Gradle can't copy png file in java project

问题

so I've added a png img to my resources, since I want to use it in my project.  
But Gradle seems not to let me build the project anymore, it's giving me the following error:  

    * What went wrong:
    Execution failed for task ':processResources'.
    > Could not copy file 'C:\workspace\Java\Utilities\EmailService\src\main\resources\img\watermark.png' to 'C:\workspace\Java\Utilities\EmailService\build\resources\main\img\watermark.png'.

Important part of Stacktrace is:  

    Caused by: groovy.lang.GroovyRuntimeException: Failed to parse template script (your template may contain an error or be trying to use expressions not currently supported): startup failed:
    SimpleTemplateScript28.groovy: 4: illegal string body character after dollar sign;
       solution: either escape a literal dollar sign "$5" or bracket the value expression "${5}" @ line 4, column 99.

**得分**: 1
我认为是你的 `processResources` 配置中的 `filter` 语句。你正在要求 Gradle 替换 PNG 内的文本，但它无法理解 PNG 中的文本（这是因为它内部没有文本；可能不符合任何合理的字符编码）。

I think it&#39;s the `filter` statement in your `processResources` config. You&#39;re asking Gradle to replace text inside the PNG, but it can&#39;t make sense of the text in the PNG (which is because there is no text in it; probably doesn&#39;t conform to any reasonable character encoding).
