I did some more research (dumping Thread.currentThread(),
IvyContext.getContext() and IvyContext.getContext().get(IvyTask.ANT...)
at miscellaneous places and narrowed it to the WeakReference keeping the
Project in the IvyContext._contextMap. As for Threads - all was going on
in a single thread.
IvyContext{
...
public Object get(String key) {
WeakReference ref = (WeakReference) _contextMap.get(key);
// System.out.println("ICTX GET "+key+" | "+ref
+"|"+Thread.currentThread()+"|"+this);
return ref == null ? null : ref.get();
}
...
}
With comment turned off the WeakReference is dead sometimes (though it
shouldn't be as the Ant Project for sure is still accessible by the main
Ant process). With comment turned on the WeakReference is alive when it
is expected to be alive and everything passes smoothly.
Funny thing is that adding a comment in the getContext() new context
creation block also helps.
I'm not sure whether this is a problem with jvm or something else. The
WeakReference seems like a good idea to me for keeping Project, though
it might be stored directly with
Ivy*(IvyTask){
...
execute(){
setProjectInContext
realwork
unsetProjectInContext
}
...
}
Unless there are things in the background of Ivy that last past the
execute task and we need it to be Ant project aware.

Added a random comment. But now it is more predictable.

No - and as for now it seems to me like no Ivy problem.
As for my build:
structure of the project:
lib/
#static repository in the SVN
build/
#local ivy cache
#temporary repo for integration things
yadda-common/trunk/
# subproject with no internal deps
yadda-services/trunk/
# subproject with yadda-commmon as internal dep
DeskLight/trunk
#project with yadda-services as internal dep.
ivysettings:
<ivysettings>
<!-- <properties file="build.properties"/>-->
<settings defaultResolver="yadda" defaultCache="${ivy.cache.dir}"/>
<triggers>
<ant-call target="trigger" event="pre-resolve-dependency"
prefix="event."/>
</triggers>
<resolvers>
<chain name="yadda">
<filesystem name="local">
<ivy
pattern="${ivy.repo.dir}/[organisation]/[module]/ivys/ivy-[revision].xml"/>
<artifact
pattern="${ivy.repo.dir}/[organisation]/[module]/[type]s/[artifact]-[revision].[type]"/>
</filesystem>
<filesystem name="libraries">
<artifact
pattern="${yadda.lib.repo}/bin/[artifact]-[revision].[ext]" />
</filesystem>
</chain>
</resolvers>
</ivysettings>
target trigger in both DeskLight and yadda-services:
<target name="trigger" depends="init">
<var name="ivy.revision" unset="true"/>
<var name="revision" unset="true"/>
<ivy:findrevision organisation="${event.organisation}"
module="${event.module}" revision="${event.revision}"
property="revision"/>
<if>
<not><isset property="revision"/></not>
<then>
<echo message="BUILDING"/>
<delete>
<fileset dir="../lib">
<include name="${module}-*"/>
</fileset>
</delete>
<ant dir="${root.dir}/${event.module}/trunk/build/"
antfile="build.xml" target="${event.module}.publish"
inheritall="false">
<property name="mode" value="local"></property>
</ant>
</then>
<else>
<echo message="found revision for ${event.module} :
${revision}"/>
</else>
</if>
</target>
and the publication task depends on standard resolve,retrieve - and
therefore is recursive from the point of view of build.
Best Regards.
