Intellij: SBT-based Scala project does not build with Java 9

Question

I've tried to switch my Scala/sbt based project to Java 9. If I compile the project with sbt, it works.

If I try to build the project with the Build option of IntelliJ, I get immediately the error

Error:Module 'xyz' production: java.lang.NoClassDefFoundError: javax/xml/bind/DatatypeConverter

I've tried to add the module as dependency

libraryDependencies += "javax.xml.bind" % "jaxb-api" % "2.3.0"

and added in the compiler settings of IntelliJ (javac as well the scala compiler)

  <option name="ADDITIONAL_OPTIONS_STRING" value="--add-modules java.xml.bind" />

but does not help, unfortunately.

Answer 1

In addition to the above answers.

If you are not using IntelliJ and running the program from sbt console, I found the following resolved the issue:

• Adding the following to your build.sbt:

  libraryDependencies += "javax.xml.bind" % "jaxb-api" % "2.3.0"

• Adding the import statement to your controller:

  import javax.xml._
