Key: MWAS-43
URL: http://jira.codehaus.org/browse/MWAS-43
Project: Maven 2.x WebSphere 6 Plugin
Issue Type: New Feature
Environment: N/A
Reporter: Chris Graham
Assignee: David J. M. Karlsen
Attachments: MWAS-43.patch
Maven builds will be failed, sometimes unnecessarily either due to connection
issues to the DMgr process (which effects the WsAdminMojo) and quite often due
to bugs in the underlying implementation of ServiceDeploy (which effects the
ServiceDeployMojo).
Should these failures occur when performing a release, it is a nightmare to
clean up.
A typical failure of ServiceDeploy looks like this:

This is an intermittent error, as if you rerun it again, the error is not
likely to occur.
Note, this is different from a real build failure, which will always fail.
We have 34 (currently, soon to be over 50, and ultimately around 120) EARs all
generated by ServiceDeploy that all need to be built and released together. We
are guaranteed to receive one of these failures when building 34 ears, much
less 120.
So, this patch, generated against the 1.1 branch, introduces the retryCount
variable to allow us to retry a few times to work around failures such as
these. Projects with true failures, will still fail, the only impact is time.
The default is a retryCount of zero, allowing the default behaviour to be
preserved.
