After installing and changing the version of mvn via `update-alternatives, the configuration remains unchanged.

Steps

  1. Install new version mvn

    sudo update-alternatives --install /usr/bin/mvn mvn /opt/maven/apache-maven-3.5.0/bin/mvn 100
    
  2. Check alternatives

    $ sudo update-alternatives --config mvn
    There are 2 choices for the alternative mvn (providing /usr/bin/mvn).
    
      Selection    Path                                   Priority   Status
    ------------------------------------------------------------

      1            /opt/maven/apache-maven-3.3.9/bin/mvn   100       manual mode
      2            /opt/maven/apache-maven-3.5.0/bin/mvn   10        manual mode
    
    Press enter to keep the current choice[*], or type selection number: 2

  3. Change alternative to new one

    $ sudo update-alternatives --config mvn
    There are 2 choices for the alternative mvn (providing /usr/bin/mvn).
    
      Selection    Path                                   Priority   Status
    ------------------------------------------------------------
      0            /opt/maven/apache-maven-3.3.9/bin/mvn   100       auto mode
      1            /opt/maven/apache-maven-3.3.9/bin/mvn   100       manual mode
    * 2            /opt/maven/apache-maven-3.5.0/bin/mvn   10        manual mode
    
    Press enter to keep the current choice[*], or type selection number: 2 
    
  4. Check mvn version

    $ mvn --version
    Apache Maven 3.3.9 (bb52d8502b132ec0a5a3f4c09453c07478323dc5; 2015-11-10T17:41:47+01:00)
    Maven home: /opt/maven/apache-maven-3.3.9
    Java version: 1.8.0_111, vendor: Oracle Corporation
    Java home: /opt/java/jdk1.8.0_111/jre
    Default locale: ca_ES, platform encoding: UTF-8
    OS name: "linux", version: "3.13.0-116-generic", arch: "amd64", family: "unix"
    

type command output:

$ type -a mvn
mvn is /opt/maven/apache-maven-3.3.9/bin/mvn
mvn is /usr/bin/mvn

  • I had modified the ~/.profile PATH variable, so the only thing I had to do is to comment out the line and log in again.

    .profile

    ...
    #export PATH=/opt/maven/apache-maven-3.3.9/bin:$PATH
    ...
