Workaround: Modify the MAVEN configuration file

[Root@chen_liang5 bin]# pwd
/home/hadoop/downloads/apache-maven-3.3.9/bin
[Root@chen_liang5 bin]# Vim MVN

Add the following configuration: maven_opts= "$MAVEN _opts-xms512m-xmx512m-xx:maxpermsize=256m-xx:reservedcodecachesize=64m"

Recompile succeeded
