Hi,

Does Maven support incremental builds? After `svn up', the build is taking
time even without any updates from svn.

Thanks,
Praveen

Could someone please respond to the below query?

Regards,
Praveen

Alejandro,

Here is the sequence

1. 'svn get ....'
2. do a build
3. 'svn up' with no changes
4. do a build

Tasks (2) and (4) are taking almost equal time. I expected task (4) to be
much faster.

Praveen

Alejandro,

Here is the command I use for branch-0.23

mvn clean install package -Pdist -Dtar -DskipTests -Dmaven.javadoc.skip=true

Praveen,

Obviously, a "clean" target will wipe out all your existing build directories, and hence the other things start from scratch. That is your slowdown-causer.

Just remove the clean from that command and you're good to go.

Praveen,

One thing to be aware of with removing the clean is that I have run into situations, in both hadoop and in other projects, where an API changed as part of the update or something and maven did not realize it and did not rebuild something that depended on it.  I then got a runtime error and after doing a clean I got a compile error.  I have also seen situations where the tar.gz package for hadoop was not properly updated and after deploying, it did not have my fix in it.  It took me a long time to figure out why my fix did not work.  After doing a clean and rebuilding/redeploying everything worked just fine.  I have not had the time to dig though why that is happening or file any JIRAs on them.  Also it is rather rare, but if I want to be sure something has my changes in it I always do a clean first.
