Re: could not start merlin from main method

You are right! It's something with dependencies, when I've declared in
eclipse 4 dependencies all was right and merlin was successful started
 <classpathentry kind="lib"
path="C:/Programming/merlin/3.3/system/avalon-repository/jars/avalon-reposit
ory-main-2.0.0.jar"/>
 <classpathentry kind="lib"
path="C:/Programming/merlin/3.3/system/merlin/jars/merlin-api-3.3.0.jar"/>
 <classpathentry kind="lib"
path="C:/Programming/merlin/3.3/system/avalon-framework/jars/avalon-framewor
k-api-4.2.0.jar"/>
 <classpathentry kind="lib"
path="C:/Programming/merlin/3.3/system/avalon-repository/jars/avalon-reposit
ory-cli-2.0.0.jar"/>

but then when I've got the Kernal I want to get a component from it. So I
used Kernal.locate() method, but Eclipse tells me this

--- The type org.apache.avalon.composition.model.DeploymentModel cannot be
resolved.
--- It is indirectly referenced from required .class files
TestExecMerlin.java testmerlinwithmain/src/test line 70

ok, then I added lib for Ecpse
<classpathentry kind="lib"
path="C:/Programming/merlin/3.3/system/avalon-composition/jars/avalon-compos
ition-api-2.0.0.jar"/>

error in Eclipse disappeared but when I tried to run main I've got this ! :(

and if I add all libs from system merlin dir then I've got the same message
as I wrote at the beginning.
And I don't know what I should to do if I want run it from Eclipse!
