The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn how to import the jar package to the local warehouse by maven.

Scene

In many cases, the jar package is downloaded remotely through maven, but the download fails or is very slow due to network speed or warehouse address problems. Another situation is that some of the three-party jar packages we use are not available in the central warehouse, such as some open source compiled jar packages.

In scenarios like this, we often have the need to install the jar package obtained by other means to the local maven repository, and then specify it in pom.xml and then use it directly.

Download commonly used jar packages

1. Copy from other projects, the projects we usually write or download others may have some commonly used jar packages, look at these places first.

View the location of the local warehouse

My maven warehouse location is d:\ mavenfiles\ repo directory. After maven installation, the default warehouse location is under the .m2 directory under the C disk user directory. I changed it to D disk. As for how to modify it, I will not repeat it here. Also pay attention to the configuration of maven in IDE such as Myeclipse.

Install to local warehouse

For example, I saved the downloaded jar package in the local C:\ temp directory, where I opened the command line to install it.

C:\ temp > mvn install:install-file-Dfile=log4j-1.2.16.jar-DgroupId=log4j-DartifactId=log4j-Dversion=1.2.16-Dpackaging=jar [INFO] Scanning for projects...
