I did the following:
1) Close eclipse
2) Delete everything from the subfolder
\.metadata\.plugins\org.eclipse.core.resources\.projects in my workspace. In my case this was
folder C:\workspace\.metadata\.plugins\org.eclipse.core.resources\.projects.
3) Restart eclipse
I also set my M2_REPO classpath variable in eclipse (this is a maven based project):
4) In eclipse, select Window - preferences - java - build path - classpath variable - new
5) Set name=M2_REPO
6) Set path=the path to your .m2 folder (you will need to find your .m2 folder and use the correct path for your environment, in my case is was C:\Users\pondolal\.m2\repository).
7) Restart eclipse
8) Clean and build projects

If I hover over a variable, I don't see a quick evaluation either, instead it shows the type.
I used to be getting "eclipse "com.sun.jdi.InternalException: Got error code in reply:35 occurred retrieving 'this' from stack frame.", but for some reason, now I'm not.

Perhaps I thought this is because of memory issues so I tried to increase the memory in eclipse.ini file:
-vmargs
-Xmx16G
-Xms3G
-Xss16M
-XX:MinHeapFreeRatio=50
-XX:MaxHeapFreeRatio=60
-XX:+UseParallelGC
But still it fails with same Stackoverflow error.
I'm running my headless eclipse application via a batch file. The content of batch file looks like this:
#echo off
start eclipse -application com.headless.application -consoleLog indir C:\workspace\TestData
So my first doubt is that whether my headless application is considering the eclipse.ini file or not? If not what are other ways to pass eclipse.ini file directly in above eclipse call?
In case if it is considering the eclipse.ini file, what other options can be tried?
Note: In case of same GUI application, it is working fine.
I downloaded the checkstyle plugin for university in order to check the code like my professor wants it. We got an xml configuration file and i created with that another checkstyle configuration (Preferences -> Checkstyle -> New...) Also I set it as default. Now we have to create an automatic formatter like "Rightclick project -> Checkstyle -> Create Formatter-profile". Now I get an problem popup from eclipse with the message:
"An internal error occurred during: "transformCheckstyle".

MY SOLUTION:
"Delete all folders from USER_FOLDER ( .p2 .eclipse ) and PROGRAMFILES. Remember to reboot!!!! Now all works fine with eclipse oxygen and git project"
The GIT plugin of Eclipse tries to detect whether to use the GIT executable of the OS, or the build-in GIT. Therefor it uses a bash command.
Before the Windows Creators Update, the bash command did not exist (unless you've installed CygWin or a similar program). With the Windows Creators Update, a new feature Windows Subsystem for Linux is added. When the bash command is first called, it asks whether to install this feature or not.
So in order to fix GIT in Eclipse, you just have to manually run bash once and install it. You may have to activate Developer Mode in Windows.
I had the exact same issue: Eclipse was not responding when trying to configure git.
I used Java VisualVM and discovered that Eclipse was not responding because of Eclipse JGit was searching for git.

I am on Windows, Git for Windows was installed, but for a strange reason the Environment Variable pointing on Git was not defined.
I had to add the directory of git.exe (C:\Program Files\Git\bin) in the System variable named Path.
Eclipse is not freezing anymore.
Adding git to the path variable on Windows 10, using Eclipse Oxygen worked for me! TY :D
Eclipse may be searching for a bash executable.
If you have Cygwin installed, add the Cygwin bin directory (for example, C:\cygwin64\bin) to your Path environment variable. Then restart eclipse.
The Cygwin bin directory includes bash.exe.
Check if you have already installed Git or not.
See if git variable is properly set in environment or not.
Try to execute git command in command prompt, it should work first.
Once all above steps are Okay, try restarting eclipse in clean mode.
I am trying to export a couple of deployable features in Luna, but I always get the error message below. I have two plug-in projects, a corresponding feature project for each and a category definition. With this set up Kepler exported the deployable features into a folder flawlessly, but with Luna there is always this message.
How can this be solved? Is there any other relevant information I can post?
Message:
An internal error occurred during: "Export Features".
