Re: Cannot use my ant task as a maven plugin : classloader issue
!
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() =
sun.misc.Launcher$AppClassLoader@53ba3d
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 ?
Nico.

Re: Cannot use my ant task as a maven plugin : classloader issue

Posted by Nicolas De Loof <ni...@capgemini.com>.
That sounds like a classloader issue, but I've reduced the problem to a
minimal project that has NO dependency (expect ant 1.5.3.1).
The maven.xml only defines the ant task (that is in target/classes) and
invoke it.
You can try it by downloading :

Re: Cannot use my ant task as a maven plugin : classloader issue !
Posted by Arnaud HERITIER <ah...@gmail.com>.
Hi Nicolas
In maven 1.X there's 2 classloaders
The root classloader where is ant and the root.maven classloader where is
maven and its dependencies.
If you use an ant task which need a dependency you must add the in the root
classloader to allow ant to find it.
In your POM these dependencies must have :
<properties>
<classloader>root</classloader>
</properties>
Also, you can take a look at this issue :
http://jira.codehaus.org/browse/MAVEN-1712
