Before attempting to build the bootstrap build system please read etc/deliverables/README.TXT. You will also need Apache Ant version 1.6.1 or later. To build and install the antlib using the following command: $ cd avalon/tools/project $ ant -buildfile bootstrap.xml install The core antlib is now installed and we can use magic to build and package itself in a block archive. $ ant clean install To simulate a gump build of magic by magic $ ant -Dmagic.home=target/123 \ -Dgump.signature=123 \ -Dgump.resource.ant=lib/ant.jar \ -Dgump.resource.junit=lib/junit.jar \ -Dgump.resource.ant-junit=lib/ant-junit.jar \ -Dgump.resource.ant-nodeps=lib/ant-nodeps.jar
