Answer 1

First there is a hint concerning the parameters in the docs

Sets the arguments to be passed to the compiler if fork is set to true. Example:

<compilerArgs>
  <arg>-Xmaxerrs=1000</arg>
  <arg>-XX:PermSize=128m</arg>
</compilerArgs>

which means if you need them for you build you have to do this either via MAVEN_OPTS or you can define them in .mavenrc (linux) or mavenrc_pre.bat (Windows).

Answer 2

From the javac documentation:

-Joption Pass option to the java launcher called by javac. For example, -J-Xms48m sets the startup memory to 48 megabytes.

Based on the above:

<compilerArgs>
  <arg>-J-XX:PermSize=128m</arg>
  <arg>-J-XX:MaxPermSize=256m</arg>
</compilerArgs>

Answer 3

You can just add

export MAVEN_OPTS=-Xmx512m

in your ~/.bash_profile
