Eclipse Helios seems to be corrupted - eclipse

I am working on an application in Eclipse Helios and since yesterday every change in the code is not being applied when running the application. I have no idea what is going on. Is my Eclipse corrupted? Have some of you faced such situation? Many thaks.

You have probably disabled the automatic build, so Eclipse never compiles your changes. Check the main menu Project -> Build automatically.

Eclipse doesn't save the previous settings like workspace & Plug-ins

I am using Eclipse Neon on my MacBook & every time I start Eclipse it prompts me for my workspace again and again even though I set it as my default one.
Same goes for the plug-ins I have installed , I need to install eclipse decompiler every time I load eclipse.
I get an error like : "This wizard helps you to import and reinstall previously installed plug-ins. It is triggered because
either you are launching eclipse for the first time or your Eclipse has been updated."
Can someone please assist me with this issue ?
I had the same problem after updating my Mac to Sierra: Eclipse would not remember the default workspace. After moving Eclipse into the Application folder, the problem disappeared.
The issue seems to come from a Mac OSX Sierra feature called 'path randomization' (see eclipse bug 507328). The actual solution to avoid the path randomization seems to be for eclipse to provide signed .dmg images (bug https://bugs.eclipse.org/bugs/show_bug.cgi?id=461670).
Two workarounds that I can suggest are:
Start from the eclipse oomph installer when installing eclipse (see https://www.eclipse.org/forums/index.php?t=rview&goto=1754574#msg_1754574)
Start the actual eclipse executable file instead of opening the .App container

Eclipse Wizard does not close on "finish" in a production environment

I have an eclipse plugin which runs fine in the eclipse version i'm using for developing it. It basicly also runs fine if i export it and install it in a fresh keppler version.
My plugin contains a New Project wizard to create projects which can be used with the plugin.
Now if i used this wizard in my development eclipse if i click finish, everything runs fine the project is created and the dialog is closed.
If i do the same in the fresh keppler installation, the project will also be created and everthing seems to be correct but the dialog won't close until i hit cancel.
Now i really wanted to come up with more information but in the development environment there is no exception occuring.
Also when i start the fresh keppler one with the -debug option i won't get an exception if i hit finish().
Any ideas what could cause this problem or how i could get more information on this?
It is always worth looking in the .log file in the workspace .metadata directory when something unexplained happens to see if something has been logged.
In fact it is worth checking the log once in a while during plug-in development just in case something has been logged.

Eclipse Indigo crashes after installing GWT

I was trying to set up GWT(Google Web Toolkit) on my system using it as a plugin for eclipse Indigo. I am currently on a Ubuntu workstation. Upon restart after the installation, eclipse simply crashes without any error info. I did look around here on stack overflow , as well as on google about what could be done, but the things which seemed to work for others do not seem to work for me.( deleting certain .jar files, deleting the metadata folder in the workspace).
Any help would be great.
Regards
Problem solved. There is a bug in Indigo , exposed by the plugin. All that needs to be done is to check for updates first and then install the plugin. The bug has been fixed in one of the point updates.

Eclipse's Juno doesn't recover changes

I've turned to Eclipses's Juno lately , it works fine , but when I make any change to any file and run the project again : changes aren't recovered (specially for web development) , and I have to close the IDE and restart it again ; in order for the changes to take place..
I didn't encounter that in latest eclipse editions , is there a solution for that problem ?
Are you sure you've "built" your changes from the Project menu, or have automatic builds enabled?
as mentioned above:
The problem was solved after I had restarted the computer , till now I have no clue about the cause of the problem.

Eclipse Helios settings are gone everytime I restart it

Everytime I restart my eclipse helios I see it having lost all its views, perspective and all its setting. And as I have a maven eclipse installed on it, it starts updating nexus-maven-repository-index central which seem to a decade to do its thing.
I was very happy with Galilio but I needed to work on a project that asked me to use helios or above. And I've been feeling burnt ever since I switched to Galileo.
Does eclipse helios has any incompatibilities with any of Java 6 versions. I am using jdk1.6.0_32.
Could someone please help me with these problems.
Thanks
Worst case, once you have resetup all the preference, view & perspective, do the following
Export > general > Preferences > somename.epf
next time when you open eclipse and if the preference is wiped out, then you can
Import > general >preference>somename.epf.
It doesn't fix your problem, but will get you up running...
