Configurable repository. Default Value: user directory \. m2 \ Repository

-- It can be configured as <localrepository >$ {env. m2_home}/Repository </localrepository>

 

Run MVN help: System

At this time, MAVEN will download a lot of things from the remote warehouse. It's okay to let it download. It will be downloaded sooner or later.

 

(By default ,~ The/. m2 directory contains no other directories and files except the repository. However, most Maven users need to copy the m2_home/CONF/settings. xml file ~ /. M2/settings. xml. This is a best practice)

Iii. Problems during installation:
If you directly install maven2 online, the dependency plug-in cannot be found and cannot be installed. You must install the GEF plug-in before installing the m2eclipse-core plug-in, but installing the m2eclipse-extras plug-in is dependent on the subclipse plug-in. Therefore, the correct installation sequence of the three plug-ins is: GEF plug-ins, subclipse plug-ins, and m2eclipse plug-ins.
M2eclipse-core plug-in -- Dependency --> GEF plug-in
M2eclipse-extras plugin -- Dependency --> subclipse plugin

You may need to install the GEF plug-in and SVN plug-in first.

1.4.1 install the GEF plug-in first

When the maven plug-in is installed, it will be attached to this plug-in and installed in eclipse-> help-> install new software,

GEF

Http://download.eclipse.org/tools/gef/updates/interim/

1.4.2 install SVN plug-in

Install in eclipse-> help-> install new software, site: http://subclipse.tigris.org/_1.6.x
