[jira] (MCOMPILER-187) incremental stuff detect changes even if nothing has changed means too much compilation

    [ https://jira.codehaus.org/browse/MCOMPILER-187?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=323456#comment-323456 ] 

David Barri commented on MCOMPILER-187:

[INFO] Changes detected - recompiling the module!
[INFO] Compiling 258 source files to ...

I suggest that you take a look at the Scala incremental compiler. That has incremental compilation working properly (ie. correctly detects and only compiles changes).
