Maven set up

[rrodrigueznt]

Hi all,

This is not a XWiki issue, but following the discussion about the Maven
version to standardize on XWiki build I am trying to configure a
developer environment in a MacBook Pro running Mac OS X 10.5.5. Your
help will be really welcome. Thanks!

Mac OS X 10.5.x includes Maven 2.0.6 in its base installation. Thus, mvn
--version gives...

GMXUX-Ricardo-Rodriguez:~ rrodriguez$ mvn --version
Maven version: 2.0.6

I've tried to follow the installation instructions in Maven support site
to install both (or at least one of them) Maven 2.0.9 and/or Maven 2.1.0
M1 but I am falling at setting the correct environment system wide. It
works fine if I export each concerned variable in a given shell, but
this only works for this and only this shell window...

sh-3.2# export M2_HOME=/usr/local/apache-maven/apache-maven-2.0.9
sh-3.2# export M2=/usr/local/apache-maven/apache-maven-2.0.9/bin
sh-3.2# echo $PATH
/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin
sh-3.2# export PATH=$PATH:$M2
sh-3.2# echo $PATH
/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin:/usr/local/apache-maven/apache-maven-2.0.9/bin
sh-3.2# mvn --version
Maven version: 2.0.9
Java version: 1.5.0_13
OS name: "mac os x" version: "10.5.5" arch: "i386" Family: "unix"
sh-3.2# echo $PATH
/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin:/usr/local/apache-maven/apache-maven-2.0.9/bin
sh-3.2#


Please, what method do you use to set M2, M2_HOME and modify PATH to
include M2? Is it possible to set them system wide or at least user
wide? I've tried a number of methods without success.

Thanks for your help,

Ricardo

You can try putting these variables in one of the files (not sure which
are on a mac, I'm on linux now):

/etc/bash/bashrc
/etc/profile
~/.bash_profile
~/.bashrc


You will probably have to reboot to see if it works as a default, or at
least logout/login.

Ricardo,

Just do a wrapper shell script, call it mvn and put it in your path  
befure /usr/bin/mvn.
I put this in the bin of our general utilities, which is put in path  
by my ~/.bash_profile before the others.

Hence i obtain the following which you could easily change:

$ cat `which mvn`
#!/bin/sh

MAVEN_OPTS=-Xmx600m
export MAVEN_OPTS

/project/activemath/javalibs/maven/apache-maven-2.0.9/bin/mvn "$@"


(the directory there is where I installed it... feel free to change it!)

it's running very fine on a MacBook Pro.

It's funny, I hadn't notice that Apple ships maven which is quite  
honourable of them.

Putting concerned variables in ~/.bash_profile did the trick. So,
please, what is the advantage of using a wrapper shell script if I can
pass any and all required variables with ~/.bash_profile to the shell?
Thanks!

My advantage was to change the mvn command deciding on which place to  
use.
You are right however that these methods overlap in the role of  
defining variables!

In a multi-user-setup, the wrapper script is also more important.

Sorry for insist on this but, please, why is the wrapper script more
important in a multiuser setup? .bash_profile is setup in a per user
basis, so could it control Maven settings for each user using a given
box for developing? Thanks!

Ricardo

The wrapper script is somehow better in a multi-user environment because
it is common for all users, so they don't have to modify their own
~/.bash_profile. To sum up:

~/.bash_profile is good because it lets a user define his own settings

A common script is good because it lets all users on a system have the
same settings for maven, which is good if they ALL need the same settings.

Using some global initialization file, like /etc/bash/bashrc has the
same advantages as the common script file, but also has the advantage
that it sets the settings only once, and not every time mvn is executed.

I agree.
Basically upgrading went as follows:
- install and put a wrapper script mvn-2.9
- test, let other tests using that command instead (from time to time)
- when decided to upgrade all replace mvn by a symbolic link to mvn-2.9

There's no performance penalty in setting up a few variables! really  
none.

Not really none, a few nano seconds... Certainly much less that a
hundredth of a second.

compared to a mvn startup?

Thanks both! This step is clear for me now at least in a MacBook Pro
box. Next station: check out the software and try to build it.

I am writing down the steps toward a developing environment in a MacBook
Pro in a XWiki page here...

http://xepecnet.environmentalchange.net/xwiki/bin/view/ICT/DevelopingEnvironmentMacOsX

If you consider it suitable for dev.xwiki.org, let me know where could I
create it and I will move it there. Perhaps as a simple "case study", it
is not worth to move it out of EPEC Network.

Cheers,

Ricardo

Sounds good but why don't you link to the maven book for installing  
maven for example:
http://www.sonatype.com/book/reference/public-book.html ?

This would allow not to repeat the information.

I think a tutorial like this is very worthwhile. I'd personally not  
put any information outside of xwiki and instead provide links since  
otherwise you'll have to explain a lot for all possible situations +  
update if frequently when one of those external tool change.

WDYT?

Note that the difference between set up on Mac OSX, Windows or Linux  
is very slim IMO. For all of them you can (for example) simply unzip  
tomcat and run startup.bat or startup.sh.

Thanks

Simply because I'd not reached this site yet!  Of course this is the
place for detailed instructions and, if anybody find anything missing or
wrong, it must be corrected there. Thanks!

Don't you think it is worth a link to this book about maven in
http://dev.xwiki.org/xwiki/bin/view/Community/Building#HInstallingMaven 
or any other location in this page?

I think that the only merit of this simple tutorial is to create a new
installation workflow focused on creating a developing environment.
Sincerely I think that it won't be frequent that anybody starting
developing in XWiki has not already installed some or all of the
required pieces before reaching this page :-)

This could be possibly truth for experienced people. But, for instance,
to set up a Tomcat daemon in Mac OS X requires some extra work. See...

http://www.malisphoto.com/tips/tomcatonosx.html?#Anchor-JSVC

In Windows, the Tomcat installer does this work for the user. But this
information would be better entered in...

http://platform.xwiki.org/xwiki/bin/view/AdminGuide/InstallationTomcat

Summing up, my draft will remain in our xwiki just for our reference. It
could be worth to add this two links (Maven: The Definitive Guide and
Installing Apache Tomcat 6 on Mac OS X Leopard) in the more suitable place.

WDYT?

Thanks!

Why would you want to do this for developing XWiki code? :)

> http://platform.xwiki.org/xwiki/bin/view/AdminGuide/InstallationTomcat

Sure but it's almost already there I think since we link to http://tomcat.apache.org 
  which should be the place where all information about Tomcat should  
be found.

However feel free to add as many links as you want there, the more the  
merrier.

Great question! I am using Tomcat here for serving a number of
applications. I found it suitable to get it easily running each time I
turn on the box. And at the same time, I am using this method to get
servlets running in other Mac boxes not too busy. I can forget about
users switching off/on boxes, electric power shortcuts,... of course it
will be better to use some reliable servers... any day!! :-)

I think there are a few problems in the environment variables, it should be:


export M2=/usr/local/apache-maven/apache-maven-2.1.0-M1/bin
(note the /bin at the end, in there is the mvn executable)

export PATH=$M2:$PATH
($M2 should be before $PATH, so that mvn is first searched in there, and
then in other directories; this ensures that THIS version of maven is
executed, and not the system-wide one)

export MAVEN_OPTS="-Xmx600m -Xms600m"
I thinx Xms is not a good idea to set to such a large value, as it will
always allocate this much memory, even if it isn't needed.
