How to manually install jar packages into a warehouse in Maven and problems

As we all know, as long as we configure in the Pom.xml file, maven will automatically download the jar package to the local repository, so if we write a jar ourselves, then we cannot refer to this package by configuration, we need to manually install the package into the warehouse.

We use the command mvn install:install-file-dfile=your-jar-file-path-dgroupid=com.your.group-dartifactid=your-artifactid -dversion=x.x-dpackaging=jar installing the jar in Doc

-dfile: Indicates where the jar package needs to be installed

-dgroupid: Indicates GroupID

-dartifactid: Indicates artifactid

-dversion: Specify version

The above three parameters corresponding to the three parameters in the Pom file configuration, the corresponding, the Pom file is as follows:

<dependency> <groupId>alipay</groupId> <artifactId>alipay</artifactId> <version >1.0.0</version></dependency>

When we execute this command, remember to be in the same path as the Pom file, otherwise the following error will be reported (cannot find the pom file):

After the installation we open the local repository and we will see that we have created our own file path, and then we add the dependency in the Pom file OK.
