I've found the cause of the problem :
I've reduced my ant task to this code :

execute() {
log("getContextClassLoader() = " + Thread.currentThread().getContextClassLoader());
}

When I run it with ANT (1.5.3.1) I get
[test] Thread.currentThread().getContextClassLoader() = [EMAIL PROTECTED]

So It may be the same from a maven.xml script !

When I run "maven ndl:test" (maven 1.0.2) I get

ndl:test:
   [test] Thread.currentThread().getContextClassLoader() = *null*
BUILD SUCCESSFUL

Is there any reason for this, a workaround or anything to do ?

Hello,

I'm using maven 1.0.2 and try to create a plugin for an ant task, that itself uses Springframework.

As I get strange troubles, I've dropped all specific code to get only an ant task that creates a spring context.
The spring context is reduced to a single bean of type String.

When I run it as an ant task, it works fine, ie. the Spring context is loaded :
   >ant
   Buildfile: build.xml
     test:
   Trying to override old definition of task test
        [test] TEST !!!!
[test] 13 oct. 2005 17:33:06 org.springframework.beans.factory.xml.XmlBeanDefinitionReader loadBeanDefinitions [test] INFO: Loading XML bean definitions from file [D:\workspace\ant-maven-failure\Designer-context.xml]
...

When I run it from a maven.xml goal (ndl:test) it fails with a strange error :

   >maven -e ndl:test
    __  __

     ndl:test:

     BUILD FAILED

Does anybody have any suggestion to investigate and solve this ?

You can download the project from http://loof.free.fr/ant-maven-failure.zip (3Mo)
run "ant" and compare with "maven ndl:test"
