Ankit Fulzele's answer helped me with minor adjustments.

I use Dark Theme on Mac and the following worked for me for Eclipse 2019-06:

Add the following lines to ~/.p2/pool/plugins/org.eclipse.ui.themes_{version}/css/dark/e4-dark_basestyle.css

Tree {
        font-family: '#org-eclipse-ui-workbench-TAB_TEXT_FONT';
}

Instead of setting a fixed font, this will pin it to whatever the "Preferences -> General -> Appearance -> Colors and Fonts -> View and Editor Folders -> Part title font" is configured to.

Note: It would make more sense to pin this to another setting, e.g. to "Preferences -> General -> Appearance -> Colors and Fonts -> Basic -> Text Font", but couldn't find the CSS reference for it.

Note: This update will change not only the "Project Explorer" tab, but others as well.
