thomas@MBP15:Desktop$Maven构建性能优化
减少构建的工程量
只构建指定工程及其相关依赖
bash
# -pl 工程名称
# -am 自动分析相关的依赖工程
mvn clean package -pl gponline-web -am忽略测试
这种忽略测试的方式-Dmaven.test.skip=true，连测试代码都不会进行编译
bash
mvn clean package -pl gponline-web -am -Dmaven.test.skip=true不执行清除
（慎用）可能会导致某些需要清理的类没被清理
bash
mvn package -pl gponline-web -am -Dmaven.test.skip=true并行构建
bash
# 并行构建，充分利用CPU的核心数
mvn -T 1C clean package -pl gponline-web -am -Dmaven.test.skip=true参考
实际构建案例
默认构建速度
bash
time mvn clean package -Dmaven.test.skip=true耗时 2m47.500s
通过并行构建
bash
time mvn -T 1C clean package -Dmaven.test.skip=true耗时 1m41.546s
并行构建，能充分利用CPU的性能。作者6个核心的CPU直接跑满
不执行清理进行构建
bash
time mvn -T 1C package -Dmaven.test.skip=true耗时 1m1.943s
