This issue is unfortunately quite important for Spring Boot users and as a result we're going use Maven Compiler 3.5.0 in the Spring Boot 1.4 parent POM. I'd love to be able to upgrade to 3.5.2 when it's available so please let us know if there's anything we can do to help fix this issue.

> After upgrading the Maven Compiler Plugin to 3.5.1, I see compilation errors with builds that work on 3.5. The symptom is that classes generated by an APT plugin are not visible on the test class path when {{target/generated-sources/annotations}} is used as output folder.
> I'll attach a sample project that shows the failure if you run {{mvn clean test-compile}}.
> Two things make the project work:
> 1. Downgrade to 3.5 (which makes me think any of the fixes made for MCOMPILER-240 has to do with this).
> 2. Change {{annotations}} segment  of the output path to something other than {{annotations}}.
> Especially the latter puzzles me as it seems like this path is explicitly not added to the test compile classpath.
