Create a custom SBT task to print the version

[BenFradet]

would remove the need for this:

scala-weather/.travis/deploy.sh

Line 17 in bfc3e3b

project_version=$(sbt version -Dsbt.log.noformat=true | perl -ne 'print "$1\n" if /(\d+\.\d+\.\d+[^\r\n]*)/' | head -n 1 | tr -d '\n')

What is the problem with the line? If you want to get rid of perl you could use

sbt -no-colors 'inspect actual version' | grep Setting | cut -d '=' -f2

[BenFradet]

I think I remember seeing a custom sbt task in another project that would just do this and that would let us do something like:

project_version=$(sbt myPrintVersion)

[oschrenk]

You have to wait for the next sbt release then. They will introduce print which prints to stdout instead of using the logger (which you have to parse)

See sbt/sbt#4341

[oschrenk]

Then you should be able to do sbt --error 'print version'.

Thanks, useful info 👍
