When running a successfully built image for a Clojure application on Toolforge, the application fails to start and the log contains a single entry: bash: line 1: java: command not found

Changing the Procfile for the application to contain an absolute path to the java binary (/app/.jdk/bin/java) fixes the problem.

To replicate

Build and run a Clojure web application, for example version 1.0.4 of the Technical Documentation Dashboard (GitLab repository) on Toolforge.

What happens?:

The application fails to start with the following error: bash: line 1: java: command not found

What should have happened instead?:

The application should start and be available under its URL.

Workaround:

Change the content of the Procfile

From:
web: java -cp target/dashboard-standalone.jar techdoc.dashboard.core

To:
web: /app/.jdk/bin/java -cp target/dashboard-standalone.jar techdoc.dashboard.core
