----------------------------------------

Unfortunately I've faced the same issue with version 3.0.7.

>                 URL: https://issues.apache.org/jira/browse/GROOVY-8701
>             Project: Groovy
>          Issue Type: Bug
>          Components: Templating
>    Affects Versions: 2.5.1
>            Reporter: Szymon Stępniak
>            Priority: Minor

> Using {{groovy.text.StreamingTemplateEngine}} to render a template containing escaped character (e.g. {{\$}}) produces output containing escape character. Using the same template with {{groovy.text.GStringTemplateEngine}} does not produce an output containing escape character.
> The quickest way to reproduce the issue:
>  
> {code}
> import groovy.text.StreamingTemplateEngine
> def placeholders = [
>   "StreamingTemplateEnginePlaceholder": "SOME_VALUE",
> ]
> def templateContent = new File('test.php.template').text
> def engine = new StreamingTemplateEngine()
> def configContent = engine.createTemplate(templateContent)
>   .make(placeholders)
>   .toString()
> println configContent
> {code}
> test.php.template
> {code:php}
> <?php
> \$my_php_config_variable = "${StreamingTemplateEnginePlaceholder}"
> ?>
> {code}
> Output:
> {code:php}
> <?php
> \$my_php_config_variable = "SOME_VALUE"
> ?>
> {code}
> When template does not escape dollar character then rendering such a template produces following exception:
> {code:bash}
> Caught: groovy.text.TemplateExecutionException: Template execution error at line 2:
>          1: <?php
>      --> 2: $my_php_config_variable = "${StreamingTemplateEnginePlaceholder}"
>          3: ?>
> groovy.text.TemplateExecutionException: Template execution error at line 2:
>          1: <?php
>      --> 2: $my_php_config_variable = "${StreamingTemplateEnginePlaceholder}"
>          3: ?>
> 	at test.run(test.groovy:9)
> Caused by: groovy.lang.MissingPropertyException: No such property: my_php_config_variable for class: groovy.tmp.templates.StreamingTemplateScript1
> 	... 1 more
> {code}
