Cannot make sbt compile fail

[mcavigelli]

Hi community

Thank you for maintaining this plugin.

We have a Java based playframework website. We would like to use checkstyle and make the compilation fail, as soon as we detect violations of the defined rules.

We have managed to run checkstyle on compilations. The violations are reported to the console
[info] Checkstyle complete. 12 warnings found. [success] Total time: 7 s, completed 20.01.2024, 16:46:38
We have set checkstyleSeverityLevel to Error and Info, the result is the same, always success.

I have tried on two computers / environments with the same result

1. sbt 1.9.7 (Debian Java 17.0.9), plugin 4.0.1, checkstyle 10.12.7
2. sbt 1.3.10 (Windows 11, openjdk 11.0.18), plugin 4.0.1, checkstyle 10.12.7

Thank you, Matthias

Hi community

The checkstyle task on its own behaves as expected. It is also reacts on the checkstyleSeverityLevel setting.
But when invoked through the compile task (Compile / checkstyle) := (Compile / checkstyle).triggeredBy(Compile / compile).value, it does not fail the compile task.

Not sure if my expectation was wrong or if this is a bug. Anyway, the desired behaviour can be done with two separate tasks:

sbt checkstyle
sbt compile
