Java Mavn 2. Precautions

MAVEN Specifies the warehouse location, specifying the remote warehouse

1. Specify the warehouse location (warehouse refers to the unified management location of the jar package required by the Java project)

Maven Location: D:\apache-maven-3.0.2

Default Warehouse Location C:\Users\Administrator\.m2\repository

Pre-specified location: C:\Program files\java\maven\repository

Open the "conf" file in the Maven location and open "Settings.xml" in the text editor to find

<settings xmlns= "http://maven.apache.org/SETTINGS/1.0.0"
Xmlns:xsi= "Http://www.w3.org/2001/XMLSchema-instance"
xsi:schemalocation= "http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd" >

Join in the next line above
<localrepository>c:\program files\java\maven\repository</localrepository>

When set, assign the current file (settings.xml) to "C:\Program files\java\maven\"

Added from Windows environment variables: m2_repo=C:\Program files\java\maven\repository, adding this variable to the PATH variable.

Eclipse settings

2. Specify a remote repository

In C:\Program files\java\maven\, open the settings.xml file with the editor

Add to

<mirrors>    <mirror>      <id>local-nexus</id>      <name>maven Repository switchboard</name>      <mirrorOf>*</mirrorOf>      <url>http://xxx.xxx.xxx.xxx:xxxx/ nexus/content/groups/public/</url>    </mirror></mirrors>
