Can not change update-alternatives mvn

Ubuntu 14.04

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
   ------------------------------------------------------------
   * 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
   update-alternatives: using /opt/maven/apache-maven-3.5.0/bin/mvn to provide /usr/bin/mvn (mvn) in manual mode
   

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

Solution 1:

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
