Building the Codename One Netbeans plugin.

[Codrut Gusoi]

I figured the discussion forum is a better place than GitHub issues for this. Continuing from: https://github.com/codenameone/CodenameOne/issues/1561  

I commented out these lines:

But now i get:

Also when opening the project I get:

Check out the cn1-binaries project. It includes all the binaries required to build everything, the core vm JAR is just a set of stubs: http://github.com/codenameone/cn1-binaries

Ok I've managed to build the CodenameOne.jar and I checked with a decompiler that my modifications are present there.

Now the only problem I have is how to use this CodenameOne.jar with an existing application. I've tried adding it to the https://github.com/sdwolf/AssertException/tree/master/lib folder but It does not seem to have any effect.

See: http://www.codenameone.com/blog/use-the-source.html

Generally you can just replace JavaSE.jar with the JavaSEPort build and the CodenameOne.jar to get this working.

Holy flying meetballs, I finally managed to make it run, but not without some problems:

First, I had to add the JavaSE port to the Compile Tests tab in the Libraries menu (not documented in the blog post).

Then I also get the following error:

Probabily related to the fact that I had to comment the following lines in order to build JavaSE:

I will create a pull request with the changes now that I could test them live.

Is it ok if I also create a pull request with a "contribution guide" in the project's README.md file?

[Shai Almog]

I told you to copy the .skin files from an existing jar or run the build_skins ant target either one of which would have solved the issue with JavaSE.
The guide predated test support so it doesn't mention that.
