Java Forum / Tools / October 2003Adding vizant tag to ant tag set via taskdef and antviz.jar?
Hi, I'm working with Ant1.5 (according to $ANT_HOME/welcome.html). I'm trying to extend the tag set of ant. I've never done it before. The tag I want to add is <vizant> which corresponds to a utility for building visualization of build.xml files. You will see a nice demo here: http://vizant.sourceforge.net/examples.html Based on my reading I need to do two things: 1. Find the appropriate .jar file for the <vizant> tag and add the .jar file to $ANT_HOME/lib. 2. Add an appropriate <taskdef> tag to the build file. So... I built a AntViz.jar file from an AntViz download. Here is my copy of AntViz: [root@localhost dist]# cd /home/dan/AntViz [root@localhost AntViz]# ls ./ classes/ README.txt ../ dist/ src/ actions.xml docbook-wrapper.xsl toc.xml antvizhelp.xml dockables.xml users-guide2002-0803.xml AntViz.props index.html users-guide2002-0803.xsl build/ lib/ users-guide.xml build2003-0803.xml license_dom4j.html users-guide.xsl build.xml LICENSE_jgraph word-index.xml changes.txt LICENSE.txt [root@localhost AntViz]# I used ant to create the AntViz.jar file: [root@localhost AntViz]# ant dist Buildfile: build.xml compile: [delete] Deleting directory /home/dan/AntViz/classes [mkdir] Created dir: /home/dan/AntViz/classes [javac] Compiling 28 source files to /home/dan/AntViz/classes [javac] /home/dan/AntViz/src/antviz/AntViz.java:863: warning: getFile() in org.gjt.sp.jedit.Buffer has been deprecated [javac] antBuildFileDir = currentBuffer.getFile().getParent();

To see whether class initialization is working, you can try something like java -classpath AntViz.jar antviz.AntViz If you get a message like Exception in thread "main" java.lang.NoSuchMethodError: main then class initialization worked and you can look elsewhere for the fault. --Mike Amling Hello again. Mike gave me a good clue! I responded to his posting with a simple experiment: [root@localhost ant]# cd $ANT_HOME/lib /sun1/jwsdp-1.2/apache-ant/lib [root@localhost lib]# ls ./ Console.jar tools.jar ../ dom4j.jar xercesImpl.jar AntFarm.jar ErrorList.jar xercesSamples.jar ant.jar jgraph.jar xml-apis.jar ant-optional.jar LatestVersion.jar xml-commons-resolver.jar AntViz.jar optional.jar XML.jar AntVizPlugin.jar QuickNotepad.jar xmlParserAPIs.jar CommonControls.jar SideKick.jar This put me in a good directory. Next, I tried the command line from Mike: [root@localhost lib]# java -classpath AntViz.jar antviz.AntViz Exception in thread "main" java.lang.NoClassDefFoundError: org/gjt/sp/jedit/EBComponent at java.lang.ClassLoader.defineClass0(Native Method) at java.lang.ClassLoader.defineClass(ClassLoader.java:537) at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:123) at java.net.URLClassLoader.defineClass(URLClassLoader.java:251) at java.net.URLClassLoader.access$100(URLClassLoader.java:55) at java.net.URLClassLoader$1.run(URLClassLoader.java:194) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:187) at java.lang.ClassLoader.loadClass(ClassLoader.java:289) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:274) at java.lang.ClassLoader.loadClass(ClassLoader.java:235) at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:302) [root@localhost lib]# I then went looking for the class: org/gjt/sp/jedit/EBComponent [root@localhost 4.2pre5]# cd /usr/local/share/jedit/4.2pre5 /usr/local/share/jedit/4.2pre5 [root@localhost 4.2pre5]# ls ./ AntViz.jar jars/ macros/ properties/ ../ doc/ jedit.jar modes/ startup/ [root@localhost lib]# jar -tf jedit.jar|grep EBComponent org/gjt/sp/jedit/EBComponent.class [root@localhost lib]# This is good; it looks like I found it. I retried the command line: [root@localhost 4.2pre5]# cp -p jedit.jar $ANT_HOME/lib [root@localhost 4.2pre5]# cd $ANT_HOME/lib /sun1/jwsdp-1.2/apache-ant/lib [root@localhost lib]# java -classpath AntViz.jar:jedit.jar antviz.AntViz Exception in thread "main" java.lang.NoClassDefFoundError: com/jgraph/graph/DefaultGraphCell [root@localhost lib]# It looks like I am making progress! I added another .jar to the command line's classpath: [root@localhost lib]# java -classpath AntViz.jar:jedit.jar:jgraph.jar antviz.AntViz Exception in thread "main" java.lang.NoClassDefFoundError: org/dom4j/Node [root@localhost lib]# I added another .jar: [root@localhost lib]# java -classpath AntViz.jar:jedit.jar:jgraph.jar:dom4j.jar antviz.AntViz Exception in thread "main" java.lang.NoSuchMethodError: main [root@localhost lib]# So, it appears that I need these jar files in my classpath: AntViz.jar jedit.jar jgraph.jar dom4j.jar I made sure the above jar files are located in $ANT_HOME/lib. Then, I retried the ant command which had failed before: [root@localhost ant]# cat build.xml <?xml version="1.0"?> <!-- A simple build.xml file --> <project name="x build.xml 01" default="main" basedir="."> <taskdef name="vizant" classname="antviz.AntViz"/> <classpath> <path location="/sun1/jwsdp-1.2/apache-ant/lib/AntViz.jar"/> </classpath> </taskdef> <target name="main"> <vizant antfile="build.xml" outfile="build.dot"/> <exec executable="dot" ><arg line="-Nfontname=cour -Tpng build.dot -o build.png"/></exec> </target> </project> [root@localhost ant]# ant Buildfile: build.xml No public no-arg constructor in class antviz.AntViz BUILD FAILED No public no-arg constructor in class antviz.AntViz Total time: 1 second [root@localhost ant]# I then looked at the antviz.AntViz class; I found only one constructor: public AntViz(View view, String position) { super(new BorderLayout()); console = getConsole(view, false); aps = new AntPrintStream(System.out, console.getView()); javaHome = System.getProperty("java.home"); AntViz.log("JDK HOME: " + javaHome); this.view = view; this.floating = position.equals(DockableWindowManager.FLOATING); readOptions(); toolPanel = new AntVizToolPanel(this); add(BorderLayout.NORTH, this.toolPanel); if (floating) { this.setPreferredSize(new Dimension(500, 250)); } } According to my IDE a "View" type is actually this: org.gjt.sp.jedit.View I'm not sure how to pass a org.gjt.sp.jedit.View type object to this constructor via ant so I gave up on using this jar file. I suspect that AntViz.jar could be used to connect jEdit to both ant and antviz which I might be interested in doing someday. Right now I just wanted to get a vizant tag working in my build.xml. I found another vizant jar file here: http://umn.dl.sourceforge.net/sourceforge/vizant/vizant.jar I inspected it after I copied it to $ANT_HOME/lib.
