Old projects reborn - MoneyTimer

This is another tool, I've tried to update in order to withstand the test of time - MoneyTimer

What does it do ?
It measures time and calculates every second how much time it costed all participants.
Great for consultation meetings!

You can try out the latest release here:

What I can learn from it?
- Java 8 Lambda expressions
- Simple Multi-threaded application
- Swing

How to contribute: 
Check the instructions at the github repo page.
If you are wondering what to contribute: there's a list of ideas in the issues page


Tune in, because more complex ones are coming ...

Check out my other project that can interest you. This time about HTML generation via XSL transformations - http://javamissionary.blogspot.bg/2016/04/old-projects-reborn-filesystem2html-tool.html

Old projects reborn - FileSystem2Html tool

As everyone in the IT business, I have quite a few of my own projects. Most of them rot in solitude and are rather dusty... So, I decided as a way of exercise as well as a check how have technologies developed and my own views on code cleanness, tests' quality and overall project usability, to make them more development-friendly.

In short - I'm reviving my projects (both university and personal ones) so that they are easy to setup, run and contribute to if there's a willing person.

I'm starting with this small project: https://github.com/leni-kirilov/FileSystem2Html/

What does it do:

- it's a simple Folder structure scanner

- it can build an HTML/XML report of the folder structure

- it can rebuild that folder structure elsewhere (without the content, obviously)

My "beautiful" swing UI

Very useful if you like a certain folder structure, and don't have the time to remove all the files or whatever. You can easily mimic it. Quite a simple app.

Now to the contribution part:

- It's an open source project 

- Java 8 required

- built with Maven 

- a list of TODOs and ideas where one can get started! I've listed ideas based on effort. 

I would start with the small ones. 

The project builds automatically and measures code coverage (yes, there are unit tests there!)
(Thank you Travis-CI, Coveralls and Coverity!)

So that's pretty much it.

I can't wait until I see someone energetic about such a tool

Best of wishes!

PS:

Please be gentle :) I know there's some pretty lame code out there!

Eclipse and maven-properties problem

Today, I'm going to share a problem which I think it's quite common:
- importing Java Maven projects into Eclipse and expecting Eclipse to just work with it.

You do:
1) sync from source control
2) import existing maven projects to eclipse
3) see many red errors in Eclipse.
4) yeah , I forgot to set the Maven settings file
5) still some projects are failing
6) try to fix each problem 1 by 1

Why does it happen like that?

Most common is that it will set a Java Compiler version which is from the POM.xml but then the JRE environment specified could be... just not right. So your POM.xml says "compiler version 1.7", but the Maven projects you import are automatically assigned Java1.5...
So errors like
- You cannot use @Override here
or for java1.7
- new ArrayList<> constructor not found (or not valid expression).

So you have to go to each project, reconfigure build path parameters to point to JRE1.7 manually, even though you have specified JDK1.7 as installed JDK.
Imagine fixing this manually for 20-50 projects (you've just been moved to moderately progressed project)

Even if you explicitly set the Maven settings in the Preferences menu, you would not solve your problem.

The single solution is to:
1) delete all projects ( only from Eclipse )
2) reimport them, because NOW you have set the Maven settings BEFORE the importing...

Just crazy... not being able to automatically adapt the projects to the new maven settings file... not even "clean" and "maven update" help...

Best wishes,
