Try compile the project first. Run your command as before but slightly modified:
mvn -e compile exec:java
Justification: Of course I don't have your sources and cannot be 100% sure but I have the very same error if I execute without compiling first:
c:\standalone-jpa>mvn exec:java -Dexec.mainClass=tomczak.jpa.JpaTest

Then, you should run your command again:
mvn exec:java -Dexec.mainClass="your.Class"
回答2:
For my case, I had the wrong npm version installed. I needed the 7.6 for my dependencies but I had the 3.6.
I removed and installed npm to the newest version:
sudo apt-get remove npm && sudo apt-get autoremove
curl -sL https://deb.nodesource.com/setup_7.x | sudo -E bash -
sudo apt-get install -y nodejs
sudo apt-get install -y build-essential
curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.33.1/install.sh | bash
source ~/.bashrc
nvm install 7.6
nvm use 7
