Sorry for speaking too cryptic. This part of the project will make the |
| 29 |
installed Java packages appear in list of libraries in Eclipse. |
| 30 |
We have a tool named "java-config" which can do all these and written in |
| 31 |
Python. Jython may help you to easily integrate Java and Python (There |
| 32 |
was some project of Eclise that would result in writing plugins in other |
| 33 |
languages but I don't know its current status) It also has a cli |
| 34 |
frontend which you may consider as an alternative. You could also |
| 35 |
directly parse package.env files installed with every Java package. (I |
| 36 |
think you already have Java packages in your Gentoo system which you may |
| 37 |
take a look) |

I don't understand how you plan to proceed with this. There's no Java |
| 62 |
package to Gentoo package mapping anywhere and even if that can be done |
| 63 |
that should be a central tinderbox that merges packages and creates a |
| 64 |
list of classes installed with it. |

Here's a good alternative for you. |

| 79 |
It's a trivial bug in java-config, which you will be interacting with |
| 80 |
for this project. |
