Kristian Rosenvold updated MSHARED-243:
---------------------------------------
Fix Version/s: maven-shared-utils-0.1
> add a way to calculate diffs of a directory at 2 different times
> ----------------------------------------------------------------
>
> Key: MSHARED-243
> URL: https://jira.codehaus.org/browse/MSHARED-243
> Project: Maven Shared Components
> Issue Type: New Feature
> Components: maven-shared-utils
> Reporter: Mark Struberg
> Assignee: Mark Struberg
> Fix For: maven-shared-utils-0.1
>
>
> For implementing the incremental build it should be possible to detect which
> files got created by a certain mojo execution.
> An example would be the maven-compiler-plugin which currently doesn't remove
> class files for Java sources which got deleted.
> The idea is to introduce a helper which can capture a snapshot of a certain
> directory (e.g. target/classes), then you do the mojo work (javac invocation
> with all source files) and take a capture of that very directory again.
> The tool will allow you to take a 'diff' and store the names of all the added
> files to a file in target/...
> The next time you invoke a build you can delete all those created classes by
> this very mojo-execution and so you do not have any left-overs.
