Yeah we need to update FAQ with the latest changes around this.
it is not M2_OPTS that you need to set but in most cases surefire args as
you need this as part of test runtime not maven runtime.
but --add-opens is the flag you are properly using for this case.
It in most cases replaces need for --add-exports flags
I would also recommend adding -Dsun.reflect.debugModuleAccessChecks=true
flag that should help you with reflection issues.
What is your use case exactly? building a war?
Maybe link to project / pom.xml that has this issue?

We have just upgraded our jdk build to 9-ea+149 which has tightened
up the
accessibility rules. The recommendation seems to be to use the --add-opens
flag to override the rules.
I tried export MAVEN_OPTS="--add-opens java.base/java.util=ALL-UNNAMED"
which made no difference. Our jdk 9 FAQ does not provided any hints either.
Can anyone provide advice on how to resolve the following maven build
error:
