Get WARN when start alfresco

[baallee]

i use source code that check out from svn, to run in eclipse.
and i got followwing warn message:
16:32:44,406 Userystem WARN  [web.scripts.DeclarativeRegistry] Unable to register script classpath:alfresco/webscripts/org/alfresco/indexfamily.get.desc.xml due to error: Failed to read Web Script description document classpath:alfresco/webscriptsorg/alfresco/indexfamily.get.desc.xml ; Document org/alfresco/indexfamily.get.desc.xml does not exist within store classpath:alfresco/webscripts

i found code in ClassPathStore.java

 public void setClassPath(String classPath)
    {
        String cleanClassPath = (classPath.endsWith("/")) ? classPath.substring(0, classPath.length() -1) : classPath;
        this.classPath = cleanClassPath;
    }‍‍‍‍‍

i want know why need cutout last char '/'? and how to fix this warn?
thanks!

Web Script descriptors (the loading of which is causing the warning you're seeing) are files not folders, hence the need to clean any trailing '/' characters prior to loading the file.
