Faced the same issue each time I'm restarting the Macbook pro M1, and a random Reddit thread provided me with a way to fix it. Open a terminal and run,
sudo codesign --force --deep --sign - /Applications/Eclipse.app
Not sure why this codesigning fixes the problem. But seems to be a bug in the eclipse itself. Hope this helps someone.
I faced the same issue each time I restarted the Macbook pro M1 Max,(Note Eclipse was downloaded via Homebrew) and tried below but it turned out to be "/Applications/Eclipse.app: Is a directory"
sudo codesign --force --deep --sign - /Applications/Eclipse.app
the issue was the file structure Eclipse saved was different (you can check the file structure by cd to the Eclipse through the terminal) as per the file structure, the path was
sudo codesign --force --deep --sign - /Applications/Eclipse\ JEE.app
I hope this helps someone.
If you want to move your eclipse folder into Applications, then by all means, do it. You do not have to copy the folder – just drag it wherever you want.
In OS X, it doesn't matter where applications are. You can put them wherever you like.
Inside, you'll find Eclipse.app, which you can run as an application. It's not uncommon for the actual .app files to reside in some subfolders of /Applications.
A simple Google search stating "eclipse in mac installation" gave me the following page:
http://www.cs.dartmouth.edu/~cs5/install/eclipse-osx/
The following are the contents of the page, excluding pictures, treated to conform to actual information:
Note that the tutorial assumes you're using Eclipse as a Java IDE. If you use Eclipse for any other programming language, adapt as needed.
Go to http://www.eclipse.org/downloads/ to download a copy of eclipse.
Search for "Eclipse IDE for Java Developers". On the right is a green, downward-pointing arrow. Next to that are links labeled "Mac OS X 32 Bit" and "Mac OS X 64 Bit." Click on the "Mac OS X 32 Bit" link. (Even if you have nice, new 64-bit Mac, it should run the 32-bit version just fine.)
After pressing the download button a page will appear telling you what is the location from where you are downloading a file (usually it is a fileserver or an academic institution hosting the file). Press the download button (a green arrow pointing downwards) and download the package.
The download will go to your Downloads folder. You will normally have an icon for the Downloads folder on the right-hand side of the dock. Find your downloaded package folder in your Downloads folder, and drag it to the Desktop. Then double-click it. You will see a folder named "eclipse".
Drag the "eclipse" folder into your Applications folder. The easiest way to do so is to open a new window in the Finder and click on Applications in the list you get on the left-hand side. Then drag the "eclipse" folder in with the other applications. Make sure that you do not drag it into a folder that's already within Applications. In other words, when you're done, the Applications folder should have directly within it a folder named "eclipse".
3.1. (This step is not required, but it's strongly recommended.) Double click the "eclipse" folder. You'll see an application named "Eclipse"; it has a purple icon with white horizontal stripes. Drag it into your dock. Now you will be able to launch Eclipse by clicking on the icon in the dock.
You may now drag your downloaded package folder to the Trash. Empty the Trash whenever you wish.
When you launch Eclipse for the first time, you'll be asked "'Eclipse' is an application downloaded from the Internet. Are you sure you want to open it?" Click "Open."
You'll see a window asking where your workspace is located. You can choose whatever place you want for your workspace, but it's easiest to just use the default you're given. I recommend that you just click the checkbox next to "Use this as the default and do not ask again" and then click "OK."
Click on the folded-over arrow on the right. You won't see this screen again, even if you quit Eclipse and relaunch it.
Now you'll see a screen with lots of buttons and panes, but nothing of consequence. You have now installed Eclipse!
If you CD to the eclipse installation directory using terminal, then you will see there is a directory called eclipse.app. CD to Eclipse.app\Contents\MacOS under that directory there should be an executable called eclipse.
I believe you can launch eclipse from the commandline by executing the eclipse executable with the -clean argument, as below:
./eclipse -clean
Quote: "On Mac OS X, you start Eclipse by double clicking the Eclipse application. If you need to pass arguments to Eclipse, you'll have to edit the eclipse.ini file inside the Eclipse application bundle: select the Eclipse application bundle icon while holding down the Control Key. This will present you with a popup menu. Select "Show Package Contents" in the popup menu. Locate eclipse.ini file in the Contents/MacOS sub-folder and open it with your favorite text editor to edit the command line options."

I have everything installed, eclipse and avr-gcc, xcode, literally everything and the paths on eclipse are supposed to be detected automatically, but whenever I open eclipse it gives me an error that avr-gcc cannot run due to its path not being available, and idk what to do about it by any means
