The current client will automatically select the correct set of scanners based on the content of your project folder. You can, however, force or disable a scanner using these parameters:
--scan-java=false will disable the Java scanner
--scan-nodejs=false will disable the NodeJS scanner
--scan-javascript=true will enable the Javascript/Web scanner (disabled by default)
--scan-ruby=false will disable the Ruby scanner
--scan-dotnet=false will disable the Dotnet scanner
--scan-scala=false will disable the Scala scanner
--scan-php=false will disable the PHP scanner
A value of “true” will force the scanner to run (and fail if conditions are not met).
