#

this is my maven config

#

what am i doing wrong?

final surge
#

ah

#

so by default maven pulls dependencies from the maven central repository

#

this one is not on central

#

it might be a good idea to put it on central in some way so it doesn't die whenever the OpenNMS repo dies

#

but until that, you can add a repository

# 
<repositories>
    <repository>
        <id>OpenNMS</id>
        <url>https://repo.opennms.org/maven2/</url>
    </repository>
</repositories>
#

there is kinda a newer website with

#

some different instructions

#

but also note that they are licencing it with GPL

#

not L-GPL

#

which means you can't make a product with it

#

(GPL is "infectious")

#

but you can pay them for a better license - idk if thats how that works

@final surge i tried
putting the repositories u mentioned both the opennms and mibble.org
they both seem to not work

bump

tiny wyvern
final surge
#

sorry i've been doing work work the last few days

tiny wyvern
#

maybe there is a way , i can put "whatever maven is trying to find(artifact??) " on nexus and it can pull from there?

#

i am not sure if this is how it works

final surge
#

im looking now

#

but please confirm that you understand what i said about the licensing

tiny wyvern
final surge
# tiny wyvern

yeah so i think opennms might require some authorization or something

#

there is a way to add this all to your local repo

tiny wyvern
#

local repo? like with nexus?

final surge
#

i mean your .m2 on your machine

#

so if you have the jar for this

tiny wyvern
#

maven is pulling the jar for mibble?

final surge
#

no

#

well it could

tiny wyvern
#

i am sorry i am confused a little

final surge
#

if it was on any repo

tiny wyvern
#

what is it pulling

final surge
#

so there is a jar for mibble out there in the world

#

we cannot find it on any maven repositories

#

so when you put a dependency declaration it wont find it

#

but if you physically have the jar on your machine

tiny wyvern
#

aha , can we build the jar?

final surge
#

lets just skip ahead to "you have the jar"

tiny wyvern
#

gotcha

final surge
#

if you have the jar on your machine

#

you can run this command

# 
mvn install:install-file \
   -Dfile=<path-to-file> \
   -DgroupId=net.percederberg \
   -DartifactId=mibble \
   -Dversion=1.6 \
   -Dpackaging=jar \
   -DgeneratePom=true
#

and that will put the jar inside a special folder on your computer

#

the ".m2" folder or "your local maven repo"

#

before checking the internet for a dependency it will check that folder

#

this is how it avoids redownloading dependencies

tiny wyvern
#

this makes sense

final surge
#

it downloads them once then uses that

tiny wyvern
#

so the only issue remaining is , how to get that jar?

final surge
#

so you can take the jar and put it in your local maven repo and then everything else will "just work"

#

right

#

so if you want to use 1.6 you need to find it out there

#

Use an Older Version — Versions 1.2 to 2.3 of Mibble were licensed under GNU GPL but with an exception allowing linking with non-GPL code, effectively making the license LGPL. All these versions contain bugs and are unmaintained, but they may still work for you.

tiny wyvern
#

i dont think i want a specific version

final surge
#

well you might

#

because 1.2 to 2.3 are under LGPL

tiny wyvern
#

cuz of license?

final surge
#

yes

tiny wyvern
#

i can pay for the licesnse

final surge
#

okay then

tiny wyvern
#

its 1500 EUR???

final surge
#

the jar also appearrs to be here

tiny wyvern
#

ooo

final surge
tiny wyvern
#

so i need to download the tar , extract is , then put it where exactly

final surge
#

last LGPL version which you dont need to pay for

tiny wyvern
#

in project folder?

#

and give maven the path with the command u mentioned

final surge
#

well

tiny wyvern
final surge
#

okay so unzipping that folder gives a directory

#

you might need to do that for all 3 of these jars

#

idk what the other 2 are

forest hull
#

you had a versioning issue with mibble?

final surge
tiny wyvern
#

grammatica is need for mibble

final surge
#

and past 2.3 its GPL not LGPL

forest hull
#

why are you creating your own artifact under mibble?

forest hull
final surge
#

and the OpenNMS repo either doesnt have it or requires auth to get it

#

there is also a repo on the mibble site but that is also broken

forest hull
#

yeah, just tried it out, seems like its not hosted anymore

final surge
#

better safe than sorry

tiny wyvern
#

really appreciate the help
