Jigar Joshi commented on MCOMPILER-213:
---------------------------------------

For time being if I want to fix it against what should I compare pom.xml's file modified timestamp ?

>             Project: Maven Compiler Plugin
>          Issue Type: Bug
>    Affects Versions: 3.0, 3.1
>         Environment: any
>            Reporter: Jigar Joshi
>            Priority: Minor

> Background:
> we are using maven build to build around 200 project tree, change in one single module costs building whole tree, to avoid it we switched to incremental build and I wrote a plugin that will periodically do full clean build after configurable period of time
> Issue:
> maven-compiler-plugin supports incremental compilation and only compiles the source that was modified that is nice feature, however it is not quite working well in following cases
>  - if there is a change in pom.xml (for example:change in dependency scope), it doesn't detect it as change and doesn't recompile that and all effecting projects
> {{org.apache.maven.plugin.compiler.AbstractCompilerMojo.isDependencyChanged()}} should cover it
> Verified this on revision {{1495788}}
