>             Project: Flink
>          Issue Type: Bug
>          Components: Build System
>    Affects Versions: 1.3.2, 1.5.0, 1.4.1
>            Reporter: Chesnay Schepler
>            Assignee: Chesnay Schepler
>            Priority: Minor
>             Fix For: 1.5.0, 1.4.3
>
>
> All modules that contain a {{package-info.java}} file (that do not contain annotations which applies to *all* instances in Flink) will always be recompiled by the {{maven-compiler-plugin}}.
> To detect modified files the compiler compares timestamps of the source and .class file. In the case of {{package-info.java}} no .class file is created if it doesn't contain annotations, which the compiler interprets as a missing .class file.
> We can add {{-Xpkginfo:always}} to the compiler configuration to force the generation of these files to prevent this from happening.
