Ant is a build tool. For some tasks (for example javac, javadoc) the tools from the Java _Development_ Kit are required. If you run with just a Java _Runtime_ Environment most of its tasks could be used, but not all - hence the warning.
Set your JAVA_HOME to the installation path of your JDK. http://ant.apache.org/manual/install.html#installing "Optionally, set the JAVA_HOME environment variable (see the Advanced section below). This should be set to the directory where your JDK is installed." http://ant.apache.org/manual/install.html#advanced "When you need JDK functionality (such as for the javac task or the rmic task), then tools.jar must be added. The scripts supplied with Ant, in the bin directory, will add the required JDK classes automatically, if the JAVA_HOME environment variable is set."
