Maven Java heap space OutOfMemoryError 2018-05-31 22:21

When I run mvn clean install -DskipTests to build my project I got an error message. The content of message is like following.

[ERROR] Java heap space -> [Help 1]
[ERROR] To see the full stack trace of the errors, re-run Maven with the -e switch.
[ERROR] Re-run Maven using the -X switch to enable full debug logging.
[ERROR] For more information about the errors and possible solutions, please read the following articles:
[ERROR] [Help 1]

This error means there is no enough heap space for maven to build project. To solve this problem we need to increase the size of memory by adding MAVEN_OPTS. The introduction of maven configuration is here

I run MAVEN_OPTS="-Xmx500m" mvn clean install -DskipTests in terminal and the error message disappears.
