Custom theming no more possible in v1.20.4 (missing base.less)

[hschaefer123]

Using 1.18.12 i was able to automatically change blue_theme properties using ant and compile it using less. This was quit nice because i was able to recreate theme on library updates.

Inside 1.20.4 there is a line

@import "../../../../../Base/baseLib/baseTheme/base.less";

including some base parts that are not part of the SDK?!?

I think to be able to create your custom theme this file should also be part of the sdk!

Besides SAPUI5 using the server side theme generator i think inside openui5 it should be possible to create custom themes using less!

Hi Holger,
we are currently discussing how to deal with this issue and we won't have an answer before next week.
Thank you for your patience and have a nice weekend,

Any News?

We are still working on a solution.

In 1.20.7 there is now again a way to build custom themes with less.

The missing base.less files can now be found in

• resources/sap/ui/core/themes/base/base.less
• resources/sap/ui/core/themes/sap_bluecrystal/base.less
• resources/sap/ui/core/themes/sap_goldreflection/base.less

But you have to manually change the import statements to point to the files above.
I hope this fixes the problem for now.

We are currently still working on a theme concept for OpenUI5 that enables custom theme builds.

Regards,
Matthias
