Once the download has completed, locate the downloaded file. This file will be a compressed (i.e., a ".zip", or ".tar.gz") file. Uncompress this file into the directory of your choice. It doesn't really matter where you put the Eclipse installation folder as long as you know how to retrieve it. You can optionally create a shortcut of the Eclipse IDE executable file ("eclipse.exe" on Windows, or "eclipse" on Linux, or "Eclipse" on Mac OS X) found in the directory that is created. To start Eclipse you just double-click on the executable file or the shortcut
I had a project that was creating log files in the /Applications/Eclipse.app/Contents/MacOS/ folder. This caused the signature mismatch. If this happens for you, cd into the above directory remove everything other than the default (eclipse directory). After that, debugger99's suggestion of signing will work.
It seems changing Info.plist or eclipse.ini changes the package and MacOS considers it a threat and blocks the application which is good thing in itself. However, not applicable for this case since we know we have to make changes in either of this file to use custom JDK. To avoid this, we will perform a code sign of the Eclipse package as demonstrated in next section.
Double click on the Eclipse.app, so that application can start. This is important because changing eclipse.ini without this would result in package being corrupt in some cases.
The speculation from @eskimo was very insightful, after installing several plugins code sign does indeed show many modified files (and the application refuses to start). In my case this was due to installing plugins from the eclipse marketplace.
I had to change something in the eclipse.ini, which is of course inside the package, that breaks the codesignature. But even better is that I run ABAP Development tools (better said JCo) and that plugin creates a log file inside the app package. So it breaks while starting ...
Eclipse itself runs on a JVM. There is no need for this JVM to be what your project standardized on, because any project in eclipse can be configured to run on whatever JVM you want. Thus, if it sounds like you need a newer JVM version to run eclipse on, just do that. It doesn't matter if your project won't run on that.
More generally getting an ExceptionInInitializerError is a wrapper exception. The real cause is inside it. Inspect the traces somewhat more rigorously; start eclipse from the command line (open a terminal, then run /path/to/Eclipse.app/Contents/MacOS/eclipse - now you can see the terminal output, that might help. "ExceptionInInitializerError" says almost nothing and has a billion causes. You want the exception that caused that, that'll be much more specific. It's somewhat unlikely to be related to running on an M1; very little stuff in the java ecosystem cares one iota about what chips you run it on.
The SWT libraries for Mac Arm64 (AArch64) architecture are available for testing. Note that an Arm64 Java virtual machine (JVM) is required to run the libraries. Also note that the Eclipse IDE and SWT for Mac x86_64 architectures can already run on Apple silicon chips using the Rosetta translation process on an x86_64 JVM.
Host: Talk a little bit about what are your next steps? What are you getting ready for? People are going to be listening to this the Thursday before the eclipse actually happens. What is some advice? What do you want to tell people? Get some glasses.
So, the eclipse corona that we will see in the path of totality, the Parker Solar Probe will actually go to that environment to measure locally the conditions of the corona so that we can really answer some of the most pressing questions not only of heliophysics, I think of astrophysics, of physics in general. The two questions are, when you look at the Sun, the yellow ball that we look at, the temperature of that surface, compared to the corona, the corona is much, much hotter than the photosphere of the Sun. The corona is millions of degrees.
This is the simplest way to start using Sloeber as it bundles inone single download a complete setup including a stable version ofthe Eclipse CDT and the latest stable build of our great Arduinoeclipse IDE!
To install some or all of the Eclipse tools, get an installation compatible with the desired tools and use the respective software site URL in the Help > Install New Software wizard. Based on the version of your eclipse:
