Empty output for help:evaluate

[wendigo]

This returns nothing:

mvnd --quiet help:evaluate -Dexpression=project.version -DforceStdout

This returns a version:

./mvnw --quiet help:evaluate -Dexpression='project.version' -DforceStdout
450-SNAPSHOT%

I think that issue could be a fact that echo is not new-line terminated.

When the output is redirected to file -Doutput=./file file is populated correctly so I think that this is a new line thingy

I guess this is on 1.0.0 ?

[wendigo]

Yep, 1.0.0. It works with --raw-streams as a workaround

Hey, I want to do a similar thing:

REVISION_VERSION="$(./mvnw --raw-streams help:evaluate -Dexpression=revision -DforceStdout -q)"

I already use --raw-streams but it does not work.

When I run it directly with mvn instead it writes the revision in a sapate (new) line

but with mvnd --raw-streams it doesn't write it out at all but also some other lines are missing

Ok, I figured out a solution, I could fix it by adding --non-recursive
