How to setup Eclipse for CanaryMod API autocompletion?

[HermannnTheGerman]

Hi there,

For my son I bought a book from Andy Hunt about learning Java by writing plugins for CanaryMod server. My son loves to play Minecraft and also wants to learn programming so I thought I could combine best of both worlds.

The book does not teach how to setup a proper development environment. Instead it suggests to use a text editor with Java syntax highlighting (Sublime). However, I believe that programming is a lot easier if you use a full featured development environment, e.g. Eclipse, that also supports autocompletion.

I found a page that explains how to setup Eclipse to enable referencing JavaDocs from CanaryMods Maven repositories:

http://www.poweredbyjeff.com/canarymod- ... -tutorial/

That page states, I have to create a Java project, convert it to a Maven project and then edit the pom.xml file to set the source control management URL to:

http://repo.visualillusionsent.net/repository/public/

However, that does not work for me. Eclipse shows the error message "No versions available for net.canarymod:CanaryLib:jar:[1.0.0,) within specified range"

If I point the browser to the above URL at visualillusionsent.net, I get an error 404 page.

Is the repo down or has it moved? Did I miss something?

Thanks a lot for any help or advice.

It does seem that the repo isn't at that URL anymore. You could try get on the irc to talk to someone who may know, sorry I don't.
You could build against CanaryLib yourself or put a downloaded lib in <your maven repo>/repository/net/canarymod/CanaryLib/1.2.0-SNAPSHOT although you would also need to setup vi utils too.

Hi WWOL,

Thank you for your reply and for confirming that the provided SCM URL is outdated and no longer valid.

I skimmed through pom.xml at GitHub

https://github.com/CanaryModTeam/Canary ... er/pom.xml

and found this promising URL:

http://repo.visualillusionsent.net/repository/internal/

However, I don't know nothing about Maven and its configuration. Therefore I'm at a loss whether this URL is a valid replacement for the outdated SCM URL. It's just try and error for me currently. At least, this URL is valid and, using a browser, I can further recurse into

net/canarymod/CanaryLib/1.2.0/

but Eclipse now gives me the following error message:

"Missing artifact net.canarymod:CanaryLib:jar:1.2.0 pom.xml /Test-Java-Project line 28 Maven Dependency Problem"

Hi there, good find with that URL.
I'm not sure if it's intended for public use but it does seem to work.

I can't really help with that error without more info but I did get a project to build correctly using the following pom.xml

Code: Select all

Hi WWOL,

Thanks for providing this pom.xml file. I removed the <SCM></SCM> part in my pom.xml file and added the <repositories></repositories> element of your pom.xml file, basically recreating your pom.xml file:

Building (Run as -> maven install) takes much longer now, that's very encouraging.

However, it stops with a different error message regarding "viutils":

Error code 403, Forbidden -> [Help 1]


Looks like Maven/Eclipse tries to download an artifact from

https://libraries.minecraft.net/net/visualillusionsent/viutils/1.4.1/viutils-1.4.1.pom

but gets an HTTP 403 "forbidden" error. To me that's not surprising as I'd not expect that any of the visualillusionsent artifacts (e.g. viutils) would be available from mojang's servers. What is surprising is, that "viutils" is not downloaded from http://repo.visualillusionsent.net/ or similar servers in that domain.

I guess it couldn't find it in the vi repo for some reason and tried the MC one, I'm not 100% on how Maven works.
You could try http://nexus.visualillusionsent.net/con ... ps/public/ as the VI url.
