⁠Pull and run

docker pull stden/java-run-swing:latest
docker run --rm stden/java-run-swing:latest java -version

Run a Swing JAR from the current directory:

docker run --rm -v "$PWD":/app stden/java-run-swing:latest \
  xvfb-run -a java -jar my-app.jar

Compile a Java source file named Hello.java. Then run the program:

docker run --rm -v "$PWD":/app stden/java-run-swing:latest javac Hello.java
docker run --rm -v "$PWD":/app stden/java-run-swing:latest xvfb-run -a java Hello

A test must close its windows and exit when it finishes.

⁠Checks and source

CI compiles a small Swing program, opens a JFrame under Xvfb, and checks its exit status.
