How to get started?

[drdev]

I need some basic help with understanding the codebase. I am completely unfamiliar with Java programming so bear with me if all this is really trivial.

Is there a way to insert breakpoints within forge-ai to study the call-stack? I was inserting the breakpoints in Eclipse and doing the "run as Java application" on forge-gui and fail to trigger any of the breakpoints. Specifically, I was studying "CurseAI" and inserting breakpoints in "pumpTgtAI" in PumpAI.java.

You need to use "Debug As" instead of "Run As" if you want to hit breakpoints.

I keep getting

RA layer request failed
svn: REPORT of '/forge/!svn/vcc/default': Could not read response body: connection was closed by server (http://svn.slightlymagic.net)

on trying to import from svn checkout at random points.

[moomarc]

I found I had better luck with avoiding timeouts with the checkout when I used command line instead of Eclipse for the initial checkout. Perhaps give that a try xbon.

on svn i get an error as well w/o subclipse, e120106: ra_serf: The server sent a truncated HTTP response body. at random points. i can't complete the checkout in subclipse or svn right now.

should I be using the latest version of sliksvn, or 1.6?


edit: got tortoisesvn and did a clean up and update to pick up from where it left off; I'll see if this works.


So I checked out with tortoiseSVN successfully, however now when I try to run as java application, it can't find the main class file....

"Selection does not contain a main type."

The new main class is in forge-gui-desktop.

Trying to run from SVN, when performing the run-as command as described, I get the following error

Do you have Java 7 installed? Java 7 is required for switching on strings to be supported.

[timmermac]

Yep. Java 7 is running on my computer.

[moomarc]

Is Java 7 set as your compiler though? If you were using java 6 when you first set up your svn, you possibly need to change that

I've been having trouble getting m2e & Eclipse setup, so I thought I'd take up friarsol's suggestion and try IntelliJ. It seems to be working properly, but I'm not quite sure how to get started with building the project (specifically the desktop app).

I configured the global SDKs to point to my Android SDK install and my system install of JDK 7:

Platform SDKs

I then configured my forge project SDK to 1.7. However, when trying to build the project with the following settings, I get the message "Error:Android Pre Dex: [forge] Android SDK is not specified".

Build/Run options

I've tried changing the SDK for the top level forge module (see next pic), but then builds quickly fail with the following output:

Not sure if I'm messing up something Android specific or missing something else entirely. Would greatly appreciate anyone's direction and assistance here!

"FSkin > can't find skins directory!"
That's the problem that you need to fix. I'm away from my computer and haven't tried setting up Forge in IntelliJ yet (just started using it recently) so I'm not sure what to do off the top of my head.

I believe you need to set both your working directory and the classpath of the configuration to ..\forge\forge-gui-desktop

the main Class should be forge.view.Main

[troyready]

That was it -- thank you so much!

Hi, I have downloaded the project and installed it according to the instructions. I have been able to build the typical jar file (via Maven) correctly. But if I want to run/debug with Eclipse, once I click the run as Java application, Eclipse doesn't provide me a list of classes to choose from.

If I download just the forge-gui-desktop module, then the expected textbox with the classes appear and I can choose, but possibly I lack an additional folder or library and I get an error similar to the "can't find skins directory".

What do you recomend me to try next? I have mostly worked with JDeveloper rather than eclipse, and the project management (compilation,...) is somehow different.

Hi, I'm trying to set up my development tools using the 'Forge: How to Get Started Developing Forge' page on the wiki. I have a question about Subversion: Should I compile it myself, or can I use one of the third party binaries, and if so, which one would you recommend? (Edit: By Subversion I mean SVN, not the card :p )
