Suppressing or Redirecting Stacktraces from Workflow [message #1839840]

We are using the ant workflow implementation for coordinating builds. Occasionally, we execute speculative steps in eol and wrap them with an ant-level catch construct. This works ok from a functional point of view, but produces a substantial stack dump from the task as it fails. The stack dump is not very useful, as it does not refer to the eol program and its state, but rather to the state of the interpreter running the EOL. We would like to suppress this, but would like to do this declaratively, rather than subclassing the ant build logger that relays this information.

Is this possible?

Hi Jörn,

In my setup, the exception also contains information about the location of the exception in the EOL program. Could you please check with the latest interim version of Epsilon and let me know if the problem persists?

main:
[epsilon.eol - tree.eol] EXCEPTION: Property 'foo' not found in object t_tree
[epsilon.eol - tree.eol] 	at (.../tree.eol@1:0-1:11)
[epsilon.eol - tree.eol] 	at (.../tree.eol@1:0-1:22)
[epsilon.eol - tree.eol] 	at (.../tree.eol@1:0-1:22)
[epsilon.eol - tree.eol] 	at (...tree.eol@1:0-1:22)
[epsilon.eol - tree.eol] 	at (.../tree.eol@1:0-1:22)
[epsilon.eol - tree.eol] 
[epsilon.eol - tree.eol] 	at org.eclipse.epsilon.eol.execute.introspection.java.JavaPropertyGetter.invoke(JavaPropertyGetter.java:60)
[epsilon.eol - tree.eol] 	at org.eclipse.epsilon.eol.dom.PropertyCallExpression.execute(PropertyCallExpression.java:76)

Best,

Thanks. We will have to consider this carefully, as we want to keep disturbance in the system low.

I have just tried out the advice to switch to intermediate. I see the changed IUs, but I am on not seeing a difference in the behaviour of the build. Is there anything else that I need to be aware of to achieve the interpreter log behaviour? Flags? Properties? Environment variables?

Hmm - that's odd. Could you please share a minimal example we can use to reproduce the behaviour you're encountering?

Best,
Dimitris
