It worked for me, although I'm using Openjdk 8 instead of 11. I'm guessing the problem lies there?

I can check with Openjdk 8...

WTF!!! @UCW9TUDNK thanks a lot... it built with Openjdk 8

Glad it worked!

@UCW9TUDNK maybe it's a stupid question but can you give me a hint as to how I can try the examples out? I do a lein cljs build once but then I open the index.html file (`firefox resources/public/index.html`) I get a blank page... (I tried it again for the simple-sidebar example)

It looks like the rc template is empty by default (just an empty div) https://github.com/gadfly361/reagent-cookbook-template/blob/master/src/leiningen/new/rc/core.cljs

I'm not familiar with reagent-cookbook, but I guess they expect you to fill in the code yourself?

If you're like me and would like hot-reloading when you play around, using reagent-template might be a better solution https://github.com/reagent-project/reagent-template Then just run lein figwheel after lein new reagent <name>. With the rc template you would have to refresh the page on every change.

achsoo... sorry I didn't open the code... i thought these were like examples

sorry about that

No worries, I can see how it's easy to misunderstand [=

I think after spending the last couple of hours trying to figure out the problem with lein (which turned out to be an openjdk version issue) I've lost it

right now, I'm configuring my CI for the project

You're probably calling map with a single argument, which makes it return a transducer (see (doc map)). If you want it to return a collection, you have to pass it as the 2nd argument.

oh - ok
