Add gradle + Standard project structure

[TheBestPessimist]

This PR adds gradle support for dependencies, and also updates the code to a structured layout.

Left to to (if desired by @Mamiglia ):

• add a main package, ie. com.mamiglia
• relocate .build folder (to where?)
• relocate Installer folder (to where?)

Fixes: #19

[Mamiglia]

I saw a todo, asking for which is the current version. It is 1.2.1

For JNA: It's JNA-platform

[TheBestPessimist]

The changes should almost be finished, however i have the following error when running:

[Mamiglia]

It doesn't find the icon which was in "/resources/tray_icon.png". you probably moved it. Set the correct path at line 18 of Tray.java

[TheBestPessimist]

Works, it changes my wallpaper!

Another issue: when i right click tray and click settings, it gives another error:

[Mamiglia]

I can't understand the error at the moment, I will look further into this tomorrow

[TheBestPessimist]

In that case, please check the PR. Check the left TODOs in the description, and think if you desire to change those.
I didn't check how they work, so you might need to instruct me, or test yourself.

When checking the PR, each commit can be read chronologically, so that you see what I changed and why.

If you think my PR is good enough, feel free to merge.
If you think changes are still needed, please ask for those changes.

If something doesn't make sense, please ask.

Ok, the issue was caused by gradle not building the Intellij Swing desgner that I used to design the UI. I changed a setting in Intellij to make it work: https://stackoverflow.com/a/55725767/9419492 read the comments if your Intellij is > 2019.1

[Mamiglia]

Ok now the only thing left is the .build folder: where does it belong? It's a folder containing all the necessary files that I use together with Install4j, which is an external program that creates the installer

[TheBestPessimist]

I have never used Install4j, however since it's not part of the source code, nor is it a resource needed during application run, it can stay in project root folder as it is now.

gradle not building the Intellij Swing desgner

I suggest you go and 👍 this issue and the 2 related ones, so that Jetbrains sees if people are affected by it: https://youtrack.jetbrains.com/issue/IDEA-223518

It seems to be mentioned in the docs as well, the green box at the top: https://www.jetbrains.com/help/idea/gui-designer.html.

This is unfortunate (maybe?) because with gradle you could have created the jar for the project simply by running gradlew jar. Maybe in your case this is not a problem as you are using install4j to generate the installer.

[Mamiglia]

Ok, added the 👍 to the issue. I did find this plugin that should've handled the thing automatically https://github.com/File5/intellij-idea-guidesigner-plugin, but probably due to my inexperience I couldn't make it work

[TheBestPessimist]

You can add the plugin and push and i will check it out. That's the best way to learn how to use gradle.

[Mamiglia]

Tried to add the plugin as described by the github page, but still it doesn't work if I don't enable the right setting in the settings. I even tried some variations, but no way to make it work, it always give some error about a missing class (I think it's a class needed for the UI builder).
If we can't find a way to make it work I'll just revert the last commit

[TheBestPessimist]

Yep, i cant figure it out either, sorry. ¯\_(ツ)_/¯

Just revert then merge.

[Mamiglia]

Thanks for all the help!
