Different Maven versions + Custom configuration

[MitchK]

Hi!

We would like to be able to choose the Maven version in Java builds for different projects (due to corporate requirements). This might be also great for the public Travis CI offering.

Currently, our developers download and install a custom Maven version on the fly. As we are internal service providers and would like to offer Travis as a tool that takes care of such things, it would be awesome being able to specify the Maven version.

Furthermore, we have a custom settings.xml that we currently provide with our machine images. I would be also great to provide a custom settings file for the builds.

All this could be done by implementing a maven key in the `.travis.yml``:

maven: 
  version: 3.0.0
  config: settings.xml
  ...

That would be good especially for maven plugins matrix build, so +1 also for me.

Meanwhile did someone solved that differently?

Workaround
before_install:

• wget https://archive.apache.org/dist/maven/maven-3/3.3.9/binaries/apache-maven-3.3.9-bin.zip
• unzip -qq apache-maven-3.3.9-bin.zip
• export M2_HOME=$PWD/apache-maven-3.3.9
• export PATH=$M2_HOME/bin:$PATH

I personnally switched to docker using the following (see it in action in jgitver-maven-plugin for example)

language: bash

sudo: required

services:
  - docker

script:
  - docker run --rm -v $(pwd):/root/sources -w /root/sources maven:3.3.9-jdk-8 mvn -Prun-its clean install

after_failure:
  - find target/it -name *.log -exec echo {} \; -exec cat {} \;

branches:
    except:
        - gh-pages

@TuomasMatilainen Thanks for the suggestion with before_install!!
That is currently still working.

Note my travis.yml looks like similar (I know it might not be the most compact config but does exactly what I want to test):

language: java
sudo: false
dist: trusty
jdk:
  - oraclejdk9
  - oraclejdk8
  - openjdk7

matrix:
  include:
  - jdk: openjdk7
    env: CUSTOM_MVN_VERION="3.0"
  - jdk: openjdk7
    env: CUSTOM_MVN_VERION="3.1.1"
  - jdk: openjdk7
    env: CUSTOM_MVN_VERION="3.2.5"
  - jdk: openjdk7
    env: CUSTOM_MVN_VERION="3.3.9"
  - jdk: oraclejdk9
    env: CUSTOM_MVN_VERION="3.5.0"

install:
  - if [[ -n "${CUSTOM_MVN_VERION}" ]]; then
      echo "Download Maven ${CUSTOM_MVN_VERION}....";
      if [[ "${CUSTOM_MVN_VERION}" == "3.0" ]]; then
        wget https://archive.apache.org/dist/maven/binaries/apache-maven-3.0-bin.zip || travis_terminate 1;
      else
        wget https://archive.apache.org/dist/maven/maven-3/${CUSTOM_MVN_VERION}/binaries/apache-maven-${CUSTOM_MVN_VERION}-bin.zip || travis_terminate 1;
      fi;
      unzip -qq apache-maven-${CUSTOM_MVN_VERION}-bin.zip || travis_terminate 1;
      export M2_HOME=$PWD/apache-maven-${CUSTOM_MVN_VERION};
      export PATH=$M2_HOME/bin:$PATH;
      mvn -version;
    fi

feel free to use it for whatever project / license
