Premise: java environment has been configured
for java maven project management
A, maven mounted mac
1, first of all, maven Download http://maven.apache.org/download.cgi
Click into the latest version of maven, but later we found the latest version there are some problems, so I actually downloaded the old version 3.6.1
Click on the bottom of the "archive" hyperlink to download the old version
2, after downloading unzip the folder you want to put into place the path below, such as /Users/zwf/apache-maven-3.6.1
In this case then need to change the .bash_profile, there are two methods, one is to use a direct instruction to save changes in the terminal, the terminal to open a file is saved
The first:
① input vim ~ / .bash_profile
② input i edit
export M2_HOME="/Users/zwf/apache-maven-3.6.1"
export PATH="$M2_HOME/bin:$PATH"
③ Input: wq save (: w save file,: wq to save and exit command)
④ configuration files take effect source ~ / .bash_profile
The second (which is actually used)
① Input open ~ / .bash_profile
② modified to automatically open the file in
export M2_HOME="/Users/zwf/apache-maven-3.6.1"
export PATH="$M2_HOME/bin:$PATH"
After you click the Save button
③ profile commencement source ~ / .bash_profile
After the completion of changes to the configuration file, enter in a terminal mvn -v can see if the installation was successful and the installation path
3, setting.xml conf file in the folder maven
If you want to change the file, you can directly replace the cover
Two, intelliJ IDEA configuration of the maven
Disposed in preferences-maven
maven home dictionary :( is above /Users/zwf/apache-maven-3.6.1, can be overridden)
user setting file: (setting.xml path, to check override coverage)
local reponsitory: local repository path, from setting.xml in the configuration, generally do not cover
<! - path to the local warehouse. The default value is $ {user.home} / m2 / repository ->
<localRepository>usr/local/maven</localRepository>
Configured to save the ok
Third, a problem encountered
After configuring failed to import from git, but also can not download resources from maven
提示unable to import maven project:see logs for details
Let go View log View log, click on the help-Show Log in Finder

......
The reason: Maven3.6.2 version compatibility issues.
Solution: re-download an earlier version Maven3.6.1 and below can be resolved smoothly.
