如何使用命令行在 maven 中执行 2 个或多个 java 文件？

Question

I am new in maven and I would like to execute 2 java file at the same time. I read a few posts in StackOverflow and because I do have limited knowledge with maven, I couldn't understand how to do it. I attached my pom.xml file here and the command line that I am using in mac terminal is:

mvn compile exec:java -Dexec.mainClass="org.parallel.ParseThread1"

I have another file named: ParseThread2 and every time I am running them separately like this:

mvn compile exec:java -Dexec.mainClass="org.parallel.ParseThread1"

mvn compile exec:java -Dexec.mainClass="org.parallel.ParseThread2"

I want to know if maven is capable of executing both at the same time.

Few posts that i read was:

My pom.xml file is:
