[ http://jira.codehaus.org/browse/MAVEN-1125?page=comments#action_71100 ] Andy Jefferson commented on MAVEN-1125: --- If I take a very simple Java app that accepts input on System.in and reads it using a BufferedReader and does nothing more complicated then using fork=false will work :-) Sadly I want to do something more complicated. When I bring in other things (like XML parsing) then I get the xml-apis messages. I then add your jars to the dependencies and they get resolved (why I should have to do this is another issue since I haven't specified ANYTHING in project.xml to impose any restriction on XML parsing. I simply selected to run with JDK1.4.2_11 ... all other choices were made by Maven itself. My project.xml contains entries for log4j, jpox, and javax.jdo/jdo2-api ONLY). I then bring in reflection to my (simple) app. It then gives Caused by: java.lang.NoClassDefFoundError: sun/reflect/ConstructorAccessorImpl at sun.misc.Unsafe.defineClass(Native Method) at sun.reflect.ClassDefiner.defineClass(ClassDefiner.java:45) at sun.reflect.MethodAccessorGenerator$1.run(MethodAccessorGenerator.java:381) at java.security.AccessController.doPrivileged(Native Method) at sun.reflect.MethodAccessorGenerator.generate(MethodAccessorGenerator.java:377) at sun.reflect.MethodAccessorGenerator.generateConstructor(MethodAccessorGenerator.java:76) at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:30) at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:27) at java.lang.reflect.Constructor.newInstance(Constructor.java:274) at org.jpox.util.ClassUtils.newInstance(ClassUtils.java:70) so Maven (1.0.2) is doing something with the CLASSPATH and basic JDK classes (since they are part of the JDK i am using and that Maven is running with) are no longer found whereas they are by using a plain Ant (1.6.1) run with fork=false. *This is the issue*.

[ http://jira.codehaus.org/browse/MAVEN-1125?page=comments#action_71099 ] Andy Jefferson commented on MAVEN-1125: --- Hi Arnaud, so if i dont want to fork the JVM (and I dont see why I should since I want console input from my sample application), what do i need to do in maven.xml ? or project.xml ? I have (in maven.xml) With fork=false I just tried adding your versions of xml-apis, xml-resolver, xercesImpl to project.xml (previously I had nothing specified for those -- just entries for my own app jars) and I get java.lang.NoClassDefFoundError: sun/reflect/ConstructorAccessorImpl (using JDK 1.4.2_11) With fork=true, then it never reads the console input. What do i do to get Ant to read from the console when fork=true ? What do I specify in this setInputHandler ? (in the above maven.xml snippet) All I want to do is run a sample (Java) app that uses console input via Maven. It works via an Ant task (using fork=false) so I dont see a good reason why not with Maven. > ant:java fork issues > > > Key: MAVEN-1125 > URL: http://jira.codehaus.org/browse/MAVEN-1125 > Project: Maven > Issue Type: Bug >Affects Versions: 1.0-rc2 > Environment: Linux, JDK1.4.2 >Reporter: Andy Jefferson > > I have a Java app that I want to invoke via Maven.

Arnaud Heritier commented on MAVEN-1125:
Hi andy,
I'm sorry but we need to force maven and its plugin to use a known version
(for us) of the XML APIs (xml-apis 1.3.03 + xml-resolver 1.1 + xercesImpl
2.8.0). For that we are defining these APIs in the endorsed libraries which
create a conflict with your own if you don't fork the JVM.
As said in the issue MAVEN-1425, did you try to use
${pom.getAntProject().setInputHandler(...)} ?

I read the "more succinct report" that it refers to and the "solution" does nothing for me. How am i to use ant:java with fork=false and avoid the xml-apis messages ? How am I to use ant:java with fork=true and get the input ? What do i pass in to the "InputHandler" ? Point me to a doc at least that defines this, please Is this fixed in Maven 1.1-beta-X for ant fork=false ? No, I dont use Maven 2 yet. Would it work there ? > ant:java fork issues > > > Key: MAVEN-1125 > URL: http://jira.codehaus.org/browse/MAVEN-1125 > Project: Maven > Issue Type: Bug >Affects Versions: 1.0-rc2 > Environment: Linux, JDK1.4.2 >Reporter: Andy Jefferson > > I have a Java app that I want to invoke via Maven.
