mvn java:exec with increased memory
I use "mvn exec:java" to run my program:
mvn exec:java -Dexec.mainClass="..." -Dexec.args="..."
I didn't find to change the maximum memory allocation to the JVM.
I tried -Dexec.commandlineArgs="..." but that didn't work...
<commandlineArgs> (or -Dexec.args when given in the CLI) is for specifying the arguments given to the program, not the JVM.
As exec:java executes a Java program in the same VM as the Maven one, just change the Maven JVM memory settings (so MAVEN_OPTS) to get more memory for your exec:java command.
You can use exec:exec to run java in separate process. Then you can specify any arguments (including -Xmx). See https://stackoverflow.com/a/25442840/658606 for more details and for an example .
