Dave Moten commented on MBUILDCACHE-76:
---------------------------------------
So this will happen for a single module project as well (multi-module is a
distraction).
Fundamentally the build cache doesn't work in this circumstance because no
artifacts will be rebuilt and installed to .m2 (and they do not even exist at
that version).
Why don't we just include the versions in the checksum?

> Key: MBUILDCACHE-76
> URL: https://issues.apache.org/jira/browse/MBUILDCACHE-76
> Project: Maven Build Cache Extension
> Issue Type: Bug
> Affects Versions: 1.1.0
> Reporter: Dave Moten
> Priority: Minor
>
> When I run `mvn versions:set -DnewVersion=BLAH`, the build cache extension
> does not detect this and skips all modules in a multimodule project (and
> fails when it encounters a module that depends on one of the other modules (a
> maven plugin)).
> What should happen is that every module gets rebuilt.
> To duplicate
> ```
> git clone [https://github.com/davidmoten/openapi-codegen.git]
> cd openapi-codegen
> mvn clean install
> mvn versions:set -DnewVersion=1.2.3.4-SNAPSHOT
> mvn clean install
> ```
> Output:
> ```
