Both 26.0 and 25.1 on OS X 10.12 via homebrew, using the Spacemacs configuration. I recently tried the weaving technique from http://orgmode.org/manual/noweb_002dref.html#noweb_002dref : * Create #+NAME: TestDemo2 #+BEGIN_SRC java :classname TestDemo2 :noweb yes :tangle yes <> #+END_SRC #+BEGIN_SRC elisp (format "%s" (org-babel-expand-src-block testdemo2)) #+END_SRC **Let's see what our code-weaving produces :PROPERTIES: :header-args: :noweb-ref testdemo2 :END: *** this is how we will assemble our code: #+BEGIN_SRC java public class Yo { public static void main (Args[]) { #+END_SRC *** body #+BEGIN_SRC java return "The test worked!"; #+END_SRC *** foot #+BEGIN_SRC java // <> }} #+END_SRC *** weave together - which will weave together the above blocks to produce this: #+BEGIN_SRC shell :results org :exports none cat TestDemo2.java #+END_SRC I have tried both (setq org-use-property-inheritance (quote (noweb-ref))) and (setq org-use-property-inheritance t), both at org-mode load and from within the org file in question. Also, note that I am using the 9.0 syntax, which I believe Spacemacs loads as part of its org-mode layer. The result is always an empty TestDemo2.java file. What’s interesting is that if I run org-babel-expand-src-block I see this: public class Yo { public static void main (Args[]) { return "The test worked!"; // }} cat TestDemo2.java If I add :noweb-ref to each block, it works. - OS: darwin - Emacs: 25.1.1 - Spacemacs: 0.200.9 - Spacemacs branch: develop (rev. 4b92183c) - Graphic display: t - Distribution: spacemacs - Editing style: vim - Completion: helm - Layers: - System configuration features: NOTIFY ACL GNUTLS LIBXML2 ZLIB TOOLKIT_SCROLL_BARS NS MODULES My org-mode config (org-plus-contrib-20170210) ;; org-mode (with-eval-after-load 'org ;; Turning `org-use-property-inheritance' on can cause significant overhead when doing a search, which is why it is not on by default.
