title: Maven: resource binary changes file size after build
body: <p>I am using the appengine-maven-plugin to build my Java Google App Engine project.</p>
  
  <p>I include .p12 certificates in a WEB-INF sub-folder</p>
  
  <p>When I build my application, the filesize of the certificate increases by a few KB. This renders it invalid. I have seen the same happen to .jks certificates too.</p>
  
  <p>I have verified the validity of the certificate pre-build and used the same method to confirm the invalidity of the post-build certificate.</p>
  
  <p>Can anyone tell me why the file size is changing and why it is not simply copied to the WAR?</p>
  
  <p>Thanks for your help.</p>
