the first good thing is that u realized this!
or did someone else have to tell u?
anyways: it is good practice to tell the others via mailing list that u
are working on the problem and also to tell them how long it probably
will take u.
sometimes we have >1 persons affecting a build. that personal needs to
communicate with each other and determine who caused the problem. and
than u need to work with high priority on the problem until it is solved.
in case u need to make large modification to the code where u expect the
build to fail, send a notice of this on the mailing list as well. again,
an estimate is greatly welcome :)
during a time the build fails other developers not involved in fixing
the build should refrain from checking in code.
the reason for this, is that the longer it takes to fix the build on
bamboo, the harder it is to detect the particular check-in causing the
problem b/c of masking errors.
