Hi,
What branch and JDK version are you using? Is should not be necessary to
configure
`--add-opens` by hand. In the past, I ran into problems like this, when I was
moving back
and forth between JDK versions, and sometimes the IDE can stuck in a confused
state.
In general, I would suggest to invalidate caches ('File -> Invalidatre
Caches...'),
mark everything there except the embedded browser cleanup. To start from a
clean slate,
you can also close IntelliJ, and remove the `.idea` and all `*.iml` files from
the cloned
repository. Assuming `release-2.0` or `master` branch, for development IMO
JDK17 should
be used. So before anything, I tend to build the project from the terminal with
JDK17 +
Maven 3.8.6 via `mvn clean install -DskipTests -Dfast -T1`, this will
definitely succeed.
>From this point, when you reopen the project in IntelliJ, make sure the

to JDK17. In the general settings, under 'Build, Execution, Deployment ->
Compiler ->
Java Compiler' you can check the applied 'Project bytecode version' and
'Per-module
bytecode version', but by default those should match the project SDK.
+1 hint, sometimes it can be confusing why IntelliJ cannot build Scala modules.
In my
experience most of the times, the cause of that is the Scala compiler is
configured for
a different JDK version than the project. That can be checked under
'Build, Execution, Deployment -> Compiler -> Scala Compiler -> Scala Compile
Server', and
making sure the JDK configured there matches with the one configured at project
SDK.
Cheers,
Ferenc
