+# RDF Connect: JVM runner
+
+
+## Build
+```sh
+gradle build
+```
+
+
+## Use in a pipeline
+
+The file `index.ttl` suggests how to specify the JvmRunner.
+We currently face a problem of how to point correctly to the jar, here it is hard coded.
+
+For the test pipeline there is a test processor in `test-processor`.
+In their `build.gradle`, it points to the types jar from the runner, all Processors require this jar to implement against the expected `Processor<?>` abstract class.
+
+```gradle
+implementation files('../../types/lib/build/libs/types.jar')
+```
