Brainstormed and unordered list of requested features of Ant2: * namespace support so different concerns can occupy different namespaces from ant (thus SAX2/JAXP1.1) * Java2 * The ability for GUI/IDE tools to integrate easily with object model without reinventing the wheel and writing their own parser (which antidote was forced to do). Two suggested solutions were allowing GUI developers to extend object model (ie GUITask extends Task) or to have Task as interface (ie GUITask implements Task). This way the GUI tasks could be W3C DOM Elements, have property vetoers/listeners etc. * Fully interpreted at runtime. This almost requires some form of abstraction/proxy that stands in place of tasks till it is interpreted. This can be hashtables/simple dom-like model/whatever * provide utility classes to aid in building tasks. ie like up-to-date functionality abstracted * make ant-call a low cost operations so it can certain optional/template-like operations * allow facilities to build projects from multiple sources. ie CSS+xml or XSLT+ XML or database or from inside jars or normal build.xmls etc. * remove magic properties if at all humanly possible * make all tasks consistent and remove all deprecated methods * move to a system that allows docs to be generated - doc snippets should be included with the tasks they document. * allow documentation to be stored in .tsk jars * allow tasks to be loaded from jars. tasks should be indicated by either xml file in TSK-INF/taskdefs.xml or manifest file. * remove as much dependency on native scripts as possible. * clean object model (ie Project/Target/Task) * good event model to integrate well with IDE/GUI/whatever * better scripting/notification support so the hooks are available to send notifications at certain times. * allow all datatypes to be defined anywhere * make usage of particular filters/filtersets explicit in copy tasks * make facade tasks for things like javac (JikesImpl, ModernImpl etc) * seperate tasks into .tsk jars somehow. (Probably via function - ie java tasks, file tasks, ejb tasks). * unify multiple similar tasks to use similar forms (ie all the javacc type tools) * support for numerous frontends - from command line over GUI to servlets * make properties fully dynamic, i.e. allow their value to be reassigned Now there is a bunch of "controvertial" points. By controvertial I mean not everyone agrees or else there has not been enough comments to to judge reception * unify the namespace of all data types (ie properties + filesets + patternset + filtersets). * provide datatypes through property tag and remove need for seperate free standing entities. ie * make it possible to reuse taskengine for other things. ie Installshield type app, my cron-server and other task based operations. Currently no committer other than me has expressed positive or negative thoughts about this * make separate build files easy (ala AntFarm) and importing different projects a breeze * create the concept of workspace so that projects can be built in a DAG and thus enable projects like catalina/tomcat to have an easy build process. It also helps CJAN to a lesser degree and would partially solve the JARs in CVS thing. * provide support for CJAN * provide support for non-hardwired (ie loadable) converters. * provide support for non-hardwired (ie loadable) datatypes. * generate docs by anakia/XSLT * provide support for user defined task configurations - i.e. give users the ability to specify a default value for attributes (always use debug="true" in unless something else has been specified). Could be a CSS like language, could be a element ... * support more control over the properties that are going to be passed to subprojects (modules) * keep build file syntax as compatible to Ant1 as possible - i.e. don't break something just because we can. * keep the interface for Tasks as similar to the one of Ant1 as possible - i.e. don't break something just because we can. * tasks provide some way to identify their attributes from the outside. Possible solutions include a special method like getProperties(), an external describing file shipping with the task class or special javadoc comments parsed by a custom doclet.
