I have seen many interesting (and duplicated) questions here about "sharing or using classes between projects".
I see this as quite practical but the proposed solutions I have read about definitely assume certain prerequisites such as:
While likely acceptable solutions, I am looking for an alternative with perhaps greater flexibility and portability.
I am thinking of learning how to use gradle (or maybe maven, I haven't fully committed to one or the other yet). And from what I understand it may be possible to manage shared classes with one of these dedicated dependency management programs.
Theoretically is this possible? Can I setup a gradle or maven enabled java project to handle and keep uptodate personal classes on a local server or folder on a portable drive or cloud mirror?
The way I understand dependency management at the moment (on a superficial level, I know the devil is in the details) is that for a configured dependency management enabled project, gradle/maven will handle classpath additions and the actual version specific comparison, retrieval and storage (and maybe even compilation is possible but I don't know about this) of JARS from external sources.
Rather than go through the steps to setup classpaths to jars I have to keep current and compiled myself as proposed in many other answers, I am considering creating a dummy project on a server that I can put generic classes which I could then point numerous individual gradle/maven enabled java projects to use. (I think most people would be able to keep them as stand alone classes, but I think I might need to keep them in a dummy project to be developed and debugged in context from a main class. I am somewhat new to java architecture so if the only thing that would make this solution impossible is pointing to a "project" instead of a "library" I can definitely adjust from there. (Assuming I am even applying the concept of the "library appropriately).)
Other info: I would like this to simplify personal dependency using both Netbeans and eclipse IDE's and work cross platform (but Linux and Windows is what I plan to test it on)
So you're looking for portability, and you don't want to compile your java class that you want to share between projects. And you don't mind a local deployment.
The first thing that comes to mind for me is Git - I'm not sure if Gradle/Maven deal in the gritty underworld of the uncompiled. Composer will pull in git repos for php, so that got me thinking.
If you're happy with one-way sharing of code among projects, Git has submodules that let you do that.
But searching around, apparently there's a git script that goes one step further - Git Subtrees. I also found an intriguing tutorial that will allow you to make changes to common code that you change while working on any particular project that shares it - so obviously be careful - but check it out and see if the Subtrees script might suit your needs.
