maven introduces local jar to jar package

Introduce the local jar without building a private server, and package the local jar into the project's run jar

Take the packaging and introduction of hadoop-common-2.7.5.jar as an example

quote

Copy the path where the jar package is located

Open cmd command prompt

Change the path to the directory where the jar is located

cd E:\Xunlei download\hadoop-2.7.5\share\hadoop\common

Add the jar package to the local repository

mvn install:install-file -Dfile=hadoop-common-2.7.5.jar -DgroupId=com.apache.hadoop -DartifactId=hadoop-common -Dversion=2.7.5 -Dpackaging=jar

Parameter Description:

-Dfile: full name of the jar

-DgroupId: Unique ID of custom project collection or project group

-DartifactId: custom project unique identifier

-Dversion: version number

C:\Users\admin\.m2\repository in the C:\Users current user (admin) directory of the computer will generate the corresponding directory structure com\apache\hadoop\hadoop-common\2.7.5

C:\Users\admin\.m2\repository\com\apache\hadoop\hadoop-common\2.7.5 directory is the required jar

My maven local warehouse directory is E:\mavenWarehouse\warehouse

Create a directory structure like com\apache\hadoop\hadoop-common in the configured maven local warehouse directory

E:\mavenWarehouse\warehouse\com\apache\hadoop\hadoop-common

Copy the files and directories in the generated C:\Users\admin\.m2\repository\com\apache\hadoop\hadoop-common directory to the newly created directory E:\mavenWarehouse\warehouse\com\apache\hadoop\hadoop -common

Add dependency references to the project's pom.xml

<dependency>
   <groupId>com.apache.hadoop</groupId>
   <artifactId>hadoop-common</artifactId>
   <version>2.7.5</version>
</dependency>
