Java Generator is generating spaces in the package names [message #1803540]

Hi,

I am using papyrus 2018-12 (4.10) and the designer update site: http://download.eclipse.org/modeling/mdt/papyrus/components/designer/. I have created a UML model and I have managed to generate Java Project however, I have two issues:
1- The package names have spaces in them
e.g.
package com.reservation.model.Common Business Entities Domain.Calendar ABE;

2- the prefix which i have defined in the project stereotype of the package is defined as per the below. This means that other packages are not referenced correctly.
import com.reservation.model.;

I have looked everywhere for hints but I couldn't find any. Appreciate, your support Ansgar.

Thanks

Sorry for the late reply.
1. Right now, spaces in package names are not escaped (e.g. replaced by underscores). While this could be done, it is also problematic e.g. with respect to model / code coherence. So, my recommendation is to avoid UML package names that are non Java compliant. An option would be to use the international feature by using a label with spaces while keeping package name without spaces.

2. It's not clear for me how you applied the Project stereotype, i.e. which attributes did you fill? The objective is to control in which plugin/source folder the generated file are placed, but not to use a different package name than the one defined at the UML level.

Hi Ansgar,

Thanks for your reply. I like the option of using a label with space while keeping the package names without space. I've written a perl script to rename all of the packages to remove the spaces between name attribute. HYG.

use strict;
use warnings;
#use XML::Simple;
use XML::LibXML;

my $filename = $ARGV[0];

my $dom = XML::LibXML->load_xml(location => $filename);

my $e= $dom->findnodes( "//packagedElement");

foreach my $e (@$e)
{ print $e->nodeName;

if($e->nodeName eq "packagedElement")
{
# text needs to be trimmed or line returns show up in the output
my $text= $e->textContent;
$text=~s{^\s*}{};
$text=~s{\s*$}{};

# if( ! $e->getChildrenByTagName( '*') && $text)
# {
# print "=$text"; }
print "\n";

my @attrs= $e->findnodes( "./@*");
my $arrLength = scalar @attrs;
# print "the number of attributes found is $arrLength";
# or, as suggested by Borodin below, $e->attributes

foreach my $attr ($e->attributes)
{
# print "attribute: $attr \n";

if($attr->nodeName eq "name" and ($attr->value =~ / /) )
{

#print $e->nodeName, " ", $attr->nodeName. "=", $attr->value, "\n"; }
my $string = $attr->value ;
$string =~ s/\s+//g;

my $originalString = $attr->value;
print "$originalString will be replaced with $string\n";
$attr->setValue($string);
}
}

}
}
$dom->toFile("output.xml",1);
