Question

Looked at several post on stackoverflow as well as other sources (online + ANT definition guide book) but none of them helped so far. I can’t exclude the file from compiling.

I have just one file that wants to exclude from compiling and ANT documentation is not really telling the detail.
I’m trying to exclude HTMLParser.java from compiling.
Also tried using excludesfile too. But it still complies HTMLParser.java

I wrote simple ANT to examine trying different variation below.

Could anyone tell me what’s wrong?

<javac srcdir="${utilitiesSrc}" destdir="${dest}">
      <excludesfile name="C:\Program Files\Apache Software Foundation\Tomcat 6.0\webapps\head_first\src\com\masatosan\utilities\HTMLParser.java" />
</javac>

<project 
     name="CompileMasatosan"  
     default="main"
     basedir="C:\Program Files\Apache Software Foundation\Tomcat 6.0\webapps\head_first\src\com\masatosan">

     <property name="dest"
    location="C:\Program Files\Apache Software Foundation\Tomcat 6.0\webapps\head_first\WEB-INF\classes" />


     <property name="utilitiesSrc" 
        location="C:\Program Files\Apache Software Foundation\Tomcat 6.0\webapps\head_first\src\com\masatosan\utilities" />

    <javac srcdir="${utilitiesSrc}" destdir="${dest}">
         <exclude name="C:\Program Files\Apache Software Foundation\Tomcat 6.0\webapps\head_first\src\com\masatosan\utilities\HTMLParser.java" />
    </javac>
</project>

The HTMLParser.java I believe has no dependency since I commented all lines out except class declaration line.

HTMLParser.java

package com.masatosan.utilities;

public class HTMLParser {
/*  commenting out since Eclipse doesn't like some characters :(

    public static final String escapeHTML(String s){
           StringBuffer sb = new StringBuffer();
           int n = s.length();
           for (int i = 0; i < n; i++) {
              char c = s.charAt(i);
              switch (c) {
                 case '<': sb.append("&lt;"); break;
                 case '>': sb.append("&gt;"); break;
                 case '&': sb.append("&amp;"); break;
                 case '"': sb.append("&quot;"); break;
                 case 'à': sb.append("&agrave;");break;

                 // be carefull with this one (non-breaking whitee space)
                 case ' ': sb.append("&nbsp;");break;         

                 default:  sb.append(c); break;
              }
           }
           return sb.toString();
    }
    */
}//

UPDATE

As suggested in the comment, I change the excludesfile name attribute to relative path of srcdir and that was it! So the snipped looks like:

<javac srcdir="${utilitiesSrc}" destdir="${dest}">
      <excludesfile name="HTMLParser.java" />
</javac>

Answer 1

Obvious thing I imagine you have already checked is that nothing that you are compiling has a dependency in HTMLParser. If this is the case, the javac command will compile the file anyways.

To clarify, the problem above was using an absolute path with the exclude property. When a srcdir is given, ant creates an implicit path with exclude file names.
