The merge PDF function 

RegisterGroovy( "MergePDF( files ; output )" ; "import java.io.FileOutputStream;¶
import java.util.ArrayList;¶
import java.util.List;¶
¶
import com.itextpdf.text.Document;¶
import com.itextpdf.text.pdf.PdfReader;¶
import com.itextpdf.text.pdf.PdfCopy;¶
import com.itextpdf.text.pdf.PdfImportedPage;¶
¶
try {¶
  String[] inFiles = files.split(\"\n\");¶
  int f = 0;¶
  int pageOffset = 0;¶
  String outFile = output;¶
  Document document = null;¶
  PdfCopy  writer = null;¶
¶
  while (f < inFiles.length) {¶
    // Create a reader for the next document¶
    PdfReader reader = new PdfReader(inFiles[f]);¶
    reader.consolidateNamedDestinations();¶
¶
    // Retrieve the total number of pages¶
    int n = reader.getNumberOfPages();¶
¶
    pageOffset += n;¶
¶
    // Create the master document¶
    if (f == 0) {¶
	  // step 1: Create the document-object¶
	  document = new Document(reader.getPageSizeWithRotation(1));¶
	  // step 2: Create the writer that listens to the document¶
	  writer = new PdfCopy(document, new FileOutputStream(outFile));¶
	  // step 3: Open the document¶
	  document.open();¶
    }¶
    // step 4: Add content¶
    PdfImportedPage page;¶
    for (int i = 0; i < n; ) {¶
	  ++i;¶
	  page = writer.getImportedPage(reader, i);¶
	  writer.addPage(page);¶
    }¶
¶
    f++;¶
  }¶
¶
  document.close();¶
  return outFile;¶
} catch(e) {¶
  return 'ERROR'¶
}" )

The function generates the pdf correctly but locks all the files except for the output file so I can't delete them.

I added

writer.flush();¶
writer.close();¶

It did not change anything.

 

Tried to add reader.close() but it generates an error.

 

 

Any idea ?

which version of iText??? 

 

There's abetter method using 

com.itextpdf.text.pdf.PdfConcatenate

 

you need to close the reader file at the end of the while loop...

Just now, john renfrew said:

yeah I just figured that out.

Thanks for the info about the concatenate function

There is also a way to do this without the export step, but right from the container field, but SM is a little broken on this method on high sierra at the moment. When thats fixed I'll get back on how.
