Answer 1

I had the same issue while attempting to generate java classes from xsd file.

My installed Eclipse is: Eclipse Java EE IDE for Web Developers Version: Oxygen.3a Release (4.7.3a)

Build id: 20180405-1200

I solved it changing the workspace default JRE from JRE to JDK in Project Properties / Java Build Path / Libraries

you may download JAXB Eclipse Plug-In

jaxb eclipse plugin

Answer 3

After a lot of research here is what I have done to fix the issue. Windows> Preferences> Java> InstalledJREs...make sure to point your jre to the jdk directory. I was pointing to JRE and as soon as I changed it to JDK, it started working. Hope this will help you guys.

Answer 4

The above methods may work, but actually the options comes from a plugin called Web Tools Platform which comes along with Eclipse IDE for Java EE Developers.

Don't worry about reinstalling eclipse or try out other methods. No matter what eclipse you use simply install this plugin by following the below procedure. You will get the "JAXB Classes" Option on click of "Generate" button.

Help --> Install New Software --> Add

Name : Web Tools Platform
Location : http://download.eclipse.org/webtools/repository/helios

Hint : In case if you are using a different version replace helios with your eclipse version name. I used it as luna. So the path looks like http://download.eclipse.org/webtools/repository/luna

And restart eclipse. Now you will have that option.
