Cannot build Eclipse RCP project with Tycho and Java 9

Question

My Eclipse RCP Maven project builds fine with Java 8, but fails with Java 9:

Any ideas how to resolve this error? I tried to set MAVEN_OPTS=--add-modules java.se.ee but this didn't help.

My JDK version is 9-ea+175.

UPDATE

I upgraded tycho version from 0.25.0 to 1.0.0. Now the build starts fine but fails later with hundreds of errors like:

... Compilation failure:
The type java.lang.Object cannot be resolved. It is indirectly referenced from required .class files

Answer 1

This can be because of the few plugins/bundles which were not available during the Runtime/debug. Please visit your project "Run Configurations.." and go to Plug-ins tab. Enable the below plug-ins

 1. org.eclipse.equinox.ds
 2. org.eclipse.team.core
 3. org.eclipse.ui.trace
 4. org.eclipse.equinox.util
 5. org.eclipse.equinox.common 

and then you click on "Add Required Plug-ins" button present in the right side and click Apply and Run the application again.

Similar kind of bug has been already reported in eclipse Eclipse Bug. You can refer this also.
