Best Guide for compile with maven!

[EzEraL]

Welcome to "How to compile with maven" guide
Version:v2
Release:12/8/08
Credits:Noctarious-Hanwik

Ok lets start.Long time ago L2jfree change from ant to maven comprehesive tool.Many users try to manage maven but couldnt succeed
So in this guide i will try you to learn you the most easy way to get and compile latest l2jfree gameserver(core) and of course to get and compile its forks like l2emu and l2jumbrella

Ok this is the part of gameserver.First download the TortoiseSvn client.However because l2jfree has no support for TortoiseSvn 1.5++ you must download version 1.4.6

Download link:SourceForge.Select 1.4.6 not another version....

Install it.Then go to a directory that you prefer to have your workspace,for example my domuments.Create a folder and name it as the pack that you want to checkout for example l2jfree.Go inside that folder and press the right click of your mouse.You will see an option "Svn Checkout".Press it.Then add the svn of the project you want(l2jfree,l2emu,l2jumbrella) and press ok.

Wait until it finish.When it finish go and download maven
Download link:Maven

Extract maven to an empty folder for example in C://
So its directory will be C://

Ok now go to your project checkout folder that you create earlier.You will see5 folders
1)archive
2)Trunk
3)Tags
4)Branches
5)Release

In release folder there are the stable version sources and in trunk the current unstable sources.Lets say that you want to build a stable version
Go to release folder and open the version you want.For example 1.1.4.Inside it you will see a pom.xml file.Right click on it and press "open with"and then "Choose Default program".A menu will appear.Press "Browse"and go windows/system32 and select the cmd.exe file(cmd).Then open the pom.xml file with cmd.

Finally "write your path to maven/bin/mvn assembly:assembly -Dmaven.test.skip=true" with out the ""
So if your path is C:// you will write
C://maven/bin/mvn assembly:assembly -Dmaven.test.skip=true
And thats all.You wait until it finish and you compile the gameserver.Now your server is located in release/the version you choose to compile/target

Note:Soon i will share how to compile with maven under ubuntu and other linux distros

L2jfree's guide is halfway correct,but it does not explain everything step by step that is why it is outdated.
Based on l2jfree's guide,the following is a GOOD guide which will 101% help you compile :

Download Maven

Maven - Download Maven 2.0.7

extract it on C:/ (or D:/ whatever disk you got) and name the folder maven.(Make sure the bin folder is located on : C:/maven/bin/ and you're ok.

Run Maven

open cmd (Start -> run -> cmd)
go to your l2jfree directory (lets say you created a workspace named Server,then type cd server , cd (the project's name,assuming you have already checked out from your repository)
Now type "cd .." until it says only C:/ or D:/ etc etc.Then "cd maven" "cd bin" (without the "") and then "mvn eclipse:eclipse"

Eclipse Settings
now start eclipse
open the preferences ( window/preferences)
open classpaths (java/Build Path/Classpath Variables)
click "NEW"
Name: M2_REPO
Path: locate your .m2 directory /home/.m2/repository NOTE: home is C:\Documents and Settings\YOURUSERNAME under windows
Now refresh your workspace and youre set

Ready to compile?
Open cmd again (I assume you are located at C:/Documents and Settings/YourUserName) and type
"cd Server"
"cd trunk" (again,this is your checked out project's name)
"cd l2_loginserver_il" (it can be l2_gameserver_il or l2_datapack_il)(and again without the "" 's)
then
"C:/maven/bin/mvn"
and it will compile.

This is for L2jFree compiling.


I got this error in my console (windows command line)


ERROR: JAVA_HOME not found in your environment.
Please set the JAVA_HOME variable in your environment to match the
location of your Java installation


You just have to set JAVA_HOME in your environment variable.
workspace => right click => properties => advanced => environment variable
Add new variable JAVA_HOME that target your installation path of JDK (ant not your JRE)

IF THE ABOVE STILL DOES NOT WORK DO THE FOLLOWING!
(Start -> right click "my computer" and go to properties -> advanced -> Envirronment Variables -> on the bottom box make a new entry with the following data
Name : JAVA_HOME
Value : C:/Program Files/Java/jdk1.6.0_02 )
(well that is where my jdk is located)

I do not believe you will get ANY errors...

[Droppo]

Mmmm looks like a nice guide... just needs alot of pics and it's done...

Good one EzEraL...

Droppo.-

[EzEraL]

Thx droppo but why pictures all of us that compile with maven we didnt have pics.So why?I think is very easy

And for the best guide i say it for fun.xD

And thx Teufelskerl i edit the post

[Droppo]

Yeah... could be... but I will be expecting from now on, the first credits stealer that will make an exact copy of this, remove the credits, add some pics and call it his guide...
I have seen that happen long time ago and not just once...

Droppo.-

wtf is this ? :scratch:

Yeah i have the same problem any help?

[Droppo]

Lol! You're trying to compile "2j-test-tools"??? you gotta be kidding me... That doesn't needs to be compiled... just gameserver, loginserver and datapack (wich uses ant) the rest like mmocore and other shits are dinamically added to the project you want to compile

Droppo.-

[EzEraL]

I add in guide images.I hope to help more now.Also because i buy second hd i install eclipse and ect here so i remove maven for some tests and i reinstall it.I follow my guide to see if it is correct and works like a charm

[EzEraL]

Are you install maven plugin in eclipse?And you install maven correct?Be more specific

[andycris1993]

Yes I instaled it in eclipse and I did like in your guide!
Maybe it will work whit the old build.xml method.
