set the 'source' and 'target' attribute of <javac>. >java.lang.UnsupportedClassVersionError: >com/sun/tools/javac/Main (Unsupported major.minor version 49.0) That means, that a Java<=1.4 class (version 48) tries to instantiate a class that was compiled on Java5 (version 50). Usually you should try to compile the used class on the lower level. But com/sun/tools/javac/Main is part of the JDK (tools.jar). So recompiling is not possible (yet ;-) But I think your JAVA_HOME points to Java5 and therefore Ant adds Java5's tools.jar to its classpath ...
