Réda Housni Alaoui commented on MBUILDCACHE-45:
-----------------------------------------------
I have the same issue with the sonar-maven-plugin. The latter expects .class
files in target folders.
> Compiled classes are not copied/restored to target, causing higher phase
> builds to fail

> Key: MBUILDCACHE-45
> URL: https://issues.apache.org/jira/browse/MBUILDCACHE-45
> Project: Maven Build Cache Extension
> Issue Type: Bug
> Environment: windows
> Reporter: Miguel Ortega
> Priority: Major
> Attachments: maven-cache.zip
>
>
> +*Step to reproduce*+
> 1. Execute a first command on a pristine projet( NO CACHE has ever been
> stored)
> {code:java}
> mvn test{code}
> Results are cached (contrary to documentation that states that "cache will
> kick-in automatically on every lifecycle build of phase {{package}} or
> higher.") This could also be a feature since tests can be skipped if nothing
> changes.
> 2 . But if I run next:
> {code:java}
> mvn clean verify
> #OR
> mvn clean install{code}
> Then the build fails
> {code:java}
> [ERROR] Failed to execute goal
> org.springframework.boot:spring-boot-maven-plugin:3.0.2:repackage (repackage)
> on project demo: Execution repackage of goal
> org.springframework.boot:spring-boot-maven-plugin:3.0.2:repackage failed:
> Unable to find main class -> [Help 1]
> [ERROR]
> {code}
> The root cause seems to be that after "clean", the maven target directory is
> cleaned and even if the cache is detected, classes are not restored to the
> target folder anymore
> {code:java}
