Try this solution mentioned in this discussion.

I just ran into this problem using standard (not Stanford) Eclipse.
By now this is probably moot for you, but I’ll post my solution for
future travelers.

The launch configurations for Assignment 1 default to Applet, so the
containing Karel application isn’t launched. To solve this, create
and use new Application launch configurations for each file.

If you already tried to run some of the files, delete the Applet
configs created so you can reuse the names:

1. Open the project properties (e.g. right click on Assignment 1 and select Properties).
2. Select Run/Debug Configurations.
3. Select and Delete each configuration.
4. Click OK.

May the Force be with you.

Create Application configs:

1. Right click on java file (e.g. CollectNewspaperKarel.java) and select Run As > Run Configurations…

2. Select Java Application in the left pane.

3. Click New Launch Configuration (the icon of a document with a +).

4. Type a name for the configuration and set its Main class to the associated file (e.g. CollectNewspaperKarel).

5. Click Apply then Run. (This should run correctly and create a useful entry in the Run History.)

Eclipse will still try to default to Applet, so you will henceforth
need to launch these configurations from the Run History (either from
the Run menu or the pull down on the run button). If you accidentally
launch as default, it will add a useless Applet configuration to the
Run History (e.g. CollectNewspaperKarel (1) ). You can delete this
from the Run Configurations dialog to keep the Run History tidy.
