enable discoverers' stack-trace / activity-logging [message #1224668]

hi all

I'm starting with modisco by now

I want to know if there's a way to enable stack-trace / activity logging when running org.eclipse.java.discoverer.javaToKDM

I'm running this dicoverer and hour ago and don't know if it hanged already or is still running

Hello,

If you have set the "Serialize Target" parameter to true (cf. MoDisco documentation), you should see the created model/file in your workspace (default path is the same of the Java model's or Java project's one, as taken as input) when the discovery actually ends.
Is it the case?

Hi Hugo

well, these are the steps I took

1) Discover Java Project
this generates the AppSGPTI_java.xmi file
no problem there
then, right-click on the AppSGPTI_java.xmi file and select
2) Discover KDM Model from Java Model
this one take almost one hour and forty minutes till "java heap space" appeared

then I tried with
===========
1) Discover KDM Model from Java Project
"Error in discovery: Error discovering KDM model (see error log)
but I don't find the log file

then I tried
========
1) Discover Java and Inventory Model from Java Project
ELEMENTS_TO_ANALYSE: AppSGPTI
DEEP_ANALYSIS : true
SERIALIZE_TARGET : true

this one generates me three files
a) AppSGPTI_java.xmi
b) AppSGPTI_java2kdm.xmi
c) AppSGPTI_kdm.xmi

now... which file should I took: "a" or "b" ?

sorry I didn't specify the tools I'm using
Eclipse Kepler Modeling with MoDisco and Papyrus (with all its additional components)

In the first two cases you mention, it seems that your Eclipse is running out of memory during the discovery process (the Java project, and so the corresponding Java model, are probably quite big).
Have you tried to allocate more memory to the JVM when launching your Eclipse workbench?

In the third case (Discover Java and Inventory Model from Java Project), this is probably not what you are looking for if your goal is to produce a KDM model.

OK, so it is not really an Eclipe memory problem I guess Smile

Could you try by setting "Deep Analysis" to false when discovering the initial Java model?
The obtained model would then be sufficient (and smaller) to generate the KDM model.

ok, I'll tried
but I will need "Deep Analysis" because of the project's complexity and redundant code on it
