Jenkins core has removed GIF and PNG icons as of Jenkins v2.333, in favor of the previously added SVG icons.
Plugins, that don’t interact with icons at all, are unaffected by this change.
If a plugin reads icons from its icon path, it typically does the following in jelly:
<img src="${imagesURL}/16x16/fingerprint.png" alt="" height="16" width="16" />
<!-- or -->
<l:task icon="images/24x24/document.png" href="" title="${%Modules}" />or in groovy:
img(width:"16", height:"16", src:"${imagesURL}/16x16/next.gif")A plugin can do that in Java too, but that is, by far, less common.
Jelly offers a couple of properties to access an icon class instead of an icon path. Jenkins core will display a GIF, a PNG or an SVG, based on the Jenkins version used. The properties <l:icon class> and <l:task icon> are used based on the location the icon is displayed in.
The format is icon-<icon> icon-<size>. <icon> represents the name of the icon that used to be read from a path.
<size> represents the icon size.
The following values for <size> are available:
| Path size attribute | <size> attribute |
|---|---|
16x16 |
sm |
24x24 |
md |
32x32 |
lg |
48x48 |
xlg |
Pick the appropriate <size> attribute according to the path size the icon has.
Jelly example:
<l:icon class="icon-fingerprint icon-sm" />
<!-- or -->
<l:task icon="icon-document icon-md" href="" title="${%Modules}" />Groovy example:
l.task(icon:"icon-next icon-sm")More information about Jelly tags provided by core to display icons can be found in its jelly documentation.
