Hi All, I know Wartremover uses Scala compiler's built-in warning system. Do you know whether there is any SBT plugin or any other possibility to generate the XML or HTML report from the analysis?
That would be something similar to what Scapegoat offers, but it includes only this linter related inspections in the report. I want to find a way to collect the default and Wartremover's warnings.
Is there any SBT plugin making it possible? Do you have any other idea?
Hi
I am trying to disable the Var, Return and MutableDataStructures warts. This works fine with something like
wartremover -traverser org.wartremover.warts.Return -traverser org.wartremover.warts.Var -traverser org.wartremover.warts.MutableDataStructures file.scalaThe problem is that wartremover complains about the code
Using(Source.fromFile(name))which has nothing to do with the warts above. "Plain" Scala would accept this code (wart remover complains that the value Using is not found). Is this because Using was introduced in Scala 2.13, but wart remover seems to be only tested with Scala 2.12? Thanks!
[wartremover:TraversableOps] head is disabled - use headOption instead and doesn't suggest whether it's an error or warning
ExplicitResultTypes that automatically inserts the inferred type annotations on public members https://scalacenter.github.io/scalafix/docs/rules/ExplicitResultTypes.html I use it in several of my projects and it's worked pretty well in my experience
@rfan-debug no worries, I tried using wart remover v2.3.7 with sbt 0.13.8 and scala 2.11.11..works fine for me (refer this https://github.com/wartremover/wartremover/blob/da1e629e3367c0ec/docs/_posts/2017-02-11-install-setup.md)
Thank you! that's really helpful!
toString and StringPlusAny with wartremover. It works well, but we use a lot of integer/long/etc for metrics log, I get tons (several hundreds) of warning, which make it almost unusable. I would like to know if there is a way to tell wartremover "except integer"?
Hi, I am having a hard time trying to exclude files. As per the docs, I can use wartremoverExcluded.
However this doesn't work:
lazy val wartremoverSettings = Seq(
wartremoverWarnings in (Compile, compile) ++= Warts.allBut(Wart.Throw),
wartremoverExcluded ++= Seq(
sourceManaged.value,
baseDirectory.value / "common" / "src" / "main" / "scala" / "com" / "tango" / "charlie" / "clients" / "Github.scala"
)
)Any pointer would help, Thank you.
Hi folks, I’m having issues with wartRemover working in vsCode / metals. It does work normally when I compile, but, when metals compiles it via bloop, I get this errors in metals.log:
ERROR bad option: -P:wartremover:only-warn-traverser:org.wartremover.warts.Anysbt 1.4.4
scala 2.13.4
I’ve added
addSbtPlugin("org.wartremover" % "sbt-wartremover" % "2.4.13”)in project/plugins.sbt
and
ThisBuild / wartremoverErrors ++= Warts.unsafein build.sbt
Equals wart that it also warns on Strings. Can I stop wart remover warning about String comparisons or is this an opinionated thing? i.e. Wartremover is implying I should wrap all my Strings in other types
I can see 2.13.4 has been added to github repo but there hasn't been a new release for that change. Just wondering how you got it working.

Hello guys
I've implemented custom wart and try to use it in the same project - have compilation error sayingscala.ScalaReflectionException: object com.{org}.warts.MyWart not found
I'm connecting it via settings:
lazy val wartSettings = Seq(
Compile / compile / wartremoverErrors ++= Seq(Wart.custom("com.{org}.warts.MyWart"))
)
is it a limitation or there is a workaround?
@DCameronMauch This is an IntelliJ issue. I was fixing it earlier by downgrading 2.4.13 to 2.4.10.
This is fixed already by IntelliJ. I raised an issue there some time ago.
May current working setup is SBT 1.5.2, Wartremover 2.4.13, IntelliJ 2021.1.1 with the latest Scala plugin.
All is fine.
Opened an issue for that on Github
If this issue was opened for Wartremover I would suggest to close it, as it is not valid due to above mentioned fix in IntelliJ.
