The Eclipse plugin does not have a successful location installed

Take the success of the GEF not installed as an example

Under the Eclipse root directory:

Eclipse–clean–console–noexit

Right click on the window title bar, properties, tick in the quick edit mode, so that you can right click in the command Line window to paste the contents of the Clipboard into the command line window

Execute command:

SS ORG.ECLIPSE.GEF

No results, indicates that GEF is not successfully installed

To install using a command:

Install File:dropins/gef-update-3.10.0/plugins/org.eclipse.gef_3.10.0.201506010206.jar

The folder name and file name change according to your own situation

Again

SS ORG.ECLIPSE.GEF

Discover that the GEF installed ID is 413

Execute command:

DIAG 413

That's very clear.

Draw2d not installed,

The same way as above to install draw2d
