We Keep Coding

Why do I get this error in a Dynamic Web Project in Eclipse?

I have this error message even though my program is working.
Problems occurred when invoking code from plug-in: "org.eclipse.jface".

That looks like Eclipse bug 442762 which was fixed in Eclipse Photon (4.8). So you need to use Photon or the current 2018-09 release (soon to be 2018-12)

It seems like you need to upgrade for further projects.

Has anyone had this and solved it?

Ok, the error was being generated, due to the gradle plugin being 2.0, gluon released a document stating this. I uninstalled Plugin 2.x and installed 1.x, solved the problem. Soon after, I did an update of it, and it kept working. Thank you very much to everyone. This error occurs in Oxygem 1.A
Eclipse gluon new project does not finish

Details of the Context:
Java version is 1.8.0_91, 64 bit;
Eclipse Neon 4.6;
Linux Debian 64 bits;
Oracle Virtual Box 4.3
Robot Framework 3.0 (Python 2.7.9)
It seams to be an issue on the plugin, but I would like to know if someone has found an workaround. https://github.com/NitorCreations/RobotFramework-EclipseIDE/issues/72

As you're trying to setup a Robotframework IDE in Eclipse, I wondered if you have tried RED which is developed by Nokia.
In my mind its has more features (debug line-by-line), syntax highligting, code completion & custom run parameters and it still under active development. NitorCreation hasn't updated the repository since October 2015.

Eclipse Package Explorer Not Displaying Properly

When I select the "Package Explorer" tab, I get a vast white space with only the top of my 10 projects showing up, and not on the left side of the pane like it should, but instead on the right side. It's weird. If I click on it, I get a "Problem Occurred" pop box saying "An error has occurred. See error log for more details. Could not initialize class org.container.directory.Logger".
The error message in /.metadata/.log is this:
!ENTRY org.eclipse.e4.ui.workbench 4 0 2013-09-25 13:36:17.223

It appears to be related to org.container.directory.Logger. "Logging bundle must not be null." Anyone have any idea how to fix this? Thanks.

I haven't figured out how to fix it, but I have observed that it only occurs when I have a Servers project in my workspace - I suspect it has something to do with the fact that that project doesn't have a classpath...

There is the File DirectoryClasspathContainer_1.0.0_EclipsePlugin.jar in C:\Program Files\eclipse\plugins. Delete the file.
