Im guessing that the gentoo developers are familar with this but I only just found it this out so.....<br><br>Ant 1.7 allows the declaration of system variables &#39;ant.build.javac.source&#39; and &#39;ant.build.javac.target
&#39; that will be used as defaults for javac and javadoc tags.<br><br>What will be the impact of this feature on our present build system?<br><br>Are we planning eventually to scrap our build.xml rewriting or even rewrite 
build.xml files to remove -source , -target attributes?<br>
