java - Maven clean install 等于 mvn clean 和 mvn install 之后？

Question

我有多模块 Maven 项目。发现：

mvn clean - 需要 3 分钟后

mvn install - 需要 18 分钟。

所以我想 mvn clean install 应该需要 21 分钟，但需要将近 30 分钟！也一样：

mvn clean install

和

mvn clean
mvn install

? 谢谢。

Answer 1

AFAIK，是的，虽然我对启动/解决/等有点惊讶。需要那么多时间。

诸如操作系统缓存、JVM 启动/优化/等等之类的东西都会在差异中发挥作用。

Answer 2

举个例子

framework
    framework-utils
 foundation
    foundation-model
    foundation-api
    foundation-core

 The call order of my modules:
 1. mvn clean / mvn install:   [clean] framework-utils [clean] 
 foundation-model [clean] foundation-api [clean] foundation-core 
 [install] framework-utils [install] foundation-model [install] 
 foundation-api [install] foundation-core
 2. mvn clean install: [clean] framework-utils [install] 
 framework-utils [clean] foundation-model [install] foundation-model 
 [clean] foundation-api [install] foundation-api [clean] 
 foundation-core [install] foundation-core
