In [this ImgLib2 example](https://github.com/imglib/imglib2-tutorials/blob/ea30fb4c1bf587888c8832f3e27ad8312565fba2/src/main/java/Example4b.java#L138-L143) it seems to work.

I added a point by editing the [↗️ original post](https://github.com/imagej/tutorials/issues/80#issue-530084264).

@fmeyenhofer did you see the comment in the source code? https://github.com/imagej/tutorials/blob/c78764438d774295d00fc8a4273e4c4f25c8ad46/maven-projects/dynamic-commands/src/main/java/DynamicCallbacks.java#L29-L31 But I don't think any active issue existed so far to track this, so we can now link to...

I tried to achieve this by adding: ``` mvn dependency:get -DremoteRepositories=imagej.public::default::https://maven.imagej.net/content/groups/public -Dartifact=net.imagej:imagej:2.0.0-rc-71 mvn dependency:get -DremoteRepositories=imagej.public::default::https://maven.imagej.net/content/groups/public -Dartifact=sc.fiji:fiji:2.0.0-pre-10 ``` [](https://mybinder.org/v2/gh/imagejan/imagej-tutorials/pre-install-dependencies) (see https://github.com/imagej/tutorials/compare/master...imagejan:pre-install-dependencies) While this populates `.m2/` with dependencies as expected, it's not...

I tried [running `nbconvert`](https://github.com/imagejan/imagej-tutorials/commit/660b25fe1b1bf20ee46c0efae9c5eea3d0c0228f) but was running into issues. Will investigate more as time permits. For the python kernel and `pyimagej`, I run [`imagej.init()` from python in `postBuild`](https://github.com/imagejan/imagej-tutorials/commit/a9876cfdfdfacbdfd2f4b2638d45ff839dea0c80), which worked,...

Binder looks into the root level or into `./binder` to find the `environment.yml` file, but AFAICT only allows a single environment per repository/branch. To allow having a minimal environment for...

I assume you mean [`WidgetDemo.java`](https://github.com/imagej/tutorials/blob/0553124c8e0b722733ddc15fc32398821bac0d9e/maven-projects/widget-demo/src/main/java/WidgetDemo.java) in this repository, but it would be nice to also keep the Javascript (in [`scripting-javascript`](https://github.com/scijava/scripting-javascript/blob/74e67c291ba2a4048d5c43b5d29424ebc4144ade/src/main/resources/script_templates/Intro/Widgets.js)) and Beanshell (in [`scripting-beanshell`](https://github.com/scijava/scripting-beanshell/blob/36dfaa0acd5004acfa7762455540c4c44e440c30/src/main/resources/script_templates/Intro/Widgets.bsh)) script templates up to date.
