sbt 1.2.8 generates a synthetic configuration instead of failing

• I’ve read the CONTRIBUTING guidelines

steps

cd /tmp
mkdir sbt101
cd sbt101
touch build.sbt

Add the following content to the file

ThisBuild / version := "1.0"

lazy val db = project.settings(
  version := "2.0",
)

lazy val business = project.settings(
  version := "3.0"
)

• Save and open up a terminal
• Run the following command

sbt

• When you are in sbt console, run the following commands

sbt:sbt101> business/version
[info] 3.0

sbt:sbt101> business:version
[info] business / Business / version
[info] 	3.0
[info] db / Business / version
[info] 	2.0
[info] Business / version
[info] 	1.0
sbt:sbt101>

sbt:sbt101> db/version
[info] 2.0
sbt:sbt101> db:version

[info] business / Db / version
[info] 	3.0
[info] db / Db / version
[info] 	2.0
[info] Db / version
[info] 	1.0
sbt:sbt101>

problem

• The output from db/version do not match with db:version.
• sbt generates a synthetic Configuration which does not exist. example? see Business and Db above

expectation

• The outputs from db/version and db:version(and other commands alike) should have matched their outputs.
• Instead of creating a synthetic Configuration, it should have failed. The current output leads to confusions (and may be wrong as well, can’t say for sure)

notes

• Thanks to @dwijnand for the help on gitter chat and helping out on this issue.

sbt version: 1.2.8

Agreed.

No, “it should have failed” is what I expect.
