java.lang.NoClassDefFoundError: javax/xml/bind/DatatypeConverter

Question

After installing JDK9, I get this exception when running my Scala projects. Upgrading Scala to 2.12.2 also didn't resolve my problem.

You might want to **[move to using `jaxb-api:2.3.0`](https://stackoverflow.com/a/46221811/1746118)** to solve this ideally. — Naman, Sep 20 '17 at 15:27

You can add dependencies in maven

<dependency>
    <groupId>javax.xml.bind</groupId>
    <artifactId>jaxb-api</artifactId>
    <version>2.3.0</version>
</dependency>

The java.xml.bind module is not resolved by default when running code on the module path. This means that if you depend on JAXB then you need to run with --add-modules java.xml.bind or else deploy JAXB on the class path (or module path).

Update: The "Modules Shared with Java EE Not Resolved by Default" section of JDK 9 Migration Guide provides more information on this topic.

Or `--add-modules java.se.ee` – ZhekaKozlov Mar 26 '17 at 01:50

in theory this is the solution, but how do you ask scala/sbt to add this argument when they run java? – Aero Wang Nov 17 '17 at 08:32
What do you think about ```javaOptions in ThisBuild += "--add-modules=ALL-SYSTEM"``` – Epicurist Jan 24 '18 at 15:14
```javaOptions in ThisBuild += "--add-modules=java.xml.bind"``` would be better. Do mind the equal sign! Tested with Java version "9.0.4" – Epicurist Jan 24 '18 at 15:44
@AeroWang did you find an answer to your question? – Christopher Peter Mar 15 '18 at 20:47
@ChristopherPeter no I gave up – Aero Wang Mar 19 '18 at 03:01

To add to the previous answer I would like to refer to the following answer: https://stackoverflow.com/a/43574427/3751268. I think it covers in details which is the desired way to provide libraries like the jaxb.

In particular for Scala, I add it like this to my libraryDependencies:

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