maven内存不足：Unexpected error occurred: Not enough memory to allocate buffers for rehashing Java heap

• 具体错误

[ERROR] Failed to execute goal org.teavm:teavm-maven-plugin:0.6.0-SNAPSHOT:compile (wasm-client) on project teavm-samples-benchmark: Unexpected error occurred: Not enough memory to allocate buffers for rehashing: 0 -> 8,192: Java heap space -> [Help 1]

• 找到mvn的位置

whereis mvn

• 编辑mvn

找到MAVEN_OPTS的定义位置，在之后加入一句：

MAVEN_OPTS="`concat_lines "$MAVEN_PROJECTBASEDIR/.mvn/jvm.config"` $MAVEN_OPTS"
# 增加这一句，加大内存，充分利用。
MAVEN_OPTS="${MAVEN_OPTS} -Xmx16384m"

windows同理。
