如何使用maven工具加快构建过程
我使用maven作为构建工具。 现在我正在做如下的构建
Right click on the project - >maven clean.
在这之后
Right click on the project - >maven install
我需要3分钟。有什么方法可以加快我的进程
我已经看到了这个 。 但我不明白这一点。 任何人都可以解雇我吗？
提前致谢…

如果你在一个项目中使用多个maven模块，这可能对你有用：我主要是通过控制台使用Maven，所以我在eclipse下没有这方面的经验，但是从Maven 3开始，Maven支持并行构建。 这个function开箱即用，但它的成功在很大程度上取决于您使用的插件，因为第三方插件可能无法以这种方式工作。
要激活并行构建，请使用-T参数启动maven：
mvn clean install -T 2
用2个线程构建。
mvn clean install -T 2C
每个CPU使用2个线程构建。
Maven将确定构建顺序并尽可能并行化。
遗憾的是，如果您的项目模块结构非常线性，即项目A – >项目B – >项目C，这对您没有任何好处。
如果您的项目有测试用例，您可以通过以下命令跳过测试。
mvn clean install -Dmaven.test.skip=true
只是尽量避免每次在脱机模式下下载Execute Maven以避免每次运行构建时下载依赖项。
如果使用命令行，则可以使用-o作为参数。
