Eclipse removes external imports after saving the java file

Question

I have imported a few external library imports in a java file. After saving the file eclipse auto removes these imports.

Quick googling showed me results about organizing imports. But these are disabled in eclipse work-space.

How should I prevent this behavior?

This is probably save actions https://www.eclipse.org/pdt/help/html/save_actions.htm — Guillaume, May 28 '19 at 09:57
If this is the "organize import" option, only the unused import would be removed, not the external library. What version of eclipse are you using ? — AxelH, May 28 '19 at 10:47
@AxelH For eclipse, since it cannot actually map the external import, it identifies them as unused. — YetAnotherBot, May 28 '19 at 11:38

It was in fact inside Save Actions.

Although the Perform the selected actions on save was unchecked, these settings were enabled inside Configure Project Specific Settings and the corresponding project.

If you convert your project into a Maven project, you can add your imports into the pom.xml file.
Thus all your external exports would now be considered as internal ones.
If you don't want to convert your project to Maven, you could Add External libraries to Eclispe. See here

That would work. But the project uses a ant file for build. – YetAnotherBot May 28 '19 at 10:33
