Eclipse Plugin Project Run Configurations

Does anyone know how can I fix this problem?
I am doing a plug-in project with GEF.
I have created a new Eclipse Application when I selected Run As>Run Configurations...>Eclipse Application>New launch configuration. Then at the Main tab I put this Location: ${workspace_loc}/.metadata/.plugins/org.eclipse.pde.core/runtime-New_configuration.
In my xml-file I described my application:
<extension
id="application"
point="org.eclipse.core.runtime.applications">
<application>
<run
class="tutogef.Application">
</run>
</application>
When I execute the plugin it shows the message below:

Cannot create Eclipse workspace

Today I downloaded Eclipse Neon. When I ran it for the first time it asked me to select a folder as my workspace. After doing this it throws me an error which redirects me to a log file inside the folder I selected to save my workspace:

Sorry for the long post. Any ideas?

You are starting Eclipse using Java 9. This currently does not work with recent builds of Java 9.
Eclipse bug 493761 describes this problem and is currently scheduled to be fixed in Eclipse 4.6.2 (Neon.2)
Until Eclipse 4.6.2 is available use a Java 8 JDK to run Eclipse.
Update:
To run Eclipse with Java 9 you need to modify the 'eclipse.ini' file in your Eclipse installation and add the line:
--add-modules=ALL-SYSTEM
as a line following the -vmargs line in the file. This adds the Java 9 module containing the missing classes.
Eclipse Oxygen.1a (4.7.1a) due for release on 11 October 2017 will have full Java 9 support.
Also see Configuring Eclipse for Java 9 in the Eclipse wiki.

Made it to work in OSX Sierra by adding the following:
--add-modules=java.se.ee
at the end of eclipse.ini

Works for me using the most recent Java 9 early access build b143 and Neon Release 4.6.0
Just add
--add-modules=java.annotations.common
to the eclipse ini after -vmargs

Adding --add-modules=java.se.ee, after -vmargs in STS.ini or eclipse.ini will solve the launching issue.
-vmargs
--add-modules=java.se.ee
-Dosgi.requiredJavaVersion=1.8
-Xms40m
-Dosgi.module.lock.timeout=10
-Xverify:none
-Dorg.eclipse.swt.browser.IEVersion=10001
-Xmx1200m
refer to the link: https://bugs.eclipse.org/bugs/show_bug.cgi?id=493761 for more information

I've just had same issue today, the issue in my case was because I was using jdk 11, good tip about the eclipse.ini file, in my case it was indicating clearly it was expecting to use jdk 8, downloaded that version, replaced the jdk path in the env params and it is working now.

Eclipse PHP Developer Tools crash after opening a PHP file

i've a problem with eclipse on windows. Eclipse is crashing after opening a file. See details:
im using eclipse PDT (PHP Developer Tools) helios 64-Bit BuildId 20100617-1415.

I've created a new Project in Windows, then i copied the code in Windows-Explorer in the workspace/project-folder and execute the refresh-command over the whole project.
When i'm trying to open a file in the project, eclipse says no response. So that i only can kill the process. The last time i get a errormessage:

Can someone help me? I want to work with eclipse, but it seems that i've to use an other IDE for Webdeveloping.

Your JVM has exhausted the limit on Permanent Generation (PermGen) memory (which is not the general heap). Please see http://wiki.eclipse.org/IRC_FAQ#I.27m_having_memory.2C_heap.2C_or_permgen_problems.2C_what_can_I_do.3F , https://wiki.eclipse.org/FAQ_How_do_I_increase_the_permgen_size_available_to_Eclipse%3F , and http://eclipsenuggets.blogspot.com/2007/10/does-your-eclipse-3.html .

Eclipse plugin not executed

I wrote an eclipse plugin which should be executed at startup of workspace (see Executing eclipse plugin automatically). It works perfectly when I try it out with the Run button. But now I created an update site and installed the plugin via the update manager. I don't know why but now it is not executed when eclipse workspace starts.
What could be the problem here?
Content of plugin.xml:
<?xml version="1.0" encoding="UTF-8"?>
<?eclipse version="3.4"?>
<plugin>
<extension point="org.eclipse.ui.startup">
<startup class="plugin.first.handlers.StartClass"/>
</extension>
</plugin>
I found some additional info in /workspace/.metadata/.log:

Why do I get java.lang.NoClassDefFoundError?

I found the solution myself. You need to add jars you used in your project to your build configuration (see attached picture).

It seems like you are running Eclipse Juno, which comes bundled with OSGi v3.8, which does not uses the Eclipse in built console, but the console is now contained it's own bundle. You need to add that bundle. That is what your OSGi is complaining about. You also need to add some felix bundle to get the new console run.
In all, at a minimum, you need to select following bundles in your OSGi run configuration:
- org.eclipse.osgi
- org.eclipse.equinox.console
- org.apache.felix.gogo.runtime
- org.apache.felix.gogo.shell
Or, if you want to use the eclipse built in console, you can enable it by passing following VM arguments:
-Dosgi.console.enable.builtin=true

I faced same issue. Was just about to download ggts again. But just deleting. Metadata folder from workspace solved it. But after that u have to import and set all configuration again.
