Hi Mike,
I had tried MAVEN_OPTS="--add-opens java.base/java.util=ALL-UNNAMED --add-opens
java.base/java.lang.reflect=ALL-UNNAMED --add-opens java.base/java.text=ALL-UNNAMED
--add-opens java.desktop/java.awt.font=ALL-UNNAMED" and it works.

Subject: [wildfly-dev] jdk 9 reflection problem
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:
[WARNING] Error injecting: org.apache.maven.plugins.war.WarMojo
