title: Littlemonkey QRcode scanner library patch issue while generating cn1lib library
body: <p>I downloaded QRScanner project from <a href="https://github.com/littlemonkeyltd/QRScanner" rel="nofollow noreferrer">https://github.com/littlemonkeyltd/QRScanner</a>
  and replace "codename1.arg.android.xapplication=" line in codenameone_library_appended.properties file. While building the library, it gives following error.</p>
  
  <pre><code>E:\QRScanner-master\src\org\littlemonkey\qrscanner\QRScanner.java:27Stubbing 
  Class: E:\QRScanner-master\build\stubs\org/littlemonkey/qrscanner/NativeScanner.java
  : error: package com.codename1.ext.codescan does not exist

  <p><strong>Update 1:</strong> I have added the cn1-codescan.cn1lib dependencies but same problem as above exists...</p>
  
  <p>-Unzipped cn1-codescan.cn1lib and kept main.zip inside lib folder</p>
  
  <p>-changes in build.xml</p>
  
  <pre><code>&lt;target name="-pre-compile"&gt;
      &lt;echo&gt;Compile is forcing compliance to the supported API's/features for maximum device compatibility. This allows smaller
      code size and wider device support&lt;/echo&gt;
      &lt;mkdir dir="build/tmp"/&gt;
      &lt;javac destdir="build/tmp"
          source="1.5"
          target="1.5"
          bootclasspath="lib/CLDC11.jar"
          classpath="lib/main.zip:${javac.classpath}:${build.classes.dir}"&gt;
          &lt;src path="${src.dir}"/&gt;
      &lt;/javac&gt;        
  &lt;/target&gt;

  <p>nbproject/project.properties file:</p>
