+# io.vertx Dependency Bundle
+
+   
+Issue [#141](https://github.com/NubeIO/iot-engine/issues/141): Bug related to dependency resolving.
+
+`io.vertx` classes are only loaded by main classloader not [isolated classloader](https://vertx.io/docs/vertx-core/java/#_verticle_isolation_groups) i.e. the verticles that are 
+deployed 
+dynamically using [Maven verticle factory](https://vertx.io/docs/vertx-maven-service-factory/java/) cannot find `io.vertx` classes.
+
+Ideally, this module loads all required `io.vertx` dependencies to `edge-bios` module main classpath (or `server-bios` if
+ required).
+The `bios` module should use following in its `build.gradle`:
+ 
+``
+compile project(':core:iovertx')
+``
+
+> If any new io.vertx dependencies are used by the project (mainly installable modules), then these dependencies must
+ be added to `build.gradle` of `iovertx` module.
+
+Alternative is to use  `compile "io.vertx:vertx-dependencies"`. However, there are many unnecessary dependencies.
