>                 URL:
>             Project: Maven 2.x Jar Plugin
>          Issue Type: Bug
>    Affects Versions: 2.0

> I typed a <description> element into my pom; the description spanned 2 lines, and
my text editor put a tab char at the beginning of the 2nd line.
> The project built correctly, but another project depended on the resulting jar.
> The compilation of the depending project failed with "invalid header" on the jar I'd
just compiled.
> When I looked at the jar's manifest, I saw the Specification-Title attribute had the
tab character still in it from the <description> element.
> Replacing the tab with spaces in the pom solved the problem.
> However, this was valid xml that caused a compilation problem, so I think it's a minor
bug with the jar production code.
> Note that the full description is trimmed before going into the manifest, so any 
> Easy to work around, but it would be nice if whitespace in the <description> element
were consolidated into spaces before copying to the manifest.
> Doesn't need any fancy layout stuff - just any multiple instances of tabs, spaces, lf
or cr should be replaced by a single space.
> Try (I haven't tried to compile this!):
> {code}
>     public String consolidateWhitespace(String input){
>         StringTokenizer st = new StringTokenizer(input);
>         StringBuffer rv = new StringBuffer();
>         while (st.hasMoreTokens()){
>             rv.append(st.nextToken() + (st.hasMoreTokens()?" ":""));
>         }
>         return rv.toString();
>     }
> {code}
