java - Maven 中的默认生命周期是什么

Question

我正在尝试学习 Maven，并通过 Maven docs 中的以下声明进行学习

There are three built-in build lifecycles: default, clean and site. The default lifecycle handles your project deployment, the clean lifecycle handles project cleaning, while the site lifecycle handles the creation of your project's site documentation.

还有另一条声明说:

default (or build):This is used to build the application.

我能够成功运行命令 mvn clean 和 mvn site。但是当我运行以下命令时出现异常:

命令:

mvn default & mvn build

错误详情:

[WARNING]

你还没有读完:

To do all those, you only need to call the last build phase to be executed, in this case, deploy:

mvn deploy

事实上，默认生命周期包含阶段(按此顺序):

validate - validate the project is correct and all necessary information is available
compile - compile the source code of the project
test - test the compiled source code using a suitable unit testing framework. These tests should not require the code be packaged or deployed
package - take the compiled code and package it in its distributable format, such as a JAR.
integration-test - process and deploy the package if necessary into an environment where integration tests can be run
verify - run any checks to verify the package is valid and meets quality criteria
install - install the package into the local repository, for use as a dependency in other projects locally
deploy - done in an integration or release environment, copies the final package to the remote repository for sharing with other developers and projects.

并且您需要在命令行中指定要执行的最后一步，它将执行这一步和这一步之前的所有步骤。例如，如果您这样做:

mvn install

它将执行:验证、编译、测试、打包、集成测试、验证和安装(以及其他一些阶段，请参阅 complete list)。
