You have to add your custom conflictmanager using the <classpath /> element in your settings.xml.
Here you can find a little example for adding a custom resolver: http://ant.apache.org/ivy/history/latest-milestone/settings/classpath.html hope this helps you getting started... regards, Maarten ----- Original Message ---- From: "Burcher, Greg" <gregory.burc...@netapp.com> To: ivy-user@ant.apache.org Sent: Mon, December 20, 2010 7:55:15 PM Subject: RE: Need StrictConflictManager to respect force We actually need this immediately so I will fully implement/verify and then I will also submit to jira. I could do with some help with a problem that I am having trouble resolving. I have coded my StrictConflictManager subclass and added my code in a jar in the ivy.classpath. I have actually added my jar to the org.apache.ivy v2.1.0 module and added my jar as a publication in the ivy.xml for the ivy module. The Ivy configuration documentation does not have examples, nor could I find any, on the exact syntax to set define a custom conflict manager. This is what I have in my ivysettings.xml: <typedef name="strict-with-force" classname="com.netapp.common.ivy.StrictWithForceConflictManager"/> <conflict-managers> <strict-with-force/> </conflict-managers> Later, in my project ivy.xml file, I have this: <conflict manager="strict-with-force"/> Does this all look correct in terms of syntax? When I run my build.xml from the linux command line, the xml in the ivysettings.xml file seems to parse and be handled fine. However, I get this error when my ivy.xml file is parsed: /u/burcher/myproject/build.xml:332: The following error occurred while executing this line: /u/burcher/myproject/build.xml:150: impossible to parse ivy file for /u/burcher/myproject/build.xml: ivyfile=/u/burcher/myproject/ivy.xml exception=java.text.ParseException: [unknown conflict manager: strict-with-force in file:/u/burcher/myproject/ivy.xml ] at org.apache.ivy.plugins.parser.AbstractModuleDescriptorParser$AbstractPar ser.checkErrors(AbstractModuleDescriptorParser.java:89) at org.apache.ivy.plugins.parser.AbstractModuleDescriptorParser$AbstractPar ser.getModuleDescriptor(AbstractModuleDescriptorParser.java:342) at org.apache.ivy.plugins.parser.xml.XmlModuleDescriptorParser.parseDescrip tor(XmlModuleDescriptorParser.java:103) at org.apache.ivy.plugins.parser.ModuleDescriptorParserRegistry.parseDescri ptor(ModuleDescriptorParserRegistry.java:86) at org.apache.ivy.plugins.parser.AbstractModuleDescriptorParser.parseDescri ptor(AbstractModuleDescriptorParser.java:48) at com.netapp.common.module.ParallelSubAnt.buildModuleItems(ParallelSubAnt. java:736) at com.netapp.common.module.ParallelSubAnt.doExecute(ParallelSubAnt.java:69 7) at org.apache.ivy.ant.IvyTask.execute(IvyTask.java:277) at org.apache.tools.ant.UnknownElement.execute(UnknownElement.java:291) at sun.reflect.GeneratedMethodAccessor4.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessor Impl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.apache.tools.ant.dispatch.DispatchUtils.execute(DispatchUtils.java:1 06) at org.apache.tools.ant.Task.perform(Task.java:348) at org.apache.tools.ant.taskdefs.Sequential.execute(Sequential.java:68) at ... Running my build.xml instead in eclipse, I see this error message: Error while resolving the ivy instance for ivy.xml in 'myproject': The ivy settings file 'file:h:/p4/netapp_ivy_repo/main/ivysettings.xml' could not be parsed: failed to load settings from file:/h:/p4/netapp_ivy_repo/main/ivysettings.xml: impossible to define new type: class not found: com.netapp.common.ivy.StrictWithForceConflictManager in [] nor Ivy classloader Error while resolving the ivy instance for ivy.xml in 'dfm-common': Here the error is in the ivysettings.xml file, as though my custom class cannot be found. I will continue to dig into these problems, but any suggestions would be appreciated.
