Bug#740955: <no subject>

[Potter, Tim (Cloud Services)]

This is bugging me as well, and I've figured out the root cause.  The maven2 package runs update-alternatives with a priority of 200, and maven (3) with a priority of 150.  If you install maven2 and maven at the same time, you will always get maven2.  Since maven2 is a dependency for maven-debian-helper this will nearly always be the case.

# apt-get install –y maven maven2
# mvn -v
Apache Maven 2.2.1 (rdebian-15)
Java version: 1.7.0_65
Java home: /usr/lib/jvm/java-7-openjdk-amd64/jre
Default locale: en_US, platform encoding: ANSI_X3.4-1968
OS name: "linux" version: "3.15.3-tinycore64" arch: "amd64" Family: "unix"
# update-alternatives --config mvn
There are 2 choices for the alternative mvn (providing /usr/bin/mvn).

  Selection    Path                       Priority   Status
------------------------------------------------------------
* 0            /usr/share/maven2/bin/mvn   200       auto mode
  1            /usr/share/maven/bin/mvn    150       manual mode
  2            /usr/share/maven2/bin/mvn   200       manual mode

A more sensible default might be setting the priority of maven (3) to 250 so it becomes the default, but this may have some unexpected side effects.
