maven clean install等于mvn clean并在mvn安装后？

Question

我有多模块maven项目。发现：

mvn clean - 需要3分钟 之后

mvn install - 需要18分钟。

所以我认为mvn clean install需要21分钟，但需要30分钟！ 同样如此：

mvn clean install

和

mvn clean
mvn install

？ 感谢。

Answer 1

AFAIK，是的，虽然我对启动/解决/等有点惊讶。 那很长时间。

OS缓存，JVM启动/优化等等等都会在差异中发挥作用。

Answer 2

让我们举个例子

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
