Stephan, Here is a copy of my very recent email to the list describing the steps required to have Ant 1.5 as a dependency. The problem you are having should go away if you follow the steps below.
Even following the steps below, you will still have a few issues with the plugins using ant tasks that don't quite work the same way in Ant 1.5. I will be checking in all the required changes soon, after I figure out how to deal with commons-grant. -Peter Begin email ---------------------- Ok, finally have figured out the requirements to move to Ant 1.5 as a dependency. It was trickier than I first thought due to some wacky classloading and useless stack traces. 1) change jars.list to refer to ant 1.5 jars, including xerces 2.0.2 and xml-apis-1.0-b2. These are the jars distributed with ant official release. If you try xerces 2.0.0 or xml-apis-2.0.2, then Ant don't work. Also need to point to a grant jar that has no Ant classes in it. ( see below ) 2) change forehead.conf to refer to ant-1.5.jar, ant-optional-1.5.jar, xml-apis-1.0-b2 and xerces-2.0.2 3) Remove AntClassLoader.class and AntClassLoader$ResourceEnumeration.class from commons-grant-1.0-b1.jar Took me a while to figure that out. Thanks Bob. However, I don't know the correct way to fix this going forward. We need a grant jar without the Ant classes in it. We may not even need grant at all, but I need advice on how to remove the property wrapper stuff or what that actually does. Then we can decide what the grant dependency is. 4) Change dependencies in project.xml as follows: ant-1.4.1 --> ant-1.5 ant-optional-1.4.1 --> ant-optional-1.5 ( maybe remove grant ) xml-apis-2.0.2 --> xml-apis-1.0-b2 This last one is required to do, or else Ant fails. 1.0-b2 contains additional classes and I never have heard of a 2.0.2 release of xml-apis anyways. There are also a few minor task changes that are needed ( that I will make ) and we should be good to go with Ant 1.5. Waiting on some advice about what to do with grant and having the ant xerces and xml-api jars put in the repo... -Peter ----- Original Message ----- From: "Stephan Merker" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Friday, July 12, 2002 10:03 AM Subject: maven b5 and ant 1.5 > Hello, > > I'm trying to get maven b5 working together with ant 1.5. > However, I always get an exception like this: > > E:\maven\jelly>maven > __ __ > | \/ |__ Jakarta _ ___ > | |\/| / _` \ V / -_) ' \ ~ intelligent projects ~ > |_| |_\__,_|\_/\___|_||_| v. 1.0-b5-dev > > commons-jelly (commons-jelly) 1.0-dev > E:\maven\jelly > > [available] DEPRECATED - <available> used to override an existing > property. > Build file should not reuse the same property name for different values. > [available] DEPRECATED - <available> used to override an existing > property. > Build file should not reuse the same property name for different values. > [taskdef] [ERROR] java.lang.reflect.InvocationTargetException > [taskdef] [ERROR] at > sun.reflect.NativeMethodAccessorImpl.invoke0(Native M > ethod) > [taskdef] [ERROR] at > sun.reflect.NativeMethodAccessorImpl.invoke(NativeMet > hodAccessorImpl.java:39) > [taskdef] [ERROR] at > sun.reflect.DelegatingMethodAccessorImpl.invoke(Deleg > atingMethodAccessorImpl.java:25) > [taskdef] [ERROR] at java.lang.reflect.Method.invoke(Method.java:324) > [taskdef] [ERROR] at > com.werken.forehead.Forehead.run(Forehead.java:543) > [taskdef] [ERROR] at > com.werken.forehead.Forehead.main(Forehead.java:573) > [taskdef] [ERROR] Caused by: java.lang.NoSuchMethodError: > org.apache.tools.a > nt.AntClassLoader.getClasspath()Ljava/lang/String; > [taskdef] [ERROR] at > org.apache.tools.ant.Project.addTaskDefinition(Projec > t.java:897) > [taskdef] [ERROR] at > org.apache.tools.ant.taskdefs.Taskdef.addDefinition(T > askdef.java:82) > [taskdef] [ERROR] at > org.apache.tools.ant.taskdefs.Definer.addDefinition(D > efiner.java:232) > [taskdef] [ERROR] at > org.apache.tools.ant.taskdefs.Definer.execute(Definer > .java:162) > [taskdef] [ERROR] at org.apache.tools.ant.Task.perform(Task.java:317) > [taskdef] [ERROR] at > org.apache.commons.jelly.tags.ant.AntTag.doTag(AntTag > .java:185) > [taskdef] [ERROR] at > org.apache.commons.jelly.impl.DynaTagScript.run(DynaT > ... > > What I did was: > - get a fresh checkout of maven sources > - changed the dependencies to ant 1.5 > - modified bin/forehead.conf to load ant 1.5 > - bootstraped maven > > The exception occurs on the taskdef tag in the changelog plugin.
