This is a known issue.

The JSON transformer in SlowCheetah v3.1.66 doesn't support the source or transform files being read-only yet.

See the following issues:
https://github.com/Microsoft/slow-cheetah/issues/86
https://github.com/Microsoft/json-document-transforms/issues/16

The merged PR#17 has a fix for Microsoft.VisualStudio.Jdt, but it hasn't been released yet.

Here are a few work arounds:

  1. Make all files writeable when checking out of source control.
  2. Call the Attrib MSBuild task before the transformation to remove the read-only file attribute.

For example:

<Attrib Files="D:\Data\…\Settings.Release.json" Normal="true"/>

  1. Call the Exec MSBuild task before the transformation to remove the read-only file attribute.

For example:

<Exec Command="attrib -R &quot;D:\Data\…\Settings.Release.json&quot;"/>
