Installation
To install JBang Idea plugin you have two options:
Install via IntelliJ’s Preferences/Plugins by searching for jbang in marketplace.

OR
Visit JBang Idea plugin marketplace page and use the Install button.

Once installed you can open an existing JBang script or create a new JBang script.
JBang Location
The plugin automatically locates the JBang executable using the following order:
-
Custom path (if explicitly set in settings)
-
JBANG_HOMEenvironment variable - checks$JBANG_HOME/bin/jbang -
PATHenvironment variable - searches forjbang(orjbang.cmdon Windows) in system PATH -
Default location - falls back to
~/.jbang/bin/jbang
If the automatic detection doesn’t find your JBang installation, you can explicitly set the path in the IDE settings. Navigate to Tools > JBang in the Settings/Preferences dialog and enter the full path to your JBang executable in the "Custom JBang Path" field.

The "Effective JBang Path" field shows the actual path that will be used, which will be your custom path if set, or the automatically detected path otherwise.
