JAR File Features

Note: if you want to embed Imposter in your JUnit tests, see JVM bindings instead.
You must have a JVM installed. Java 11 and 15 have been confirmed as compatible. Others may also be, but are not currently tested.
Note: As of version 3, Imposter no longer supports Java 8. If Java 8 support is required, Imposter 2.x is still available, but may no longer be maintained.
Run the JAR as follows:
java -jar distro/all/build/libs/imposter-all.jar \ --plugin <plugin name> \ --configDir <config dir> \ [args]
...ensuring that you choose the right plugin you wish to use, for example:
java -jar distro/all/build/libs/imposter-all.jar \ --plugin rest \ --configDir /path/to/config \ [args]
$ java -jar ./imposter-all.jar --plugin rest --configDir ./example-api Starting server on port 8080... Parsing configuration file: someapi-config.yaml ... Mock server is up and running
