Cannot publish snapshots using universal:publish

[matthughes]

Using SBT 0.13.5. Am able to publish regular artifacts on my Bamboo/Nexus system, but can't publish projects using 'universal' plugin.

These are snapshot builds and I took the same code he used to forcefully set isSnapshot, yet still getting the same error.

I double-checked 'isSnapshot' is set in consoleProject:
scala> (isSnapshot).eval
res0: Boolean = true

Here is the stack:

[muuki88]

This looks more like a nexus/bamboo file naming issue. The exception states, that the file
already exists, but it's not allowed to overwrite it.

java.io.IOException: destination file exists and overwrite == false`

Can you post a minimal build.sbt reproducing this issue? And the version
of your nexus running?

[matthughes]

Nexus version is 2.8.1-01.

I will have to get back to you at minimizing the issue.

[jsuereth]

@muuki88 We're failing to appropriately set the "overwrite" flag if isSnapshot setting is true in our publish settings. I can probably issue a fix shortly.

[muuki88]

Nice, we already have some small fixes for a next release.

[jsuereth]

K, I have the fix posted, but an issue: I know the settings/method doesn't exist in sbt 0.13.0 and previous, so this is a 0.13.1+ change....

Are we ok with that, or is master still the 0.7.x series?

[muuki88]

We should move on. I already created the v0.7.x branch, which we should no start to use to
release 0.7.x releases. So we drop scala 2.9.2 and sbt 0.12.x in master, right?
I also created a label v0.7.x, which marks pr/issues which changes are compatible with this branch.
