==First Steps==
<ol>
<li> First of all open the view called Package Explorer.</li>
<li> "New Project..."</li>
<li> "CVS" -> "Project from CVS" </li>
<li> Get stendhal from CVS. (Connection type: pserver, User: anonymous, Password - leave blank, Host:arianne.cvs.sourceforge.net, Repository: /cvsroot/arianne)</li>
<pre>
file-> new -> project -> project-> from cvs
click next


This guide describes how to setup a development environment in Eclipse for Stendhal.
check "create new repository"
click next


== Get Java ==
host : arianne.cvs.sourceforge.net
repository path : /cvsroot/arianne
user : anonymous
connection Type: pserver
click next


* If you can play Stendhal, you already have Java and can skip this step.
check "use an existing module"
* If you do not have java installed, please download it https://java.com<br> (if you are on Linux, use your packet manager)
click directory: stendhal
click next


== Get Node.js ==
checkout as a project configured using the new project wizard
click next


* https://nodejs.org (optional: for building & using web client)
click finish


== Get Eclipse==
select a wizard: java project
project Name: stendhal ( or whatever you like to call it )
make sure in jre a java version 1.5 or higher is selected
click finish
</pre>
<li> Make sure that the marauroa.ini (server.ini, for Stendhal version 0.63 or above) is in your stendhal project folder - '''only needed if you will be running the server or junit tests'''.</li>
<li> Right click on your project folder and select "Properties" in the context menu.</li>
<li> Then select "Java Build Path" on the left side of the dialog box.</li>
<li> Now remove all existing folders from source path and add the two source folders 'src' and 'tests' by clicking on the "Add Folder..." button</li>
<pre>
source folder #1:
stendhal/src
Included:(All)
Excluded:(None)
Native library location: (None)


* Go to https://www.eclipse.org/downloads/
source folder #2:
* Download: "Eclipse IDE for Java Developers"
stendhal/tests
* Unzip the download and run Eclipse
Included:(All)
* In Eclipse, close the "Welcome" window
Excluded:(None)
Native library location: (None)


You can click on the following images to see them in large.
default output folder: stendhal/bin

</pre>
<gallery>
<li> On the "Libraries" tab: click on the "Add JARs" button and select all the files in stendhal/lib</li>
File:Eclipse_00.png|On the first run of Eclipse, this "Welcome" window is shown. Please close it.
</ol>

Eclipse should be able to compile the source code now. There could be a little yellow sign (signalling warning messages) before your project folder but there must not be red X (error messages). The package explorer should now display the "src" folder below the root folder with a different icon, the icon is like a small grid.
</gallery>
Note: If you installed Eclipse in Ubuntu via a package manager, also install: "eclipse-egit"

== New Project from Git ==

In Eclipse:

* Open menu "File -> Import
* In the dialog select: "Git -> Projects from Git" and click "Next".
* Select "Clone URI" and click "Next".
* Fill in the following information:
** '''URI''':
*** GitHub readonly: <code><nowiki>https://github.com/arianne/stendhal.git</nowiki></code><br>(if you have a github account, please go to https://github.com/arianne/stendhal and click on "Fork" to create you own copy of the repository and then use that in Eclipse instead)
*** GitHub read/write (SSH): <code><nowiki>git@github.com:arianne/stendhal.git</nowiki></code>
* The result of the fields are filled in automatically, click "Next"
* On the Branch selection page, keep everything selected and click "Next"
* Under "Destination" choose the directory where you want to download the source code and select "Next".
* Eclipse will now download Stendhal from git, this may take a while
* "Import existing projects" and select "Next"
* "Finish" import of project Stendhal

==Trouble Shooting==
==Trouble Shooting==
menu Windows | Preferences | Java | Installed JREs
* there should be at least one entry with a valid JAVA_HOME path (make it so so JDK compliance is 5.0 ?)


After completing the import wizard, Eclipse should look like the following screenshot:
If you happen to get this:

'' The method getLayerVector() is undefined for the type MapMapConverter.javastendhal/src/games/stendhal/toolsline 111''
[[File:Eclipse 10.png]]
* please right click your project folder again --> properties -> java build path.

* in the [source] tab there should only be stendhal/src, so remove stendhal/tiled/src
There is a project called "stendhal" listed in the Package Explorer view. There may be a tiny yellow triangle in front of the blue project icon. But if you see a red circle or a red exclamation mark, something went wrong. In this case there will be an error in the "Problems" view at the bottom.
(This entry has higher priority than the tiled.jar in the libs folder but this code is highly outdated)


==To make it run the server in Debug mode==
== Start StendhalServer ==

* In the toolbar there is the "Debug" button, which looks like a little, green bug. There is a little black arrow on the right side of it.

* All other settings ("include system libries", "Stop in main", ... can be left at their default value.

on the [Classpath] tab:

And then the server should be started.
And then the server should be started.


NOTE: On newer Eclipse versions, the [Classpath Entries] are under Dependencies tab.
==To make the client run==

== Start Stendhal Client ==
# Open games.stendhal.client.update.Starter.java in the editor
# Open games.stendhal.client.update.Starter.java in the editor
# Then again the small black arrow on the right side of the green bug. (Or you may also choose to use the "Run" command instead of "Debug" in case you only want to debug the server component.)
# Then again the small black arrow on the right side of the green bug.
# Select "Debug Configurations" (or "Run Configurations...").
# Java Application -> new-icon, and it should be prefilled.
# Select Java Application and click the "New" button in upper-left corner.
# On the [Classpath] tab - button "Advanced" - (*) add folder | OK - and select the project root folder. | OK
# On the [Classpath] tab select "User Entries" - button "Advanced" - (*) add folder | OK - and select the project root folder. | OK


== Making patches ==
yay shiny new client, shiny server

If you have modified and tested the code and want to send us a patch, please see [[How To Create Patch For Stendhal]].


==Running JUnit Tests in Eclipse==
==Running JUnit Tests in Eclipse==

# If you are runing JUnit tests in Eclipse, there are some additional things to be taken into account:
This is an advanced topic. If you make changes to the Java code, it is a good idea to run the automatic test.
# Eclipse always automatically sets up a new run configuration for you if you invoke the "Run As" -> "JUnitTest" context command on a class or folder. It creates a default classpath configuration derived from the project settings in this run configurations. So there is missing the 'Stendhal' root folder in the classpath, which results in failures running some test cases. To fix this, open the run configurations and add the 'Stendhal' root folder like described above for the client configuration:

# On the [Classpath] tab - button "Advanced" - (*) add folder | OK - and select the project root folder. | OK
Setting up JUnit tests in Eclipse:
# After adding project-root to your classpath, Eclipse should automatically exclude the folders "src/" and "tests/". If not, exclude them together with "tools/" and "tiled/src/".
# Click the arrow next to either the green "Run" or "Debug" button.
# Select "Run/Debug Configurations...".
# Select "JUnit" in the left column and press the "New launch configuration" at the top of left column.
# Give it a unique name, like "Stendhal Tests".
# Select "Run all tests in the selected project, package or source folder".
# OPTIONAL: (this step simply reduces the number of directories that Eclipse will search in for tests)
## Press "Search".
## Select "tests" folder under Stendhal root directory and press "OK".
# Under "Test runner" select "JUnit 4".
# Under "Classpath" tab select "User Entries" and press "Advanced" on the right panel.
#* NOTE: There should already be a folder under "User Entries" with a "(default classpath)" suffix. Do not delete this folder.
# Select "Add Folders" and press "OK".
# Select the Stendhal root folder and press "OK".
# Now click "Add JARs..." on the right panel.
# Under the Stendhal root folder select all the .jar files in libs and press OK.
# Now press "Apply" to save the configuration or "Run" to save and run it.
