I've built new version of SBT plugin against Bamboo 5.10. Also I fixed the problem with successful build not being correctly recognized.
Go to https://bitbucket.org/atlassian/bamboo-sbt-plugin/downloads for most recent downloads.

I don't know – looks correct. Maybe the sbt version is the issue (I'm speculating).
Can you try with an updated version of sbt? (i have 0.13.8)

Here is a part of Failing log from build log after adding the environment variables.

And here is a screenshot for my SBT task setting.

FYI, sbt version: 0.13.1
Scala: 2.10.2

Can u post log again after adding JAVA_OPTS setting in the Environment variables section?
Also make sure you only have "clean test" in the builder.sbt.target section, no other stuff.
Setting JAVA_OPTS like that worked for me on same version of Bamboo and same SNAPSHOT plugin...

I added 'JAVA_OPTS="-Dsbt.log.noformat=true -Dsbt.log.format=false"' to Environment variables, but I still have same problem.

Perhaps it would make sense if the sbt task plugin checks for this argument (and add it when missing), or make it check the sbt return code instead of text (if text is the only option, improve the text check?).

build 22-May-2015 03:00:31 [info] Passed: Total 34, Failed 0, Errors 0, Passed 34
build 22-May-2015 03:00:31 [success] Total time: 44 s, completed May 22, 2015 3:00:31 AM

Thats the weird check it's doing.

Do you have in the Environment variables something like this:

JAVA_OPTS="-Dsbt.log.noformat=true -Dsbt.log.format=false"

I installed SNAPSHOT version and tried to run the build, but SBT Task Plugin could not understand `[success] (color coded)` string, even after added to `Environment variables` :

-Dsbt.log.format=false

Bamboo 5.8.1 build 5866

Here is the build log: https://dl.dropboxusercontent.com/u/22797689/JIMPORT-CE-JOB1-20.log

Ah yes, that works as well. I already had a few options in Environment variables but I did not enclose them in JAVA_OPTS.

Thanks.
