Question

I have file contents in a java string variable, which I want to convert it into a File object is that possible?

public void setCfgfile(File cfgfile)
{
    this.cfgfile = cfgfile
}

public void setCfgfile(String cfgfile)
{
    println "ok overloaded function"
    this.cfgfile = new File(getStreamFromString(cfgfile))
}
private def getStreamFromString(String str)
{
    // convert String into InputStream
    InputStream is = new ByteArrayInputStream(str.getBytes())
    is
}

Answer 1

As this is Groovy, you can simplify the other two answers with:

File writeToFile( String filename, String content ) {
  new File( filename ).with { f ->
    f.withWriter( 'UTF-8' ) { w ->
      w.write( content )
    }
    f
  }
}

Which will return a file handle to the file it just wrote content into
