Publish Bisq 2 libraries for re-use in Bisq-mobile

[HenrikJannsen]

We need to publish the Bisq 2 modules used in Bisq-mobile as jar libraries.

• Publish as jar to local maven repository
• As there are many modules, avoid duplication of the Gradle tasks (maybe create plugin?)
• Include protobuf files and resources
• Use those libraries as dependencies in Bisq-mobile
• Add publish-all convenience task

We could use jitpack instead/additional to the local maven repository, but this will require verification.
I think local maven is at least during development easier and faster.

We could also consider to create a shadow jar to pack all into one jar. But I think having individual jars is probably better. If we package all we must avoid the non-android compatible modules like java-se, os-specific, apps`,...

When I used that approach in my POC branch I had issues with plugin id("bisq.java-library") as on android that caused a missing dependency to 'bisq::platform' which is not a java library and I did not manage to publish that. I guess it has to be recreated on the android project. By replacing the id("bisq.java-library") plugin with:

java
id("bisq.java-conventions")

I could resolve that issue.

At the network module when adding the publish tasks (at network-identity) it caused problems on the network sub-projects (like tor). I did not manage to resolve those issues. Some Gradle experts will know for sure how to deal with that....

@rodvar Can I assign that to you?

[rodvar]

@HenrikJannsen sure thing!

starting work on this one

[rodvar]

Current status:

• can merge from main, all the work of ongoing adaptations has already been merged
• code is fully J17 compatible now
• Ideally (TBD) we should set that in the gradle setup (J17 compilation), but still target Java 22
• local publishing to maven has not been merged, part of this issue tasks is to put it in place fully working for all the modules we need

Modules to work out:

- bisq-easy
- bonded-roles
- chat
- common
- contract
- i18n
- identity
- network
- offer
- persistence
- security
- settings
- support
- trade
- user
