The project has resource \*.yml files with multiline strings values which contain SimpleTemplateEngine-like placeholders `${placeholder}`. When the `processResources` task is being executed the `expand` fails because it can not do the template processing.  
Is there a way to just skip this template processing in `FilterChain` or `processResources` for certain files?

I found an answer myself:

```gradle
    processResources {
        filesMatching("**/*.yml") { matchedFile ->
            filter { line ->
                line.replace('${', '\\${')
            }
        }
    }

```

Escape the placeholders in the \*.yml to prevent Gradle’s template expanding to throw `MissingPropertyException` because these placeholders are later used from the application to parametrize dynamically.
