Job found still running after platform shutdown eclipse
If your eclipse crashed and refuses to start, saying something along the lines of: Job found still running after platform shutdown. Jobs should be canceled by the plugin that scheduled them during shutdown, then
try the following.
$ rm-rf YOUR_PROJECT_DIR/.metadata/.plugins/org.eclipse.core.resources
Start eclipse. However, all your projects will be gone.
You can import them via File ->Import ->Existing Projects into Workspace;then select the directory where you had your projects.
EDIT: I just found a better way. (source)
$ rm YOUR_PROJECT_DIR/.metadata/.plugins/org.eclipse.core.resources/.snap
This way you do not need to reimport your projects.
As IGx89 suggested
in the comments, you can also try the following:
$ rm YOUR_PROJECT_DIR/.metadata/.plugins/org.eclipse.e4.workbench/workbench.xmi
