I noticed that we have many incorrect examples of how to use Groovy string interpolation on the Pipeline Examples page.

To prevent spreading this common mistake, it would be better to correct it.

See this documentation for more context.

${flavor} isn't an environment variable (BRANCH_NAME is) so this won't work. Use withEnv.

Kind of, but not really? The result is the same, assuming you use a shell that supports it, but this won't demonstrate the pwd() Pipeline feature. The phrasing seems off for the case where we just use a shell built-in feature.

(Granted, both the existing Pipeline and this one are really artificial, neither $PWD nor pwd() are actually needed.)

Did you test this?

Even if it works, I'm unsure whether we should do it like this, as it doesn't provide an example of safe Pipeline authoring. There's still the double quote.

Perhaps something like

"""
def msbuild = tool 'MSBuild'
bat msbuild + " SolutionName.sln /p:Configuration=Release /p:Platform="Any CPU" /p:ProductVersion=1.0.0.%BUILD_NUMBER%"

Granted, this theoretically still has the problem described in https://plugins.jenkins.io/safe-batch-environment-filter/ but we know that %BUILD_NUMBER% is numeric. Perhaps mention it and move on?
