MAVEN_OPTS environment variable: This variable contains parameters used to start up the JVM running Maven and can be used to supply additional options to it. E.g. JVM memory settings could be defined with the value -Xms256m -Xmx512m.

So no need anymore for MAVEN_OPTS, .mavenrc files. So for example if you put the following JVM options into the $ {maven.projectBasedir}/.mvn/jvm.config file You don’t need to use these options in MAVEN_OPTS or switch between different configurations.
Keeping this in consideration, MAVEN_OPTS environment variable: This variable contains parameters used to start up the JVM running Maven and can be used to supply additional options to globally to Maven.
