Maven: updating version on Mac

While trying building with Maven I was getting errors related to version number (below 3.1) 

mvn install
Error: Could not find or load main class org.codehaus.plexus.classworlds.launcher.Launcher

To update my maven I have to do the following sequence of steps.

$ mvn -version

Apache Maven 3.0.5 (r01de14724cdef164cd33c7c8c2fe155faf9602da; 2013-02-19 07:51:28-0600)

I had to uninstall the older version 3.0

$ brew uninstall maven30

Uninstalling /usr/local/Cellar/maven30/3.0.5...

Trying to install newest I noticed that I tried it before, but it was not linked

$ brew install maven

Warning: maven-3.2.3 already installed, it's just not linked

The easiest way to fix that is to uninstall and install again:

$ brew uninstall maven

Uninstalling /usr/local/Cellar/maven/3.2.3...
$ brew install maven

==> Downloading downloaded: /Library/Caches/Homebrew/maven-3.2.3.tar.gz
��  /usr/local/Cellar/maven/3.2.3: 76 files, 8.0M, built in 3 seconds
uki@ CNH_PROD $ mvn -version
Apache Maven 3.2.3

Groovy on Android

Android developers are already using Groovy in many places AROUND Android, for example in Gradle build scripts. Now the dream of using Groovy as primary language for Android is a little closer to realization! See what is cooking.

Installing Maven

After few years of not needing it, I came back to Maven, reason being that I cannot use Gradle for reasons beyond my control and Ant does not describe complex projects structures required.

Bash: GIT repetitive tasks

I have too many GIT repos to remember that I need to keep updated, to do that I have a script that updates what I need.

Mac Daemons that hunt us

Sometimes you get annoyed by garbage other companies are trying to stuff on your computer. Motorola is one of these companies. When I connect my test DROID device the annoying popups are opened. 

This is not a conclusive solution, but a start of the longer article on the unwanted Mac Daemons that suck up your patience and CPU power.

Removing Launch services

$ launchctl list | grep moto
- 0 com.motorola.motohelperUpdater
32594 - com.motorola.motohelper
- 0 com.motorola.MDMUpdaterPlist
$ launchctl remove com.motorola.motohelper

$ launchctl remove com.motorola.motohelperUpdater

Removing unwanted Application

cd /Library/Application\ Support/
$ ls | grep Moto

Motorola Mobility
uki@ Application Support $ sudo rm -r MotoCast

uki@ Application Support $ sudo rm -r Motorola\ Mobility/

List of legitimate Services:

  • PTPCamera - part of the Image Capture software that MacOS uses

Got Droid? - My Android (test) devices

While cleaning my office I decided to make an inventory of my Android devices.

Please note that it is NOT worth testing on anything less than API 8 Android 2.2 Froyo as it is less than 0.7% of the market share,  so it is OK to use support library v7 in all apps you are running. 
I keep my Google ION for "sentimental reasons only.
