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

问题

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

回答1:

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.

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")

You can add dependencies in maven

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