Answer 1

There is no way using the commandline. But you could copy the mvn.cmd / mvn.sh to mvnhp.cmd and change the line

%MAVEN_JAVA_EXE% %JVM_CONFIG_MAVEN_PROPS% %MAVEN_OPTS% %MAVEN_DEBUG_OPTS% -classpath %CLASSWORLDS_JAR% "-Dclassworlds.conf=%M2_HOME%\bin\m2.conf" "-Dmaven.home=%M2_HOME%" "-Dmaven.multiModuleProjectDirectory=%MAVEN_PROJECTBASEDIR%" %CLASSWORLDS_LAUNCHER% %MAVEN_CMD_LINE_ARGS%

To

%MAVEN_JAVA_EXE% -Xmx1024m %JVM_CONFIG_MAVEN_PROPS% %MAVEN_OPTS% %MAVEN_DEBUG_OPTS% -classpath %CLASSWORLDS_JAR% "-Dclassworlds.conf=%M2_HOME%\bin\m2.conf" "-Dmaven.home=%M2_HOME%" "-Dmaven.multiModuleProjectDirectory=%MAVEN_PROJECTBASEDIR%" %CLASSWORLDS_LAUNCHER% %MAVEN_CMD_LINE_ARGS%
