A new topic, 'Request for Enhancement: Multiple include', has been made on a
board you are watching.
You can see it at

The text of the topic is shown below:
With LiquiBase 1.9.1 I am having difficulty with multiple <include> tags
pointing to the same change log file. I get the error, "1 change sets had
duplicate identifiers". Has this been addressed in 2.0 beta?
According to the manual,

Currently there is no checking for looping changelogs or double inclusion of
changelogs.
If you include a changelog twice, you shouldn't run into problems because the
second time around, LiquiBase will know that the changeSets have been run and
won't run them again ...
I have multiple projects, say A, B, C and D. Projects A and B may be deployed
independently or together. They both have project C as a dependency. The
change logs for A and B each include the change log for C. The change log for
project D includes the change logs for projects A and B. The change log for
project D gets the error "1 change sets had duplicate identifiers".
A simple test verifies that double inclusion produces this error. (Copied
below.)
A workaround is to move the inclusion of changelog C to changelog D. However,
that means that all dependencies must propagate to the top level.
Can this be fixed?
Thanks,
