddenly ALL jobs began to fail on MsBuild step.

I tried to upgrade/downgrade MsBuild plugin, restart Hudson, restart machine. Nothing helped.

Have you set the location of MSBuild for the node?

Here are screenshots of MsBuild configuration from "Configure System" and "Configure Job" screens.

The problem has just solved as suddenly as it started. The only thing I did was removing Git settings from "Configure System" screen. After that all jobs began to run MsBuild. Any ideas what was this about? Smile

I ran into the same error after upgrading to Hudson 3.3.0 and ended up changing from backslashes (\) to forward slashes (/) to resolve the issue.

Was:
C:\Windows\Microsoft.NET\Framework\v3.5\msbuild.exe

Changed to:
C:/Windows/Microsoft.NET/Framework/v3.5/msbuild.exe

After some experiments I can generalize the problem and the workaround.

Problem: After Hudson restart, all jobs begin to fail on MsBuild step (NullPointerException).
Workaround: After restart, change anything in "Configure System" UI (you can actually change something and then change it back),

This is definitely a bug of version 3.3.0. Reported https://bugs.eclipse.org/bugs/show_bug.cgi?id=477198
