Are there any tools for performing static analysis of Scala code? [closed]

Answer 1

There is a SBT plugin for PMD copy paste detector CPD.

Answer 2

There is now Scalastyle which does the job that Checkstyle does for Java. This includes not only formatting checks, but also some checks for known sources of bugs, such as a class which implements hashCode() but not equals.

There are currently about 40 checks, but we're adding them all of the time.

For more information, see www.scalastyle.org.

Answer 3

I'm having a lot of fun with Codacy (e.g. https://www.codacy.com/app/hejfelix/Frase/dashboard) for Open Source projects

Answer 4

scala copy paste detector, based on AST. Looking for copy-pasted subtrees/ASTs, and inform about it.

It's plugin for sbt.

Answer 5

FindBugs analyzes JVM byte codes, regardless of the tool that generated them. I've tried using FindBugs to check .class files generated by Scala. Unfortunately, FindBugs produced many warnings, even for trivial Scala programs.

Answer 6

Findbugs and other tools that are bytecode based will work, in the sense that they will find faults in your code. Unfortunately, the bytecode based approaches have been tuned against the output of the javac compilers, meaning they are likely to produce very high false positive rates, and miss basic issues, because Scala will be producing different idioms than the javac compiler.
